Frequently asked questions

Can I use the app without signing up?

Yes. You can start as soon as you open the app. Every game and every record feature works without creating an email address or password.

Will I lose my records if I change devices?

An account with no email registered is stored only on that device. If you delete the app or change devices, it cannot be recovered. If you register an email in Settings, you can sign in on a new device with “I already have an account” and bring your records with you.

Can several people share one tablet?

Yes. Each person makes their own account, and you switch by tapping a name on the screen. Scores and records are kept separately for each person.

How much of my record can my family see?

If you are in the same circle, scores and streaks are visible to each other. Your detailed records by cognitive area are visible to nobody by default. Only someone you have specifically chosen can see them, and you can make them private again at any time.

My invitation link went to the wrong person.

An invitation link can be used only once and expires after 14 days. If nobody has used it yet, you can simply leave it and it will expire on its own, and a link that has already been used cannot be used again. To invite someone else, send a new link from the Family screen.

Someone who has already joined, however, cannot be removed by anyone else. Circles in this app are built so that no one holds authority over anyone else, so leaving is something each person does for themselves at Family > Leave circle. If someone joined who you did not intend, please create a new circle.

I want to erase my account and records completely.

You can delete them yourself at Settings > Delete account. Your account and activity records are deleted together and cannot be restored. If other family members remain in a circle you created, that circle stays.

Does it work without an internet connection?

Yes. You can play as normal, and records are saved on the device and synchronised automatically once you are connected again.

The text is too small.

You can turn on Larger text and Bold text in Settings. If the screen feels too bright, try Dark as well.

Can this app tell me whether I have dementia?

No. This app is a tool for training and for keeping a record of activity, and it is not a medical device. Scores are not a diagnosis or a test result. If you are worried about your health, please speak to a medical professional.

Accessibility

Larger text, bold text, high contrast, and reduced motion can all be turned on in Settings. If anything is difficult to use, tell us at the email above and we will act on it.
