Deckwell: Spaced Repetition

Deckwell is a spaced-repetition flashcard app that schedules your reviews for you, so your study time goes to the cards you're about to forget. It's made for NEET, JEE, UPSC and MBBS preparation, for medical and nursing students, and for anyone learning a language. There's no account and no ads, and your decks stay on your phone.

MODERN SCHEDULING (FSRS)
• Built on FSRS, the open-source spaced-repetition scheduler: every card gets its own memory model
• Choose how much you want to remember (90% by default), or set a memory target per deck
• The next interval on every answer button, learning steps, daily limits per deck, bury siblings and undo
• No daily caps and no subscription

YOUR DAY AT A GLANCE
The Today card shows how many cards are due across all your decks, about how long they'll take at your own pace, your progress and your streak. One tap studies every deck.

BRING YOUR DECKS
• Import .apkg and .colpkg deck packages, including modern exports, with subdecks, cloze cards, note types, tags, flags, images and audio
• Keep your progress: past reviews come along, your stats and streak carry over, and each card's memory is rebuilt from its history
• Import a newer version of a shared deck and the notes you haven't edited are updated
• Or import a CSV or TSV file from Google Sheets or Excel

EVERY CARD TYPE YOU NEED
• Basic and reversed cards
• Cloze deletions with hints, several deletions per card and nested clozes
• Type-in answers with a letter-by-letter comparison
• Image occlusion: hide the labels on a diagram, X-ray or map and recall them one by one. Study shared occlusion decks or draw boxes on your own pictures
• Math and chemistry notation: fractions, roots, Greek letters, H₂SO₄, reaction arrows
• Images from your gallery or camera, bold, italic and underline, and a preview of each card before you save it

A STUDY SCREEN FOR DAILY USE
• Card flip, tap to reveal, swipe right for Good and left for Again
• Again / Hard / Good / Easy, with the next interval on each
• Live counts, cards left, flags, and card info with the full review history
• Audio cards, and text-to-speech in English, Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam and more, using your phone's voices
• A session summary with your recall, streak and when the next review is due

STUDY YOUR WAY
Custom study when you want more: learn extra new cards today, review ahead before an exam, drill the cards you forgot, or study any tag or search. Practice mode lets you cram without changing your schedule.

STAY ORGANISED
Nested decks (Biology › Genetics), tags, flags and search: tag:anatomy, deck:"Polity", is:due, flag:red. Select many cards to suspend, move, tag, flag, reset or delete them at once.

SEE YOUR PROGRESS
• A full-year review heatmap and day streak
• Your recall over the last 30 days, with young and mature cards side by side
• Answer buttons, difficulty, intervals and the time of day you remember best
• A forecast of the cards due over the next 30 days

ONE DAILY REMINDER
One study reminder a day at the time you pick, with how many cards are due. It's scheduled on your phone.

START IN SECONDS
Two original sample decks are included, Indian Constitution basics and Bones of the upper limb, so you can try a session right away.

PRIVATE AND SAFE BY DESIGN
No account, no ads, no analytics and no tracking. Deckwell makes no network requests of its own: your decks, images and review history stay on your phone, and everything works offline. Automatic daily snapshots of your collection can be restored from Settings. Back up your whole collection as a zip file to Google Drive or email whenever you like, and restore it on a new phone. Check media finds missing images and frees space from unused ones.

COMFORTABLE FOR EVERYONE
Light and dark themes, large text support, screen-reader labels throughout, and support for the system's Remove animations setting.
