Play memory and solve different challenges: Numbers, Letters & more
About this app
This memory is a learning experience for children aged 4+. Through different challenges, they can learn counting, numerics and reading.
The different game modes and adjustable levels of difficulty allow the child to play with and without guidance. This game is also available as a web version at http://memory.quelltext.eu for you to try out.
These modes can be played in three different difficulties, with six, twelve or twentyfour cards: - counting dots and finding the numbers - big and small letters - adding numbers - subtracting numbers
If you and your child like to play an additional game mode, please do not hesitate to contact us. If you are a developer or want to become one, you can extend the game with the modes you would like to see in it. The internal API and documentation make creating these extensions easy. The game is an open-source software under AGPL so that you are allowed to copy, distribute and modify it.
Code of honor: This game is child and privacy friendly: - no advertisement - no communication over the Internet - source is open and publicly disclosed - no in-app puchases

Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be eu.quelltext.memory is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.6 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Learning Memory first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Learning Memory, and a listing is removed when the evidence for it stops holding up.
