AnkiHeat: Widgets for Anki

See your Anki study streak at a glance — as a heatmap or a clean streak counter on your home screen.

AnkiHeat lets you put heatmap and streak widgets on your Android home screen, powered by AnkiDroid you already use. Connect once, study like normal, and watch your progress fill in day by day — no need to open the app to know whether you're on a roll.

★ HEATMAP WIDGET
A colorful grid that fills in as you study, day by day — the same satisfying visual feedback power users love, right on your home screen. Three sizes: from a compact 4-week snapshot to a full 26-week view.

★ STREAK WIDGET
Prefer just the number? Drop a clean streak widget next to your heatmap. Same sizes, same customization, same tap-to-review — a clean count of consecutive days studied.

★ IMPORT YOUR EXISTING HISTORY
Already a veteran Anki power user? Don't start from zero. Import your past AnkiDroid review history and your widgets reflect your real history from day one.
AnkiDroid → 3-dot Menu → Export → Anki Collection Package (.colpkg) → Export.
Then AnkiHeat → Settings → Import Anki History → upload the .colpkg. All processing happens locally on your device.

★ WORKS WITH ANKIDROID
Reads your local AnkiDroid review data directly. No sync, no servers, no accounts. Tap the widget to jump straight into the deck you're tracking — less friction, more studying.

★ CUSTOMIZE FREELY
Pick any background, any accent color, any text color. Match your wallpaper, your mood, or your deck. One widget per deck — track German, Vocab, Kanji, Medical terms, whatever you're reviewing.

★ NO ADS. NO ACCOUNTS. NO TELEMETRY.
Everything stays on your phone. We hate ads as much as you do and will never add any. No sign-up, no data sent anywhere. Your study history is yours.

★ FREE TO START, PREMIUM WHEN YOU WANT
Both heatmap and streak widgets are free — all 3 sizes, automatic background updates, per-deck tracking, and tap-to-review, Anki history import, free forever. Premium is a one-time, lifetime in-app upgrade that unlocks the full customization options, unlimited widget designs, and all future Premium features. (No subscription — pay once, keep it forever.)

AnkiHeat is an independent project by a solo developer. Feature requests and feedback are welcome — I read every email and respond fast. Reach me at contact@ankiheat.app.

Note: AnkiHeat reads review data from AnkiDroid's local database and does not sync with Anki Desktop or AnkiWeb. Only reviews done on your Android device count toward your widgets (this problem may be solved in the future).
