Installing it
- Tap Download the APK above. Your browser will warn you about downloading this kind of file — that warning appears for every APK, not just ours. Choose Download anyway.
- Open the downloaded file. Android will ask whether to allow installs from your browser; tap Settings and turn on Allow from this source, then go back.
- Tap Install. If Play Protect offers to scan the app, let it — then tap Install anyway.
Keeping it up to date
Because this build didn't come from the Play Store, Android won't update it for you. Most improvements arrive on their own the next time you open the app, but bigger releases need a fresh download — come back to this page and install over the top. Your account and progress stay where they are.
Trouble installing?
If the install fails, check you have around 300 MB free and that you're on Android 8 or newer. Still stuck — email nihao@ai-chinese.app and tell us your phone model and Android version.
