PhotoDistance
A proof-of-concept mobile app: photograph a scene, tap an object, get an estimated distance to it.
PhotoDistance is a proof of concept I built to answer a simple question: could I build a mobile app entirely in Replit? The idea - take a photo, tap a point or object in it, and get back an estimated distance to that thing.
How it works
Snap a photo (or pick one from your library), drop a pin on the object you care about, and the app analyses depth cues - perspective, scale, and known reference sizes - to estimate the distance, along with a confidence level. It was built far enough to be genuinely functional as a proof of concept.
Built with
Made with Expo (React Native) and developed in Replit - it runs on a real iPhone through the Expo Go app by scanning a QR code from the project. More an experiment in the build pipeline (idea → mobile app → running on a phone) than a finished product.
