Apple Watch heart rate trends unavailable in Health app on iPhone

on my health app on my iPhone it says trend unavailable for walking heart rate average and resting heart rate even though I had my watch for 4 almost 5 months

Even after 4–5 months, these readings may say “Trend Unavailable” if your Apple Watch hasn’t collected enough suitable background heart-rate measurements. Wearing the watch regularly helps, but it doesn’t guarantee that every metric will be available.


Try these checks:

  1. On your watch, open Settings -> Privacy & Security ->Health -> Heart Rate and make sure heart-rate tracking is enabled.
  2. Wear your watch snugly during the day so it can collect reliable readings.
  3. On your iPhone, open Health -> Browse -> Heart -> Resting Heart Rate and Walking Heart Rate Average to see whether individual readings are being recorded.


If there are no readings, check More info: Monitor your heart rate with Apple Watch.
