Free to download: https://apps.apple.com/app/id6759611784 Page: https://speedometerproapp.com/features/heart-rate-while-driving Last updated: 2026-11-10 Odo reads the heart rate your watch, band or chest strap saved to Apple Health and puts it on each trip, next to your speed. It works on trips you’ve already recorded too. ## Why it matters Speed and distance tell you what the road did. Heart rate tells you what it did to you. Seeing the two together shows which stretches were the most demanding, such as heavy traffic, a hard stop or a long ride in the wind, so you can plan breaks and pick calmer routes. ## On every trip Turn on Health in Settings and each trip shows the heart rate recorded while you drove or rode. - Average, peak and lowest heart rate - A small heart rate chart across the trip - Your heart rate at your top-speed moment - How your heart rate changed after braking ## Heart rate and speed, together When your device records heart rate often, Odo charts it against your speed and breaks it down in a full analysis. - Heart Rate & Speed chart for the whole trip - Heart rate during each acceleration and braking event - Heart rate by speed range, and stopped versus moving - Key moments of the trip, with an About This Data section that says how often readings were taken ## From the device you already wear Any watch, band or chest strap that saves heart rate to Apple Health works, not only Apple Watch. - Outside a workout, most watches measure every few minutes, so most trips show average and peak - Start a workout on your watch before you set off, or wear a chest strap, to get the full chart - Works on trips you recorded before you turned it on ## Private by design Odo reads Health data on your iPhone when you open a trip, and nothing else. - Read-only: Odo never writes to Apple Health - Not copied, stored, synced or uploaded - Turn it off any time in Settings → Health ## How to set it up 1. **Turn it on**: In Odo, open Settings → Health and turn on Show Health Data on Trips. 2. **Allow Heart Rate**: In the Apple Health prompt, allow Odo to read Heart Rate. 3. **Open a trip**: Heart rate appears on the trip’s details, including trips you recorded earlier. Note: Odo isn’t a medical device. Heart rate is shown as recorded by your device, and readings can be sparse or wrong. ## Questions and answers ### Can I see my heart rate while driving on iPhone? Yes, after the trip. Odo reads the heart rate your watch, band or chest strap saved to Apple Health and shows it on each trip with your average, peak and lowest heart rate, next to your speed. ### Do I need an Apple Watch? No. Any device that saves heart rate to Apple Health works, including other watches, fitness bands and chest straps. ### Why do I only see an average and peak, not a chart? Outside a workout, most watches measure heart rate only every few minutes. To see heart rate charted with speed, start a workout on your watch before you set off, or wear a chest strap. ### Does Odo store my health data? No. Odo reads it from Apple Health on your iPhone when you open a trip. It doesn’t copy, store, sync or upload it, and never writes to Apple Health. ### Is it useful for motorcycle riders? Yes. Riders can see how their heart rate rose with speed, after hard braking or on a long ride, and wear a chest strap or run a workout on their watch for the full heart rate and speed chart. ## Related - [Noise level on your trips](https://speedometerproapp.com/features/driving-noise-level): How loud each drive or ride was, in decibels, measured by Apple Watch and shown next to your speed. - [For riders](https://speedometerproapp.com/features/motorcycle-and-bike): Motorcycles, scooters, bicycles and e-bikes: ride tracking, gauges and routing built for two wheels. - [Trip Insights](https://speedometerproapp.com/features/trip-insights): A short summary of every drive, written on your iPhone.
