I’m developing a Crash 1xbet predictor and the first milestone is a solid data backbone. What I need right now is a lightweight app (web or desktop, whichever you are fastest with) that lets me enter raw game information by hand, stores it safely, and immediately turns it into useful insights.

Once stored, the data should be processed in real-time so I can quickly spot trends that feed the eventual prediction model. Data you’ll be handling • User betting patterns • Real-time game statistics (crash multipliers, timestamps, etc.) Key features – Clean manual-entry form with validation and du...
