Training zones. Your heart rate now shows the zone you are in, from Zone 1 to Zone 5, and the whole display takes that zone's colour. Set your maximum heart rate and adjust where each zone starts in Settings. Heart rate variability. Chest straps report the interval between beats, and Heart Rate now reads it. Your HRV appears next to the battery level once enough beats have been seen, and is saved with every session. Sessions are kept. Each measurement is saved automatically and listed under the share button with its duration, average, maximum and HRV. Export any of them as a CSV with real timestamps. A clearer screen. The graph has been redrawn, settings have moved behind a gear in the corner, and the app now walks you through pairing a monitor the first time you use it. The screen stays awake while you are measuring, and the layout now fits iPad properly.
Send your Heart Rate to the Health app from your Bluetooth LE Heart Rate Monitor. In addition to seeing your heart rate in-app, the app will continue to run in the background, adding your heart rate to the Health app once a minute. You can also easily export a CSV of your heart rate over time. Note that Fitbit devices won't work with this app, due to them locking down their Bluetooth communications. This app has no ads, and doesn't sell (or even track) your usage to anyone, ever.
