Block distracting apps until you review a spaced-repetition flashcard
About this app
ProcrastiLearn turns mindless app-opening into vocabulary practice. Choose which apps you tend to open out of habit — social media, browsers, games — and whenever you launch one, a full-screen flashcard overlay appears. Reveal the translation, rate how well you remembered it, and the app you wanted opens immediately. No subscription, no ads, no accounts.
HOW IT WORKS
Pick the apps you want to gate in the Apps tab. From that point on, opening any of those apps shows a flashcard first. You rate your answer (Again / Hard / Good / Easy) and the FSRS spaced-repetition algorithm schedules the next review automatically. Daily caps prevent you from being overwhelmed.
If you tend to lose track of time once you're inside a gated app, the optional recurring reminder has you covered: set an interval (e.g. every 10 minutes) and the overlay reappears as long as you stay in that app, turning each lingering session into extra review reps.
VOCABULARY
Add words manually or use the optional AI translation feature: paste a word, tap Generate, and the app drafts a translation using OpenAI. The AI prompt is fully editable so you can control tone, context, or target language.
You can also import existing Anki decks (.apkg files) to get started immediately with a vocabulary set you already trust.
LANGUAGE SUPPORT
The app currently works best with English-Russian vocabulary (that pair is the default in the AI prompt), but any language pair works — just edit the prompt in Settings to match your target language. Support for additional language pairs with dedicated UI will be added in future releases, especially based on user requests in github issues or via email.
PRIVACY
All data — vocabulary, blocked apps list, review history, and settings — is stored entirely on your device. There are no analytics, no crash reporters, and no advertising SDKs. The only outbound network traffic is the optional OpenAI API call you initiate by tapping Generate, using your own API key entered in Settings.
PERMISSIONS
Accessibility Service: used solely to detect which app is currently in the foreground so ProcrastiLearn knows when to show the overlay. The service does not read screen content, keystrokes, or any other input.
Display Over Other Apps: required to draw the flashcard overlay on top of the gated app.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.procrastilearn.app is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.1.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall ProcrastiLearn first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of ProcrastiLearn, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets ProcrastiLearn do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
