About

Deckmere Flashcards

Features
Read full description

Deckmere is a flashcard app for your own study material. Bring it in from Anki, a spreadsheet or your notes, review it with FSRS spaced repetition, and check the answers you feel sure about. Buy once for the authoring tools. No subscription or account. BRING YOUR MATERIAL • Import Anki packages (.apkg and .colpkg, older and current exports) with formatting, tags, subdecks, images and audio. Basic, reversed and cloze notes come across; anything Deckmere cannot show is named before you import. • Keep your Anki progress or start fresh, your choice. Importing the same deck again updates what changed and keeps your own edits. • Import CSV or TSV files and pasted two-column lists, with a preview of the real cards before anything is saved. • Write cards yourself, or try the sample deck. • Every deck gets a picture that follows its name, or one you choose. REVIEW WITH FSRS • Today shows what is due, a short session of ten cards or a few minutes, and a clear rest when nothing is due. • Reveal the answer, then choose Again, Hard, Good or Easy and see each next interval before you choose. • Undo the last grade. Hear a side read aloud with your device's voices in the deck's language. CHECK WHAT YOU ARE SURE ABOUT • A self-check takes up to 10 cards: type an answer and choose your confidence before you see the card. • Mark your answers yourself and retry the mistakes, confident ones first. Your FSRS schedule is not changed. YOUR DATA, YOUR FILES • Back up everything to one file and restore it on your iPhone or iPad. Restoring only adds what is missing. • Export to Anki, or export card text as CSV or TSV. • Your library stays on your device and can sync between your Apple devices through your own iCloud. FREE, AND PRO ONCE • Free, with no cap and no time limit: cards and decks, review, the self-check, import, export and backup, and five generated cards a day. • Pro: add images, audio, cloze and image occlusion; make cards from PDF pages and photos; keep a saved mistake list and self-check history; plan toward a goal date; edit many cards at once; draft cards without a daily limit. • Card drafting runs on your device, with Apple's on-device model where available and a rules-based helper elsewhere. The screen says which one drafted. • One purchase, Family Sharing included. Restore Purchases restores it with the store account used to buy it; purchases on Apple and Google are separate.
