Your weight doesn't tell the whole story. You could lose fat and gain muscle and the scale won't budge. That's why photos matter — they show what's actually changing. Fit-Stitch pairs weight tracking with progress photos so you can see the full picture, not just a number. What it does: - Track your weight and take progress photos over time - Tag your snapshots and photos to organize your progress - Create side-by-side comparisons to spot changes you'd otherwise miss - Sync across your devices with iCloud — your data goes to your own private account, never ours - Lock the app with Face ID or Touch ID for extra privacy - Set reminders so you remember to track consistently Your data stays yours. Your photos and data live on your device. No accounts, no ads, no data collection. If you turn on iCloud sync, it goes to your own private iCloud — we never see it. Built by two indie devs, not a corporation. We're responsive, and we actually read our messages. If something's broken or you have an idea, reach out — we'd love to hear from you.

About

Single Standard

Features
Read full description

Built to treat firefighters like the professional athletes they are. Requires an individualized invite code from a participating department following an in-person movement screening to identify areas of increased injury risk. Tracks consistency with corrective exercise routines and overall movement progress over time, using your phone's camera with augmented reality to confirm each repetition was accurately performed rather than simply checked off. Sessions take ten minutes or less and are built to fit around a shift. Session video is processed on your device and never uploaded or stored. This app supports an exercise program prescribed by a licensed physical therapist. It does not diagnose, treat, or provide medical advice. Talk to your clinician before starting any exercise program, and stop if you experience pain.
