The app keeps showing the HealthKit permission error.
Try restarting your iPhone, then reopen the app. If it still doesn't work, go to Settings → Health → Data Access & Devices → TrendMyFitness, and check that all categories are enabled.
My new workout has no heart rate ring.
This happens when the Apple Watch hasn't finished syncing HR data to your iPhone. Pull down on the Workouts list to refresh — the ring usually fills in within a minute.
How do I reset my HR zones?
Open Settings → Heart Rate Zones → adjust the sliders. Changes save automatically and sync via iCloud.
TrendMyFitness reads workouts and health data from Apple Health, processes it on your device, and never sends anything to a server. Your settings sync through your personal iCloud only. We don't have an account system, a database, or any way to identify you.
