How can we help?

NEURA: Brain Training is an iPhone app built around one short session a day — 20 reasoning tasks, about five minutes, generated fresh so you never get the same board twice. Train daily and your Focus Index shows you where your attention, recall and speed are going.

No. Onboarding is a short series of screens introducing NEURA, then straight into your first session — there is no test or questionnaire to sit through first. Your Focus Index is built from the sessions you actually train.

Your first session is free — no subscription, no payment details. After that, training continues with NEURA Premium, which starts with a 3-day free trial.

NEURA Premium opens with a 3-day free trial. When the trial ends it becomes an auto-renewing subscription billed through your Apple ID, unless you cancel before it renews.

Subscriptions are managed by Apple, not by us. On your iPhone, open Settings → Apple ID → Subscriptions → NEURA and tap Cancel Subscription. You keep access until the end of the period you have already paid for.

One training score across the cognitive domains you train — attention, recall, speed, reasoning. It opens after your third completed session, once there is enough of your own data to plot, and then shows your 14-day trend. It is not an IQ score, and it is not a diagnostic or medical measurement.

We collect only what the app needs to run and to show you your own progress. What we collect, why, and who it is shared with is spelled out in the Privacy Policy. Read the Privacy Policy

Both live inside the app: open You → settings and choose to export or delete your data. You can also ask us instead — use the form above, or email support@neurabrain.app — and we will confirm once it is done.
