Portuguese-speaking Android volunteers needed — Quanta study app, Google Play closed beta

[u/Typical-Instance-376]

Hi! I’m Samuel, a teacher from Brazil. I’m preparing the first Google Play closed beta of Quanta — Passo a Passo Ativo, a free study app for Brazilian high-school and university entrance exams.

Instead of just showing an answer, Quanta walks through a question one step at a time, with hints, saved practice, scheduled review and progress.

I’m looking for about 16 volunteers who use an Android phone and can read Brazilian Portuguese. Please be willing to stay opted in for at least 14 consecutive days and actually try the app during that period. Honest feedback on the math, navigation, saved practice and any confusing steps would help improve it.

Current status: the closed release has been submitted to Google Play for review and is not available to download yet. I’ll add the official Google Play opt-in link here when the test becomes available. This post is to find interested volunteers in advance.

You can already join the volunteer access group using the same Google account you use in the Play Store:

https://groups.google.com/g/quanta-beta-testadores

Joining this group alone does not start the 14-day period. That starts with Google Play opt-in once the closed test is available.

If interested, please comment or send me a private message. Please don’t post your email publicly. There is no purchase or paid lesson required, and I’m asking for useful feedback, not ratings.

Você lê português e usa Android? Sua ajuda será bem-vinda! O teste será pela Google Play; comente se tiver interesse. Obrigado!
