Recall
Beautiful, fast flashcards that remember for you.
A calm, modern flashcard app built on the FSRS spaced-repetition scheduler. Import your Anki .apkg, CSV, or Quizlet decks on-device, study with a tap-to-reveal loop and four predicted-interval grades, and watch your retention in a real stats dashboard. Fully offline, no account, no ads.
Recall offers an auto-renewing subscription. Payment is charged to your App Store or Google Play account; it renews automatically unless cancelled at least 24 hours before the period ends, and you can manage or cancel anytime in your account settings. Terms and Privacy Policy.

What you get
Built for exactly this — and nothing you don't need.
FSRS spaced repetition
a full, modern scheduler (not crippled on the free tier): reveal a card, then grade it Again / Hard / Good / Easy, with the predicted next interval shown on each button before you tap.
On-device import (the wedge)
Anki .apkg files (decks, notes & embedded media), CSV files, and pasted Quizlet exports: everything is parsed locally, with no account and nothing uploaded.
Three card types
Basic, Basic + Reverse, and Cloze: with a live cloze preview that shows the blanked question and revealed answer as you type.
Distraction-free study loop
progress bar, tap-to-reveal, one-tap grading, and undo of your last grade (which fully reverts the card's FSRS memory).
Stats dashboard
a retention ring, GitHub-style review heatmap, due-cards forecast bar chart, current streak, retention change vs. the prior window, and retention broken down by subject.
Image & audio cards (Recall Pro)
attach a photo or audio clip to a card, shown and playable under the answer during study.
Custom FSRS retention targets (Recall Pro)
set your desired retention percentage (80–97%) and the scheduler adapts; free users stay at the default 90%.
Light / Dark / System appearance, configurable daily limits (new cards per day, max reviews per day), haptics on grade, and local due-card reminders.
Fully offline and private
all decks, reviews, and imports live on-device only: no cross-device sync, no sign-in, and no ads, ever. Pro adds full CSV export of your decks.

A note from the studio
“I studied for exams on Anki for years and loved the science but never the app. Quizlet felt like a social network with a paywall. I wanted something quiet, fast, and affordable — that respected the work you already put into building your decks.”
Questions
The honest answers.
Can I import my Anki decks?
Yes. Tap Import, pick your .apkg file, and Recall loads all your cards and embedded images on-device. No internet connection required and no lock-in — your decks stay yours.
What is FSRS and why does it matter?
FSRS (Free Spaced Repetition Scheduler) is the modern open-source algorithm that predicts forgetting more accurately than the classic SM-2 algorithm Anki defaulted to for 15 years. You see four rating buttons — Again, Hard, Good, Easy — and Recall shows the predicted next review interval for each so you can make an informed choice.
Does my data sync across devices?
Recall is fully on-device — your decks and review history live on the device you're using. No account is required, and nothing leaves your device.
Is it really cheaper than Anki?
Yes. AnkiMobile is $24.99 on iOS with no free study tier. Recall Pro is $19.99 lifetime and includes a free tier of up to 3 decks and 300 cards before you need to upgrade.
Do you show ads?
Never. Recall has no ads on any tier. Recall Pro is a fair trade — a small one-time or annual payment keeps the lights on without selling your attention or your data.
Do I need to create an account?
No account, email, or sign-up required. Recall works fully offline the moment you open it.
All your decks, cards, review history, scheduling state, and imported media are stored locally on your device. There is no Lumen Labs server copy — nothing leaves your device.
