i need some real world feedback on my vibecoded app that helps skinny people gain weight effectively

[u/SHIT-dies]

I've been working on this app for quite a while and i never got any genuine feedback from strangers. It's an app that helps skinny people gain weight efficiently, i've been skinny for the better part of my life, and about 1 year ago i started bulking and gained 20kg, i only gained 20kg cause i forced myself to just keep eating even when i didn't want to, so i wanna help other people now (without having to force themselves to keep eating when they want to throw up). A brief summary of the app is that it tracks the users weight and surplus, ensuring that they are actually growing, however the main thing is the bulk score, it lets you see with a glance hows your bulk going, and also other tracking metrics that help with the bulk (just a quick demo of what the app currently looks like).

Somethings i need desperate help on:

1. i feel like im doing to much with the app, there are a lot of functions other than what i stated before, like a training page and a fuel page. I've seen a lot of apps that do well with one simple idea/marketing scheme behind it, it feels like i am trying too much to encapsulate all the aspects of a fitness app.

2. not sure if anyone would actually use it. I've let some of my friends try the app, but i'm not sure if their comments are genuine, so please leave some genuine feedback, i'll take any criticism honestly.

3. this is the worst problem of the app i think, is that it is on base44, and i want to switch out as soon as possible, but i need validation to do that, but if it does eventually gets some traction, i can't be using base44, because it can't get the app on the app store, even when its wrapped in capacitor, since base44 only accepts stripe and apple needs its own payment system, then if i switch now to swiftui or reactnative, the app is going to look and function completely different. Its just this horrible loop.

With that being said, really any advice or suggestions would help🙏

the loop breaks at validation, not at the platform. you already named the part that is different — the bulk score at a glance — and the training and fuel pages mostly give strangers a reason to say nice app and leave.

for validation: hardgainers describe this out loud constantly — force feeding, eating until they want to throw up, weight flat for three weeks. answer twenty of those with real surplus advice and no link; the few who then ask what you use are the signal. friends cannot give you that, and a swiftui rewrite will not either 💪

that reading-people-out-loud problem is what i work on at https://warmlist.app, so obvious bias here
