Irregular Verbs Trainer

When I started learning English there wasn’t a suitable app for learning irregular verbs in Windows Store. So I decided to create one. It was written in C# using MVVM approach (Prism library). It allows a user to easily find all three forms and also has some exercises. Eventually has transformed into new app called “Do Did Done”.
