Your flashcards, now on your Home Screen.
FlashStacks puts your study cards on your Lock Screen and Home Screen as beautiful widgets. Glance at a question between meetings. Tap to reveal the answer. Move to the next card without ever opening the app. Learning fits into the moments already filling your day.
Study without opening an app
Your stacks live as widgets — always visible, always ready. Cards rotate automatically throughout the day, so every time you check your phone there's something new to learn. Tap to reveal, tap to advance
.
Built to actually work
FlashStacks uses spaced repetition — the same science behind Anki — so cards you struggle with come back sooner and cards you've mastered fade into the background. Study smarter, not longer.
Beautiful by design
Every stack gets its own colour — soft pastels or bold modern tones. Widgets match your stack's palette. Dark mode uses pure OLED black. The whole app feels as good as it looks.
Track your progress
Per-stack stats show your mastery level, response breakdown, and 14-day activity. Build a streak. Hit your daily goal.
FlashStacks Premium
Unlock unlimited stacks, unlimited cards, Lock Screen widgets, and more.
Monthly and Annuals plans available. 3 day free trial included for Annual.
