Great study companion

Really like how easy this app is to use. The home screen widget is a nice touch, and being able to review flashcards without constantly opening the app has made studying feel a lot more natural.

Great easy and cleanly designed app

Nice way to stay focused

I really like how FlashStacks makes studying fit into my day, especially with flashcards sitting right on the home screen or lock screen. The widget experience feels thoughtful and useful. For a future update I’d love to see a little more contrast in the UI to make it even more readable and accessible (in the app). Great start!
