TestFlight beta · Spanish/English

Help me finish my app.

I'm a solo developer in Chicago. BiloChat is an iPhone app that teaches Spanish or English through the texting you already do, with an AI coach that catches mistakes before you hit send.

It works — but I've only really tested it on myself, which is the worst possible sample. Two weeks of real use and honest feedback from you is worth more than another month of me guessing.

What testing involves

  • iPhone required. The beta runs on iOS 18 (iPhone XS or newer, updated). Installed via Apple's TestFlight — free, official, nothing sketchy.
  • Free, the whole way through. Everything the app will eventually charge for is unlocked for testers, for the whole beta.
  • Real use, not marathon sessions. Open the app on at least 4 different days each week — a few minutes each time is genuinely fine. Send messages, try the practice quizzes.
  • One short form per week. About 10 minutes each, at the end of week 1 and week 2. Thoughtful answers, including negative ones.
  • Honesty over politeness. "This is confusing" and "I'd never use this" are far more useful to me than praise.

Apply to test

Takes about 3 minutes. I'm selecting ~12 testers for a mix of levels and native languages — thoughtful answers to the two short-text questions are what get you picked. Selected testers get a TestFlight invite by email.

1. Do you have an iPhone that can run iOS 18? (iPhone XS or newer, updated)
2. Which describes you? (check all that apply)
3. Roughly what's your level in your second language?
6. Realistically, how many days a week would you open a language app?
7. Up for a 15-minute video call at the end? (Optional)

TestFlight invites go to your Apple ID email — if that's different, add it below.

Application received — I'll be in touch by email within a few days. ¡Gracias! 🎉

The honest fine print: during the beta I review usage stats and may read messages sent inside the test build to verify activity; treat beta messages as practice text, not private correspondence. This is product testing and feedback — it is not connected to App Store ratings or reviews in any way.
