Gromf helps you to invite friends to your events, without the need to register and without collecting personal data.

Looking for a Facebook alternative for inviting to events (and for an idea for an iOS app), I created Gromf. My main project is the app, but I developed the complete system with web front and back end, so the user base is not limited to owners of iOS devices.
The app serves as an alternative front end for the web version. The UIKit interface uses Auto Layout and adapts to all screen sizes and orientations and is also optimized for iPad. It was developed for iOS 7 while keeping compatibility with iOS 6.

Technologies app: iOS 6/7, Objective-C, UIKit
Website and back-end: PHP, MySQL, HTML, CSS, JavaScript

Note: I removed Gromf from the App Store to concentrate on “LowRes Coder”.
