Why it fades

When your face or fingerprint unlocks your phone, you almost never type your passcode anymore — and the memory quietly fades.

It happens with every secret you don't use often. A bank card PIN you rarely punch in. The safe combination you set last spring. Your main email password, saved and autofilled for months. The day you actually need one of them, the memory isn't there.

KeyRote is the opposite of a vault you can never recite. It's a memory trainer, not a password manager or a place to store logins: each secret becomes a flashcard, and a few seconds of recall now and then keep it sharp. The secret lives where it belongs — in your head — not only in your keychain.

Adaptive practice

It knows when you've learned it — so it stops bugging you.

Every review is self-graded: again, good, or easy. Get a secret right and KeyRote pushes the next review further out — a day, then several, then weeks, then months. Hesitate, and it comes back sooner.

The better you know something, the less often it asks. No fixed daily grind, no busywork on things you've already nailed.

Nothing due today means nothing due today.

Graduated hints

Stuck? Get just enough of a nudge.

Recall help isn't all-or-nothing. When a secret won't come, you choose how much help you want — and stop the moment it clicks. You're never stuck choosing between remembering perfectly and giving up and showing everything.

Hint
A small clue, like the first part — just enough to jog your memory.
Input check
Type your guess; KeyRote confirms whether it's right — without showing it.
Progress check
See how much of it you've got so far, without revealing the rest.
Reveal
Show the whole thing when you'd rather just see it and move on.

Built to be private

Your secrets stay yours.

KeyRote is built so the things you're memorizing stay on your iPhone, under your control.

On your device only

Everything is stored on your iPhone — never uploaded to a server or synced to the cloud.

Locked to you

Your secrets sit behind your phone's own device authentication — your face, fingerprint, or passcode.

Your choice, per secret

Keep a secret recoverable so hints can help — or store it one-way, where nobody, not even KeyRote, can ever reveal it.
