Debugging a slow app usually means staring at one window and guessing what's happening in another. I wanted to see performance the same way I see the app — on the screen, in real time, so I built a small tool for React Native developers. react-native-sightline is a floating overlay that shows your app's performance right on the screen while you use it. You can see when things slow down, watch memory climb, and spot problems the moment they happen — without leaving the app. It takes one line to add and disappears completely when you ship to production. Open source, free to use. If you build React Native apps, I'd love your feedback. Link in comments ↓ #reactnative #mobiledev
Very cool! I’ve had an idea floating around for a RN app that I’m getting closer to starting - I’ll check this out when I do!
