Getting started

Why do I need my own API key?

Recall talks to Google Gemini (or OpenAI) in real time. Rather than reselling that capacity with a subscription on top, the app uses your key, so usage bills to your own account at cost — usually a few cents per session.

Get a free key at Google AI Studio, then paste it into Settings → Voice model → API key and tap Test connection.

Your key is stored in your device's Keychain. It is sent with each request and never stored on our server.

It says I have no study plan.

Go to the Plan tab and set a goal and your current level. Everything else — which scenarios you get, how hard they are, what comes back for review — is decided from those two things, so the app will not start a session without them.

During a session

I can't hear the coach, or it can't hear me.

Wear headphones. Without them the coach's voice feeds back into the microphone and the echo canceller has to fight it.

If the microphone level bar under the speaking meter does not move while you talk, the app is not capturing audio. Check Settings → Recall → Microphone on your phone. If the bar moves but nothing happens, check that your ringer/call volume is up — voice sessions use the call volume, not the media volume.

The coach interrupted me / did not correct me.

It is deliberate. The coach recasts your mistakes naturally in its next reply and logs them silently — interrupting to correct is the fastest way to stop someone from speaking. Explicit corrections come at the end, in the debrief.

Can I pause?

Yes. Pausing stops the microphone upload and the timer; the connection stays open, so resuming is instant. Anything you say while paused is not uploaded and does not count toward your speaking time.

Memory and review

Why does the same word keep coming back?

Because you have not produced it unprompted yet. Review is scheduled on what you can say, not on what you have heard — an item you only recognise stays in the queue.
