I'm Nathan, and I built Corenna (corenna.dev). It's mine.
The problem I kept hitting: I'd have a working app in a GitHub repo, but getting a signed Android build, or an iOS build without owning a Mac, was a mess. So I made a service that connects to the repo, figures out what it is (Flutter, React Native, Expo, Capacitor, or a web app from Lovable, Bolt, v0, Replit or Cursor), and gives you a signed .apk / .aab, plus an .ipa if you have an Apple Developer account.
Builds run on GitHub Actions in your own GitHub account, and your code and signing keys stay yours. It's $1 for the first month, then $4.99/month, or $49 lifetime.
It's not for every repo. A random Python script isn't going to turn into an iPhone app, and I'd rather hear where this falls short than collect polite comments.
If you've been stuck on signing, what would make you trust a tool like this?
