Two places to learn. One progress.
Organise your cards in the app. Study on the device without the distractions of a smartphone.
The app
Create decks and cards, import from CSV, study with spaced repetition and track your progress – for iOS and Android.
The Calligra device
A dedicated study device with an e-ink display and Bluetooth. Decks are loaded from the app onto the device. Black and white, calm, focused. (In development.)
Your account
With an account, your decks and cards are available on multiple devices.
For school, university and anyone who wants to stay on track.
School students
Vocabulary, formulas, dates: small, regular study sessions instead of cramming before the test.
University students
Review terms and definitions throughout the semester. Bring existing card collections into the app via CSV import.
Parents
The Calligra device is for studying – no games, chats or notifications. A calm place for your child’s study time.
Three steps to studying.
Create a deck
Write cards with a front and a back yourself or import them from CSV.
Load it onto the device
Connect the device via Bluetooth and transfer the deck with one tap.
Study
Flip the card, choose “Right” or “Wrong” – Calligra schedules the reviews for you.
Honestly: we’re still on our way.
The app is being built and tested, and the Calligra device is in development. That is why we state neither prices nor dates. If you’d like to follow along, join the waitlist.
