Health App Dashboard Empty on the iPhone? It’s a Quick Fix
The iOS Health app can keep track of your movement, steps, and fitness throughout the day, and it works really great with the new iPhones… most of the time, at least. But sometimes you can open Health app and rather than seeing a chart of your fitness activity for that day, week, or month, you’ll see a blank dashboard, as if all of your prior activity, steps, and mileage has been erased.
Not to worry, your activity logs are not missing, and all of your health data is still on the iPhone*.
