Google Play Closed Testing Prep Kit: An illustrated guide to preparing your first closed test

Hi Product Hunt! I'm Seonghyeon, the independent creator of this kit. While preparing my app, PhotoFit, for Google Play, I documented the decisions and checks involved in getting ready for closed testing. I turned that experience into an illustrated learning resource for first-time app creators. The kit includes: - A 113-page guide and 8 task cards - A companion video of about 9 minutes, with original diagrams and AI-generated narration - A CSV checker and 5 working templates English and Korean editions are available, along with a bilingual bundle. You can preview sample pages and a short video clip on the product page. This covers preparation for closed testing. It does not provide testers, submission services, or approval guarantees, and it is not affiliated with Google. Which part of preparing your first closed test has been the most confusing? I'd welcome your questions and feedback.
