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.

Verdict
The clearest difference is price: TrainersKit at Free against Fit's $4.99. TrainersKit also leads on update cadence (every 9 days vs every 2 months) and review sentiment (100% vs 79%). Fit's advantage is ratings volume (330 vs 2). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
