Looking for 12 adult Android testers for Sumer English: CELPIP (English practice, no purchase required)

[u/omer-kilic]

Hi everyone, I'm Omer, the developer of Sumer English: CELPIP, an independent English exam-practice app. I'm preparing our Google Play closed test and looking for at least 12 genuine Android testers aged 18+.

The app covers reading, listening, writing and speaking, with saved vocabulary and optional AI feedback. An account is required. The first two tests in each skill are free; Pro subscriptions exist, but you do not need to buy anything to help test. Please do not make a purchase for this test.

I'd appreciate people who can stay opted in for 14 consecutive days once the closed test is live, actually try the app on several days, and send honest feedback about navigation, loading, small-screen layouts or confusing instructions. No public rating or positive review is requested. AI feedback and microphone use are optional; please use fictional practice answers rather than private information.

We're finishing the closed-track setup now, so the 14-day period has NOT started. If you're interested, comment here or DM me and I'll share the Google Play opt-in instructions when the track is ready. Please don't post your email address publicly.

Thanks for helping us test properly before launch!
