About VocaPurr
VocaPurr is a vocabulary learning app for Android phones and tablets. You create your own word lists – called “pools” in VocaPurr – in any language pair you like, and share them with friends. Progress is managed in flashcard boxes using the proven Leitner system (spaced repetition): words you answer correctly move back and come up less often, mistakes return to the front. Your practice goes exactly where it is needed.
VocaPurr is offline-first: learning works without an internet connection, the data on your device sits in an encrypted database, and syncing with the server runs in the background as soon as you are back online. There are no ads in the app, no advertising ID and no personalised advertising. Only a single event is measured – whether the first learning round was completed – and you can switch even that off.
Everything you need to learn vocabulary
Leitner boxes
2 to 10 compartments, with an adjustable promotion rule and review schedule. Every answer is saved instantly, not at the end of the session.
Four practice modes
Typing with typo tolerance, self-assessment with reveal, multiple choice and AI-generated gap-fill sentences.
Online challenge
Duel a friend: buzzer, round timer and live score.
Share pools
Give confirmed friends read or write access to your word lists. Friend code and QR code included.
Streaks & rewards
A daily streak from ten answers, plus coins and short cat clips as rewards for milestones.
Privacy by design
Encrypted local database, tokens in the Android keystore, no location data, no advertising ID. Only one measurement event (first learning round), can be switched off. Delete your account in the app at any time.
Make it look the way you like
VocaPurr comes in 15 looks – from calm and tidy to pixel blocks and neon. Two themes are included; the other 13 you unlock in the shop with coins you earn while learning. A theme restyles the whole app, and twelve of them even bring their own buzzer cat to the duel.
Every screenshot shows the same buzzer duel against the practice partner, with the bot leading by two points. In Power Aura and Storm Zone the cat powers up when it leads.
Who is VocaPurr for?
For children learning alongside their parents, for school and university students, language course participants and anyone who wants to build their own vocabulary systematically. Learning works from age 4. The social features – friends, shared pools and the online challenge – are unlocked for under-16s only once a parent or guardian has given consent.
Security & privacy
VocaPurr processes only the data needed to run the service. Push notifications go through Firebase Cloud Messaging (Google) with minimal content; the AI gap-fill sentences are generated by an external language-model provider, with no personal data in the prompt. Details are in the privacy policy.
