Acuo — short games for attention, memory and reaction speed

Acuo is an Android app with short games for attention, memory, reaction speed and reasoning. You play in brief sessions, and every answer you give is kept, so what the app tells you rests on your own data.

An honest measurement alongside

Some games also work as measurement tasks.

We show a measurement estimate only when there’s enough data behind it, and always alongside its range.

When a change can’t be told apart from ordinary day-to-day variation, the app says so instead of calling it a change.

What we don’t promise

We don’t promise you’ll become smarter, more attentive or faster outside these games.

The games train skill at the tasks themselves.

Results reflect task performance in the app and are not a diagnosis or medical assessment.

Offline first

You can play offline. Results are sent once you’re back online.

Your data

There are no ads and no third-party analytics in the app. An account is optional. What the app sends, where it is stored and how to delete it is described in the privacy policy. To delete your account and data, see Delete account.

Availability

Acuo is being prepared for release on Google Play.
