Sonar Fit
AI-Powered Rep Tracking
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Train smarter. Move better. Track every rep effortlessly.
Sonar Fit turns your Apple Watch and AirPods Pro into intelligent workout companions, using built-in motion sensors and AI to automatically count reps, track sets, and optimize your rest — so you can focus on lifting, not logging.
WHAT IS SONAR FIT
Sonar Fit is a next-generation strength training app designed for iPhone and Apple Watch. It uses real-time motion data and machine learning to automatically detect your reps, sets, and rest periods — hands-free.
Whether you’re doing squats, deadlifts, presses, or curls, Sonar Fit recognizes your movements and keeps track of your workout without needing to tap your watch or phone. It even uses your AirPods Pro (2nd Gen or newer) for head-motion tracking if you’re not wearing your watch.
KEY FEATURES
- Automatic Rep Counting – No manual input required. Your Watch or AirPods detect each clean rep.
- Real-Time Feedback – Instantly see your progress on Watch or iPhone during a workout.
- Hands-Free Rest Timer – Rest starts automatically when your set ends.
- Smart Set Tracking – View reps, sets, and history without lifting a finger.
- Watch and AirPods Support – Use either device, or both. You choose.
WHO IT’S FOR
Sonar Fit is built for people who lift:
- In home gyms or commercial gyms
- Without a training partner
- Who want to avoid tapping screens mid-set
- Who care about form, focus, and tracking their progress over time
WHY SONAR FIT IS DIFFERENT
Unlike traditional fitness trackers or rep counters, Sonar Fit doesn’t rely on you to manually press buttons or enter numbers. Instead, it uses sensor data from your Apple Watch or AirPods Pro to recognise reps and intelligently guide your rest.
We believe in frictionless training. No distractions. No guesswork. Just better sessions.
