FormTwin - The daily health app built around your 3D body twin

by•
FormTwin is a daily health hub built around an interactive 3D body twin—tap any muscle to see how to train it, and after a workout the muscles you hit light up. It also does workout plans, nutrition and macro logging, and habits, with a Today tab that gives a morning recap of your whole day. Start a workout or log food from Control Center. Built entirely on iOS 26, it works without an account, and there are no ads and no third-party tracking—your data stays on your device.

Hey Product Hunt 👋 I'm Mustafa, and I built FormTwin solo. Most fitness apps hand you a calorie number and a list of exercises. I wanted to actually see my body — so FormTwin is built around an interactive 3D anatomy twin. Tap any muscle and it shows you how to train it; log a workout and you watch the muscles you hit light up. Today's update turns it into a full daily hub: • A new Today tab — a morning recap of yesterday, then your whole day (habits, workout, food) in one place • Habits, reminders, alarms and notes built right in • Control Center controls — start a workout or log food from the Lock Screen • Snap & share — turn a meal or workout into a branded card It's built entirely on iOS 26 (Liquid Glass, AlarmKit, Live Activities, Control Center controls), works fully without an account, and has no ads and no third-party tracking — your health data stays on your device. I'd genuinely love your feedback: what would make this an app you open every day? 📲
