Show HN: I made a weight-loss app using OpenAI APIs(apps.apple.com) Hey HN, wanted to show you my weekend project (several weekends actually). A few months back I started experimenting with LLMs as a way to estimate calories/macros and give useful feedback. The results were good enough that I felt like something was there. I wanted to shed a few pounds so I built out a web app for myself. A few friends tried it and everyone said "this needs to be a native app". So I converted the Rails app to just be an API backend and built an iOS app in SwiftUI. It just got approved in the (US) app store last week. https://apps.apple.com/us/app/fatgpt-ai-weight-loss-coach/id... Feature-wise it's pretty simple compared to MFP or Noom. But I've been logging my food every day for a while now and am down 12 pounds. It's been really fun to build and I'm trying to release a new version every week. Happy to hear any feedback or answer questions. |
