Trusted by 250,000+ users across 170+ countries, Sonar helps you cut through the noise across sleep, recovery, stress, activity, and nutrition - so you can focus on what actually matters. Sonar isn't just another health tracker. It merges the latest medical, sports and data science with AI engines that continuously surface subtle shifts and patterns across millions of data points, helping you know when to push, when to pause, and where to focus next. FEATURES: Personalized intelligence Sonar AI is a personal health agent grounded in the data across your wearables, health apps, and connected devices. Ask questions, understand changes in your scores, and get answers that reflect your actual data - not generic advice. Sonar AI also remembers personal context you give it like training goals, travel, or new routines, and factors it into how it interprets your data over time. Sync everything Fragmented data means missed signals. Connect Apple Watch, Garmin, Oura, Fitbit, Strava, Withings, MyFitnessPal, Peloton and many more. Daily scores and guidance Recovery, Strain, Sleep, Stress, Energy, and Nutrition scores help you understand your day at a glance, with practical guidance to improve. Correlations & comparisons See how any two metrics relate over time.

Compare up to six metrics at once, or focus the view on a single category like activity, sleep, or recovery. 24/7 vitals monitoring Track trends in HRV, resting heart rate, respiratory rate, blood oxygen, body temperature, and more, and get notified when values move outside your typical range.

Tap Start tracking once and Afoot records your day on its own. It can tell whether you’re walking, running, cycling, or driving. You don’t need an account. Your history stays on your iPhone. ■ Automatic recording You don’t have to keep the app open. If Afoot gets an activity wrong, you can fix it on the timeline. ■ Workouts Choose cycling, walk/run, or hiking and set a goal by distance, time, or destination. Afoot reads out your progress as you go. When you finish, you’ll see your pace (speed for cycling) and estimated calories. ■ Place alerts Save home or work to pause recording while you’re there. Save a place you’re heading to, and Afoot notifies you how far you have left as you get close. ■ Collections Put the activities from a trip, or a route you take often, on one map. Photos and videos you took along the way show up where you took them. You can export a collection as an image or a video. ■ Maps and history Every route has speed and elevation graphs. You can jump to any past day from the calendar. You can also import and export GPX files. ■ Privacy There are no ads, and no tracking or analytics code. Afoot looks through your photos on your iPhone and uploads nothing. You can lock the app with Face ID. ■ Battery Using GPS in the background can drain your battery faster.
