Help us launch Koilingua on Android
Google requires real testers before a new app can go live on the Play Store. Join our closed testing program — try the app and unlock free Premium as a thank-you.
Why we will need testers
To publish a new Android app, Google Play asks developers to run a closed testing period with enough active testers. Your participation will help Koilingua pass this step and ship the official Android release.
As a tester you will install the pre-release build from Google Play, explore Southeast Asian language learning features, and share feedback if something breaks or feels unclear.
What you will get
Every participant will be rewarded for helping us launch. Active testers can unlock an even bigger Premium gift.
3 months of Premium free
When applications open, fill out the form and join the closed test to receive 3 months of Koilingua Premium free during the testing period.
1 year of Premium free
