I've been tracking my bar path to improve that J-curve to the lower chest, this kind of curve is better to prevent shoulders injury imo and also it made me lift more weight. im trying to keep my elbows in a 45 degree instead of 90 degree
I released an app (FormVision) a week ago and I realized that I blindly followed the same playbook everyone was doing it and in some point it didnt math my product. I was copying characteristics from others apps that went viral, like the long onboarding (17 steps) that acts as a funnel, the hard paywall, that sensation of creating the problem to the user in the funnel to then solve it with the app... but after a week of releasing it I realized that my app is totally different, the people that wants to use it already know "the problem" or at least they already know why they are downloading it, so I got 35 downloads but nobody finished the onboarding, thats why now I changed it to simplify it and in the onboarding only show the main features working and explaining why are so accurate, I even trained my own ML model to have the best engine but nobody was even getting to it.
So after a week I re-did it almost completely:
- took out lot of half finished features
- kept only the one best feature,
- cut the onboarding in to 5 pages explaining only how the features work,
- added a weekly cheaper plan
and lastly I re wrote all the apple store view and changes the screenshots to show the main feature working, this last change was bcs I saw the apps of the competition and realize that my description was too long that nobody will ever read it, same with the promo text and I didnt had localizations, so...
Lets see how this week goes !
any recommendations ? something that I may be forgetting ?
I built FormVision, an iOS app that films your barbell lift and traces the exact path the bar travels, plus rep speed and a form score. Solo dev. Apple approved it last Friday. It couldn't actually take money until Sunday, because I'd created the subscription products but never submitted them for review, the first subscription group has to ship attached to a version, and mine wasn't. The app was live and the purchase button silently did nothing. That was bug number one.
Here's the honest scoreboard so far:
- €105.88 spent on TikTok ads
- 52,451 impressions, 790 clicks, CTR 1.34% (fine for the category)
- 0 attributed installs
- $0 revenue
I spent most of a day convinced the product was the problem. Then I opened my own App Store page from a browser instead of from App Store Connect, and saw this: "Requires iOS 26.5 or later." My deployment target had silently inherited my Mac's iOS version. Around 21% of active iPhones are below that, plus everyone sitting on 26.0–26.4. All of them saw a greyed-out Get button. Xcode never warned me. The build compiled, the archive validated, Apple approved it and shipped it. Bug number two, same shape as the first: something configured, nothing verified. The part that stings: I ran typechecks against iOS 17 all week. The data was in front of me. I just never looked at the one field that mattered.
What I'd tell anyone shipping their first app:
Read your public App Store page from a logged-out browser after every release. Not the ASC preview — the page a stranger sees. Check the iOS requirement, the age rating, and whether your screenshots still show features you removed.
Check the generated Info.plist, not your project settings. `plutil -p YourApp.app/Info.plist` inside the .xcarchive. MinimumOSVersion, UIDeviceFamily, orientations. Three of those have bitten me now.
Ads amplify your funnel, they don't fix it. My CTR was healthy the whole time. People wanted in. The door was locked.
Two things I got right, for balance:
I refused to score what the camera can't measure reliably. Most form apps grade everything and are confidently wrong about half of it. Mine tells you when the framing is bad instead of inventing a number.
The fix is in review. I have no idea whether conversion will move and I want to be careful not to blame everything on the iOS gate, because the numbers don't support that. Adjusting for the ~21% who were blocked, my listing was still converting at roughly 5% against a 25-30% App Store average. So there's a 5x hole the bug doesn't explain.
App is FormVision on the App Store if you lift and want to see what your bar actually does. First analysis is free, everything runs on-device, nothing gets uploaded.
Happy to answer anything about the on-device CV side, I ended up training my own plate detector because the off-the-shelf optical tracker kept locking onto plates on the floor in busy gyms.
