Important:
In Standland, moving around more than one minute (more than 80 steps) per hour counts as one stand.
The app uses a combination of Stand Hours and Steps for overall tracking.
If Stand Hour data is available, it takes priority. If not, the app uses Steps to determine stand status.
With Steps, walking 80 steps or more in an hour counts as one stand.
Allow read permission in Apple's Health app.
Standland needs access to the Health app
If you allow the read permission and still there is no data, please open the Health app, and see if there is Steps data (or Stand Hours data if you use Apple Watch).
If the Health app is unstable, third party apps cannot access the data.
In that case, restarting your iPhone might fix the issue.
