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.

Just better sessions. DEVICE COMPATIBILITY - Apple Watch Series 6 or newer is recommended for best motion accuracy. - AirPods Pro (2nd Gen or newer) & AirPods Max are supported for head motion tracking. - iPhone required to install the Watch app. - Requires iOS 17+ and watchOS 10+.

Unlock Earth turns your real GPS activities into a permanent collection of places you've actually moved through. Connect Strava once. From then on, every qualifying run, ride, hike or ski is automatically checked against real municipality boundaries — sourced from official government and international open-data providers, not approximations. Cover enough distance inside a municipality's real boundary in one activity, and it's yours: permanently unlocked, even if you later delete the activity from Strava. HOW IT WORKS • Connect your Strava account — no manual map or import steps, ever. • Your history syncs automatically, including in the background while the app is closed. • Meet the distance rule inside a real boundary, and that place unlocks for good. • Be the first person ever to unlock a municipality, and claim a World First. WHAT YOU GET • A permanent, personal collection of every place you've earned • Dozens of achievements, from your first unlock to conquering an entire country • Real municipality boundaries, independently verified against authoritative sources — not guesses • Full support for running, hiking, cycling, gravel, mountain biking, cross-country skiing and backcountry skiing COVERAGE More than 150 countries across Europe, the Americas, Asia, Africa and Oceania, including the USA (county level, the only US tier with complete, gap-free coverage), Canada, Mexico, Brazil, Japan, South Korea, Australia and New Zealand. Some boundary sets are older or coarser, and a few countries (for example India, China and Russia) are not available yet. The Coverage screen in the app lists every country, its status and the reason. PRIVACY Unlock Earth never sells your data. Your GPS routes are used only to determine what you've unlocked. Delete your account and all your data, permanently, any time from the app.

Verdict
The clearest difference is in-app purchases: Unlock Earth at none against Sonar Fit's 2. Unlock Earth also leads on update cadence (every 5 days vs every 2 weeks) and iOS requirement (15.1 vs 17.6). On price, ads and device support there is nothing between them.
