What if every time you unlocked your phone, you learned something new?
We unlock our phones 96 times per day on average. That’s 96 opportunities to review a flashcard, master a language, or memorize important facts. UnlockToLearn transforms these micro-moments into powerful learning sessions.
The Problem with Traditional Learning Apps
Most flashcard and learning apps require you to:
- Remember to open the app
- Manually start a study session
- Fight against the temptation to check social media instead
UnlockToLearn flips this model entirely. Instead of competing for your attention, it leverages the moments when you’re already reaching for your phone.
How It Works
📱 On Android: Learning That Intercepts Distraction
Unlock Trigger
Every time you unlock your Android device, you’ll see a flashcard before accessing your home screen. Answer it correctly, and continue with your day a little bit smarter.
A flashcard appears the moment you unlock your phone
App Launch Trigger
Going to check Instagram? TikTok? Reddit? First, answer a flashcard correctly. This isn’t about restriction—it’s about being intentional with your time and inserting micro-learning moments before potentially endless scrolling.
Answer correctly to proceed to the app you want to open
🍎 On iOS: Widgets That Encourage Learning
iOS doesn’t allow intercepting unlocks (for good privacy reasons), so we’ve built engaging alternatives:
- Lock Screen Widgets — See flashcard questions right on your lock screen (iOS 16+)
- Interactive Home Screen Widgets — Flip cards and mark answers without opening the app (iOS 17+)
- Siri Shortcuts — “Hey Siri, show me a flashcard”
- Smart Notifications — Scheduled reminders with actionable buttons
(Screenshots will be added on this page in the future.)

Permissions & Battery Optimization
Why We Need Permissions
| Permission | Platform | Purpose |
|---|---|---|
| Notifications | Android & iOS | Study reminders and unlock alerts |
| Display over other apps | Android | Show flashcards as overlay |
| Accessibility Service | Android | Detect app launches for App Launch Trigger |
We only request permissions when you enable the relevant feature, never on first launch.
Keeping Background Features Alive (Android)
Some phone manufacturers (Samsung, Xiaomi, Huawei, etc.) aggressively kill background apps. To keep the unlock trigger working:
- Disable battery optimization for UnlockToLearn
- Follow device-specific instructions at DontKillMyApp.com
- Use the in-app help guide (Settings → Battery & Background)

Frequently Asked Questions (FAQ)
Does this work offline?
Yes! After importing your decks, everything works without an internet connection.
Will this drain my battery?
No. The app uses efficient background listeners and has minimal battery impact—comparable to receiving notifications from any other app.
Can I turn off the unlock trigger?
Absolutely. All features are optional and can be toggled in Settings.
Is my study data private?
100%. Everything stays on your device. We don’t have servers collecting your data. Optionally you can allow anonymous analytical data collection. The app will then collect data such as: your device & manufacturer, how long you stay on the app, how much you are using which feature, and so on, but nothing is related to your specific device ID or personal data.
Can I create my own flashcards?
Not yet, but this feature is planned! For now, you can create decks in ANKI (free, open-source) and import them.
What about spaced repetition?
We’re implementing SRS algorithms inspired by ANKI. Currently, cards you get wrong appear more frequently until you consistently get them right.
