Forget the confusion.

Use a magic link (we email you a sign-in link) or continue with Google. On supported devices you may also see Apple sign-in. Open the link on the same device where you installed Recall. If the link expires, request a new one from the sign-in screen.

Buckets are subjects (Biology, Spanish, Interview prep). Notes are what you save inside a bucket — typed text, a link, a YouTube video, a PDF or an image. Any note you mark for spaced revision becomes a card in your reviews. A stack is today’s short review set, chosen for you by the scheduler.

After each card you say how it went: Forgot or Got it. Tap More if you want the finer grades, Hard and Easy. Cards you struggle with return sooner; cards you know well space out. Over time that flattens the forgetting curve — without cramming the night before.

Create a bucket for one subject you care about and put a few notes in it. When Today shows cards ready, start a review. Small and consistent beats huge and abandoned.

No. It means nothing is scheduled right now. Add new material, or wait for the next due window. “All caught up” is a feature, not a failure.

Each rating tells the scheduler how stable the memory felt. Forgot brings the card back soon. Got it is the normal pass. Under More, Hard shortens the next gap and Easy pushes it further out. Be honest — the scheduler only works if the ratings match reality. (Quiz flashcards use the four grades directly: Forgot, Hard, Good, Easy.)

Check three things: (1) OS notification permission is on, (2) Recall Drop / push is enabled in Settings, (3) you’re outside Quiet hours. Also confirm you have cards that can become due. Still silent? Email us with your device and OS version.

Yes — Settings → Recall Drop → Reminder style. Gentle waits for a larger batch, nudges at most a few times a day, and never re-nudges. Standard is the default: balanced, and it re-nudges after about two hours if a Drop is still unseen. Persistent keeps nudging in smaller batches. ASAO drops as soon as even one note is ready. Each style carries its own daily cap and its own minimum gap between Drops, so none of them can pile up.

Quiet hours are a window in which no Recall Drops are sent. Set a start and end time in Settings → Recall Drop → Quiet hours, or turn the window off entirely. Anything that becomes due during quiet hours simply waits until the window ends.

Yes. Spaced revision is a switch you control per note and per bucket, so Recall also works as a plain notes app for anything you just want to keep. Turn it off on a single note, or on a whole bucket, and nothing from it is scheduled.

Memory strength is how firmly you want to hold a subject. Raise it and cards come back more often, which means more reviews but a firmer hold; lower it and reviews get lighter and further apart. Set it once for your account, and override it per bucket where a subject needs a different grip.

Yes. Cached cards and a queued review flow keep you moving offline. When you reconnect, pending reviews sync. For grades, entitlements, and scheduling truth, the server wins if there’s a conflict.

That’s intentional. Recall never auto-refreshes mid-interaction and knocks you out of a review. When you’re ready, tap the nudge to load newer server data.

Sign in on the new device and give sync a moment. If a screen still looks stale, pull to refresh or use the updates nudge. Export from Settings if you want a local backup zip.

Aura works on the notes you have already saved rather than writing new material for you. It summarises a whole bucket, answers questions about your own material and shows which notes the answer came from, and suggests clearer rewrites of a note you’re editing. AI can be wrong — read what it gives you before you rely on it.

Aura searches your own notes first and cites the ones it used. If your notes don’t cover the question, it falls back on general knowledge rather than inventing a citation to a note you don’t have. It does not browse the web, so anything outside your notes comes from the model itself — treat it as a starting point, not a source.

Yes — open Tune Aura and tell it how you like answers: shorter, more examples, less hedging. Those preferences are stored for your account only and applied to your future answers. You can view or clear them at any time.

Check your network first — Aura needs a connection and won’t run offline. If a bucket has very little in it, answers will be thin, because Aura only has your notes to work from. Try again in a minute if a request stalls. Never paste passwords or confidential IDs into AI prompts.

We don’t use your study content to train our own foundation models. Aura sends what’s needed for the feature to AI processors. Details live in our Privacy Policy.

Recall is free and has no ads. There is currently no paywall anywhere in the app: the spaced-revision engine, your buckets and notes, Recall Drops, insights, and asking or summarising your notes with Aura are all open. A Premium plan will arrive later for the heavier things — the larger AI models and quiz. If a limit is ever in force on your account, the app shows it to you where it applies.

Quiz is still being finished, so it isn’t generally available yet. If you open it today you’ll see a short note saying the practice modes are on the way rather than a prompt to pay. We’ll turn it on properly once the modes are done.

Subscriptions are billed by Google Play or the App Store. Manage or cancel in that store’s subscription settings. Refunds follow the store’s policies.
