LearningAid for Android 2.0 adds all the features of the iOS version to Android.
Plans going further (in order of importance to me):
1. Web app release
2. Website for advertising the product
3. Multiple language support
4. Linking Helpers to your account
5. Rebranding
I plan to release new versions of LearningAid first to iOS, then, a few days later, to Android. Some features are/will be platform-specific.
LearningAid is a perfect place to study. You can make collections of words and meanings, called Helpers, and play them. The playing system is forgiving and motivating and focuses on learning from your mistakes. If you think you made a perfect Helper, you can easily share it with one link.
