I have a fully-working Android Studio project (Java) that photographs urine test strips and reads the colours, but its interpretation layer is letting us down: colours are detected correctly, yet the final numbers it returns are wrong. I need someone to dig into the existing code, locate the flaw in the result-interpretation logic, and at the same time refine the overall algorithm so the readings become clinically reliable. Because I’m interested in both fixing the bug and improving the core method, you will be free to refactor, recalibrate, or even redesign parts of the analysis pipeline provided the camera capture and colour-extraction steps remain intact. OpenCV and native Android APIs are already integrated, so you will be working inside that framework. Key deliverables: &bul...

I’m building an online Colour Prediction game under the “Diu Win” brand and need the full website coded and ready for launch. Players must be able to sign in exclusively with their Instagram accounts, so the site has to include a clean Instagram OAuth flow that remembers sessions and handles token refreshes automatically. Gameplay itself is the classic colour-guess mechanic but presented only in Tournament mode—no single-player or open multiplayer lobbies. After joining a tournament, users place their prediction, watch the real-time result animation, and see an instant leaderboard update. On the back end I require an admin panel where I can: • create and schedule new tournaments • adjust odds / colour ratios before a round begins • view live p...

I’m ready to bring a new social media concept to life and need an experienced mobile developer who can build for both iOS and Android from the same code-base. The core goal is a smooth, modern user experience that can scale quickly once we validate the idea. Here’s what I’m after: • A native-feeling app on both platforms, ideally powered by a cross-platform framework such as Flutter or React Native (open to your recommendation). • Clean, well-documented code, structured so new features can be added without rewrites. • Standard social features—secure sign-up/login, user profiles, real-time feed, basic messaging or commenting—and room to expand. • Simple, intuitive UI/UX that’s easy for first-time users to grasp. • Sourc...

I need an automated chat flow built for our WhatsApp sales channel. The goal is to guide prospects from first hello through to purchase, answering common pre-sale questions and capturing qualified leads without human intervention. Key points • Platform: WhatsApp (Business API or a reliable third-party gateway—whatever you recommend). • Purpose: Sales-driven conversations that nurture interest, showcase offers, and push to checkout or live agent when required. • Flexibility: While my priority is converting prospects, the flow should be modular so we can later add product info, order tracking, or follow-up messages. Deliverables 1. Conversation map outlining each step, fallback, and hand-off trigger. 2. Fully configured chatbot deployed to our WhatsApp number, te...

I need a robust automation bot for an Android game that can do three core things: 1. Detect every relevant UI element on multiple screens through image recognition, then tap the right spots to claim the daily rewards without fail. 2. Autonomously solve the in-game maze and pick-pair minigames with human-like speed and accuracy. 3. Run hands-free once launched, logging what it collected or solved so I can review a simple report afterward. Deliverables • Full Android-ready build (APK or script + instructions to run with ADB/Emulator) • Source code with clear comments • Image libraries or model files used for recognition • Quick user guide and a short demo video that shows the bot clearing both minigames and collecting a day’s rewards Acceptance criter...

I have a clear concept for an e-commerce app and a draft requirements document ready to share. The first release will target Android only, so Kotlin or a modern cross-platform toolkit that compiles natively for Android is fine as long as performance stays smooth. Key functions I already know I need are: • secure user profiles with sign-up / sign-in • real-time customer support or chat • live location tracking for deliveries or on-site services • simple attendance logging for my field staff • customer management screens (basic CRM) • product and sales modules that handle inventory, a shopping cart and checkout If you have built similar retail or logistics-focused apps before, I’d love to see a short portfolio or a couple of links.

I’m putting together a brand-new mobile application for Ask Innovations focused on education e learning, and I need an experienced UI/UX specialist who works comfortably in Figma to translate our product requirements into a clean, modern, and highly usable interface. Here’s what I am looking for: • A complete set of high-fidelity screens in Figma, organised into a clear design system and packaged with interaction prototypes ready for developer hand-off. • An iterative approach that lets us review early wireframes, refine the user journey, and lock final visuals before hand-off. • A clear breakdown of your total project fee, optional per-screen pricing, the timeline you’d need, and the payment or milestone schedule you prefer.

I need a complete, stand-alone driver logging application built specifically for the trucking industry. The core objective is to let drivers record and manage every trip while staying fully compliant with Hours-of-Service regulations. Essential feature set • Trip logs: simple start-to-finish capture with location, mileage, and timestamps. • Hours of Service tracking: real-time duty-status calculations that flag upcoming limits before they become violations. • Fuel tracking: gallons, cost, and receipts tied back to each trip. • Log editing & violation removal: supervisors must be able to correct entries while preserving an audit trail that shows what changed and when. I am open to web, mobile, or hybrid stacks as long as the final product is intuitive f...

I have several mobile gaming apps that offer daily rewards after you tap through a predictable series of on-screen buttons. Manually repeating the same taps across each game is time-consuming, so I want a small automation script that can reproduce those clicks for me in each app and loop them whenever I run it. Key points • The taps span multiple games, not a single title, so the script should let me define independent coordinates (or image targets) for each app. • Right now I only need tap automation; however, I may add other gestures later, so please structure the code so extra actions can be dropped in without rewriting everything. • Mobile-friendly tools such as ADB, Appium, AutoTouch, or a lightweight Python wrapper are all fine—as long as setup remains sim...

I’d like a clean, analog-style face for my new Samsung Galaxy Watch 7. The layout only needs to show the current time and date—no extra complications, health rings, or weather data—so the design can stay uncluttered.

Everything should be built in Samsung Watch Studio so I can receive both the editable project file (.gwd) and an installable build that I can sideload for testing. Deliverables • Samsung Watch Studio source file (.gwd) • Compiled install package ready to load on a Galaxy Watch 7 • Quick note explaining how to swap colours or tweak the date format if I decide to adjust it later Once I confirm the final look m...

I am looking for an experienced Full-Stack Developer to build "Vina (வினா)", a highly interactive, bilingual (English/Tamil) test preparation and AI-mentorship app for TNPSC aspirants.

I need an AI-driven IVR that takes new vendors from first phone touch to “ready to transact” without a human agent. The flow must guide callers through document submission, trigger automated account setup and finish with a brief orientation or training segment, all in a single, streamlined call experience with whatusp connection Here’s what success looks like to me: • A conversational IVR in English and Malayalam that recognises voice or keypad input, validates answers and adapts its prompts dynamically. • Secure upload or capture of required onboarding documents, with confirmations sent to both the vendor and our back-office system. • Automatic creation of the vendor record in our CRM/ERP once documents clear basic checks, plus generation of login ...

I need a complete Android mobile application that serves as a social media platform. The core task is to turn my concept into a fully functioning app—from setting up the project in Android Studio, through coding the main social features, to packaging a release-ready APK. At this stage I will provide the feature list, brand assets, and any required APIs; you’ll transform them into clean, well-documented Kotlin or Java code. Expect typical social elements such as user registration, profile pages, a scrolling feed, basic post interactions, and push notifications, but I’m open to your technical guidance on the best architecture and libraries. Deliverables • Full Android Studio project with readable, commented source code • Signed release APK and a debug build fo...

We are looking for an experienced full-stack mobile developer to join an ongoing project built with React Native on the frontend and Node.js on the backend.

I have an idea for a new social-networking experience and now need a skilled Android developer to bring it to market. The concept and basic user flows are already sketched; your role is to translate them into a smooth, modern Android application that can scale. You will design the app’s architecture, craft an intuitive Material Design interface, and connect everything to a reliable back-end (Firebase is fine, but I’m open to alternatives you can justify). Expect standard social features such as secure sign-up/login, profile creation, a real-time feed, messaging or comments, image upload, and push notifications. Performance, clean code, and thoughtful UX are priorities. Deliverables I’ll review for acceptance: • Complete, well-documented Kotlin/Java source code &b...

I want a single, scannable QR code that immediately opens our association’s Zelle donation screen with our designated email address pre-filled. No goals, progress bars, or extra text should appear—just a clean hand-off to Zelle so supporters can give in one step. Please build the code, verify it on both iOS and Android Zelle flows, and deliver it in print-ready SVG or EPS plus a high-resolution PNG I can drop into flyers, emails, and social posts. If you use a generator such as QRCode Monkey, Adobe Illustrator, or a comparable tool, embed error correction at a level that keeps the image sharp even when reduced. Acceptance criteria: • Scanning from default camera apps launches Zelle with the correct donation email populated. • Files supplied: SVG/EPS + 300-dpi PN...

Shopify editing. I have the images and the captions. I need this done curated to mobile mostly. I’ll pay a lot of money to have it done tonight because it’s easy but I have too much to do. I have tons of images.

I need a clean, intuitive platform that lets each of our growers log in securely and review everything we store about their individual blocks. The system must be available both in a browser and as a fully-featured mobile app so they can check information from the field or the office with equal ease. Once inside, a grower should immediately see every data point we hold for that block: soil quality and composition, water-usage records, plant-growth data and any other details we’ve captured for them over time. From there they need three core abilities—simply view the information, update or correct it when something changes, and export professional-looking reports for their own records. I’m open on framework choice as long as the result is fast, reliable and future-proof; a...

I’m ready to turn my e-commerce app concept into a complete, developer-ready Figma file that follows Google’s Material Design system. You’ll start from the brand assets and rough ideas I provide, map out the user flows, move into low-fidelity wireframes, and polish everything into high-fidelity screens. Because product discovery is central to the experience, the product-search journey has to feel lightning-fast and visually intuitive. I want a design library my team can reuse long after this project wraps, so every component, colour style, and type scale should be built into a tidy Figma system. Once the UI kit is in place, please stitch the screens into an interactive prototype—my stakeholders need to click through the checkout path on both phone and tablet breakp...

I’m ready to turn my existing REST API into a polished React Native mobile application. The API is fully documented and the screen designs are complete; what I need now is a clean, TypeScript-based codebase that follows good component architecture and stays as close to pure React Native as possible. Core requirements • Authentication: wire the app to my API using Basic authentication and persist credentials securely. • Navigation & UI: a tabbed interface that presents a master list (pulled from the API) and corresponding detail views, matching the provided Figma files pixel-for-pixel. • Offline experience: cache the entire app’s data locally so users can browse previously fetched content without a connection, with automatic background sync on reconnect...

I am looking for a developer to create a custom IPTV/media player application called Fleezy Player for Amazon Fire Stick, Fire TV, Android TV, Google TV, and similar Android-based TV devices. I am open to an existing IPTV player codebase, template, white-label solution, or previously developed application if it already works very well. The app does NOT need to be built completely from scratch. My priority is getting a stable, professional IPTV player that works properly on Fire Stick and Android TV, supports Xtream-compatible accounts, and can be customized with Fleezy Player branding. The finished application should be delivered as an APK that customers can install directly, including through the Downloader app on Fire Stick. BASIC USER FLOW Customer installs Fleezy Player → O...

I want every single message that reaches my WhatsApp Business account to receive an instant, well-structured reply. The response must open with a friendly greeting, list my contact details, and then show a clear order menu with concise instructions on how to place an order. I do not need the customer’s name merged into the text—the greeting can stay universal. Here’s what I expect from you: • Craft the copy (including emojis or line breaks where they improve readability) so it fits comfortably within WhatsApp’s character limits and looks clean on both Android and iOS. • Format the order menu so customers can see numbered or bulleted options and understand the next step at a glance. • Activate the auto-reply inside my WhatsApp Business settings...

I need a single Android application that brings three abilities together: • show the live HD feed from my existing IP cameras, • let me start / stop recording that feed and push the resulting files straight to my server, and • allow me to toggle an IP-based IoT switch from inside the same interface. A simple email-password login gate is required before anyone can use any feature. Once authenticated the user lands on a dashboard where the camera stream appears immediately; from there a record button begins saving footage and silently transfers it to my server (I will give you the endpoint and credentials). A separate tab or overlay houses the IoT switch with instant on/off feedback. I am open to whichever libraries you prefer—ExoPlayer, VLC, ONVIF, RTSP, MQTT, HT...

I’m ready to commission a cross-platform mobile app that streamlines every aspect of my security company’s field operations. The same build must ship to both the Apple App Store and Google Play so every officer, manager, and client can use a single code-base on iOS or Android. Core workflow • Security officers will clock in at the start of their tour, clock out at the end, and have their total weekly hours calculated automatically. • Hourly security checks are scheduled in advance; if one is missed I need an instant push notification. • While on site, officers write reports, attach multiple photos directly from the device camera, and submit them in real time. • A built-in internal mail system lets officers, managers, and clients message each other w...

I’m looking to launch an iOS-only color-prediction game similar to 55Club/Daman Games, and I need a working demo before we move to full build-out. The core will revolve around a 1-minute WinGo round, so speed and real-time result control from the admin side are critical. Key functionality I must have: • Seamless wallet with deposit and withdrawal, tied directly to UPI payments. • Referral system that automatically credits bonuses. • Admin panel with advanced controls, including manual result override plus full user management (suspensions, balance adjustments, basic reports). The entire flow—from UPI top-up to game play to cash-out—has to feel smooth and trustworthy, even on lower-end devices. I’m working within a 3,000 INR budget, so code...

Please do not bid on this project if you cannot proove that you did a successfull marketing campaign of a brand new app with 0 installs! My health-and-wellness app is live on Google Play but, after a full week of running a Google Ads App-Install campaign that Google rates 95 % optimized, I am still sitting at zero installs. I'm not sure what could be the reason, but if you can proove to me that you understand the problem and you already have dealt with such problem, the job is yours. Acceptance criteria: at least 50 real installs from older-adult devices within the first seven days after changes go live, at a CPI that can be scaled. All account access is ready; I simply need your expertise to turn a well-rated but idle campaign into actual downloads.

I have all core assets—final text, illustrations, audio tracks and several short animations—ready to be assembled into a single interactive ebook aimed at iPads and other modern tablets. Your task is to weave everything together so the reading experience feels native: page-wide transition effects, touch-triggered animations, synced audio playback and smooth navigation throughout the title. The finished file should run flawlessly in Apple Books on iPad and the main Android tablet readers that support EPUB 3 (or an equally capable format you propose). I’m happy to hear your approach, but HTML5/CSS3/JavaScript inside a fixed-layout EPUB is what I have in mind. Needed within one month, so please take on the project only if you can meet that window and demonstrate you have t...

I’m building a mobile application that must perform and feel identical on Android and iOS—I value both equally, so each platform needs the same polish, speed, and attention to detail. My preferred stack is React Native for the shared frontend layer; if you are comfortable weaving native modules or platform-specific tweaks into that workflow, even better. The scope covers everything from setting up the project repository through to releasing a production-ready build on Google Play and the App Store. Along the way I’ll need clean, well-commented code, component-level testing, and logical Git commits so future iterations remain straightforward. Deliverables • React Native codebase configured for Android and iOS • Integration of any native modules we identify as...

I already have a fully working web experience hosted at and I now need the same features packaged as a native iOS application. The core flows that must be replicated are: • User login / logout (exactly as it works online). • The scheduling-alerts workflow, including all current form logic and validations. • The short onboarding sequence you see on first use. Visually, I would like the screens to look and feel just like the website, adjusting only where necessary so they sit comfortably within Apple’s UI patterns and safe-area constraints. I am not interested in push notifications for this release. Please keep the codebase clean, readable, and ready for future updates. At the end I’ll need the full Xcode project, any third-party library notes, and a Te...

I need a clean, fully native Android application written in Kotlin that lets shoppers browse products, add items to a cart, and complete checkout within the app. The flow starts with a simple Email/Password sign-up or sign-in screen; once authenticated, users can move seamlessly through product listings, detailed product pages, a persistent shopping cart, and a secure payment gateway. Because this is core e-commerce, performance, crash-free stability, and responsive UI on Android 8.0+ matter more to me than flashy extras. Jetpack components (Navigation, ViewModel, LiveData) are welcome as long as the codebase stays modular and easy to maintain. Stripe or PayPal SDK integration is preferred for payments, but I am open to other PCI-compliant gateways if you can justify the choice. Delivera...

I need a Flutter developer to build a polished mobile application that lets users browse available time slots and book consultation appointments from their phones. The app must run smoothly on both iOS and Android and communicate with my existing REST-based backend for everything—user authentication, schedule retrieval, booking creation, rescheduling, and cancellations. Here’s what matters most: • Clean, maintainable Flutter code that compiles for iOS and Android without platform-specific hacks. • Solid REST API integration with proper error handling and token-based security. • A straightforward flow where a user logs in, views consultant availability, confirms a slot, and receives an in-app and push notification of the booking. • Responsive, modern...

I need a native Android application whose sole purpose is to help users work smarter and stay organised. The app will be positioned squarely as a productivity tool, so every screen, interaction and workflow should reinforce speed, clarity and ease of use on mobile. I have not finalised a feature list yet and I welcome your input, but I expect the core build to demonstrate typical productivity capabilities (for example: creating and tracking tasks, setting reminders, logging notes or anything you believe will boost day-to-day efficiency). Clean Material-design styling, smooth performance on recent Android versions and sensible local data storage are non-negotiable. If you can architect the project so that future integrations—such as Google Workspace or Microsoft Office—can be a...

I want a clean, responsive website that lets guests reserve rooms at Hotel NoVo Agra without ever feeling they have left our site. The core of the job is to embed a third-party booking engine such as and keep its full payment workflow active, so when a guest completes a reservation the card is charged immediately and the confirmation arrives automatically. Apart from the booking flow, the site only needs the standard hotel pages—rooms, amenities, photo gallery, location map and a contact section—so visitors can browse, then book in a single, uninterrupted path. I’m open to the platform you think best (WordPress with a suitable theme or a lightweight custom build), as long as it is fast, mobile-friendly and easy for my staff to update copy and images later.
