Getting help

Email [email protected]. We aim to reply within two working days. Telling us your iPhone model and iOS version saves a round trip.

Common questions

Is there an Android version?

No, and there is no plan for one. Attu is an iPhone app and there is no web version.

Does it work without a signal?

Yes. The whole app works offline, including the session it has prescribed for today. Your log lives on your device and syncs when a connection is available, so a gym with no reception changes nothing.

What happens to my data if I cancel?

Nothing is deleted. Your history stays readable and exportable after a subscription lapses. Nothing you have logged is ever rewritten or removed by us.

How do I cancel?

Subscriptions are managed by Apple. Open Settings on your iPhone, tap your name, then Subscriptions, and cancel there. Cancelling takes effect at the end of the period you have already paid for.

How do I delete my account and everything in it?

Ask us at [email protected] and we will delete it. Deletion is real: your account and every record attached to it are removed, not flagged as hidden.

What is the coach?

An AI system. It can be wrong, and it is not medical advice. The engine underneath it is not an AI — it is arithmetic, and the reasoning behind every number is shown in the app.

Something is wrong with a number the app gave me

Tell us. Open the recommendation, tap through to the reasoning, and send us a screenshot at [email protected]. Every prescription records what it was based on, which usually makes it quick to find.
