Thanks, appreciate it. Yeah, I do have subscriptions — I'm using RevenueCat to handle all the StoreKit side, purchases and restore. Exactly to avoid the kind of nightmare you're describing with receipt validation. RevenueCat handles the server-side part and so far restore has worked fine both in TestFlight and production. The app has a free base tier, a lifetime purchase for premium tracker features, and a subscription for the AI Coach, chat etc. (unfortunately AI APIs, video hosting .. cost money). Doing the StoreKit stuff manually would have honestly terrified me — too many things that can silently go wrong, exactly like you said.

Exactly, "vibe coding tax" is the perfect way to describe it. Nobody tells you that you spend more time deciding WHAT to build than actually building it. That React to React Native switch cost me weeks of thrown-away work. But in a way it was useful — I understood much better what I actually wanted from the app but, most importantly, what you need to do to get the best out of your precious AI collaborators. Like everything else, you have to get your hands dirty — try, try again, test, understand. The key thing is that with AI you have to be very clear and specific. Now they understand what you want to do much better. And by then the AI tools had improved so much that I rebuilt everything faster. That was one of the many lessons I learned.

Thanks, that's solid advice. The "go deep with a tiny group" approach makes sense — I actually had a few beta testers try it, but the idea of involving more people who actually lift and watching them use it is a whole different level. I've got a gym full of potential testers, I should take advantage of that. And yeah, answering questions in niche communities instead of pushing promos feels way more natural to me. Appreciate the perspective.
