2 screen iphone app very simple layout. I will send the sketches.
1st screen is a 3 field form that will store it in sqlite db and make a POST call to an external API.
2nd screen is a view of sqlite db entries. Users can delete entries which will also make a DELETE to external API.
An additional screen for About us (static text) will be nice.
If you are familiar with iPhone development and Apple's Push Notification service, this shouldnt take more than a day to get it done.
Requires good exception handling and support for app for atleast few weeks after completion.
I will disclose more details based on your comments.
