It is a collection of 16 memory games, including the chimp test, n-back, digit span, memory palace, and card recall. Pick a daily goal of 1, 3, or 5 games, or play full challenges from the Games tab. The app works offline and does not require an account.

Choose 1, 3, or 5 games for the day. Completed games are saved, so you can finish the goal across several visits. An unfinished game starts again from the beginning. Once you start, today's goal stays fixed; changes to the goal apply the next day.

Numbers appear briefly, then hide. Tap them back in the correct order. It is the same idea as the chimp test and digit span, and it is called 数字隐身 in Chinese. Other games cover memory palace, card pairs, sequences, and more.

The free version shows ads. Remove Ads is a one-time in-app purchase. Open Profile → Remove Ads → Restore Purchases and sign in with the same Apple ID you used for the purchase.

If it still does not appear, email us with the purchase date and your App Store country or region. Do not send your Apple ID password.

In the EEA/UK, a Google consent form may appear on first launch. You can change your choice later in Profile → Privacy → Ad privacy options.

If you do not see that row, your region may not require the form. The app does not request App Tracking Transparency permission and does not access the IDFA.

Use Profile → Daily Reminder and choose a time. iOS will ask for notification permission. If notifications are blocked, enable them in iOS Settings → Notifications → Chimp Test.

Progress, records, settings, and the Remove Ads entitlement are stored locally on your device. There is no account and no cloud sync.

Deleting the app removes that local data. Reinstalling starts fresh; we cannot restore gameplay progress from a server.

Daily results and full free-play records are kept separately, and sound-cue and visual-cue records are also separate. That is intentional: the daily version uses a shorter flow, while free play uses the full game.

The app runs on iPhone and iPad with iOS 17 or later, and is available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, French, and Spanish. Some ads and the consent form need a network connection.
