I want to make a pedometer, but when the application is closed, the step counting stops. Is there a possibility to count steps in the background.
To your keep app running in background you need to use 2 extensions
For running app in background
com.puravidaapps.TaifunNotification.aix (8.8 KB)
Set this block as you want to running your app in background
Also you need to turn of battery optimization for your app otherwise your app will close after few minute,
Here is the extension to ask the Battery optimization turn off
com.puravidaapps.TaifunBatteryOptimization.aix (6.7 KB)
If this is helpful for you don’t forget to mark it solution!! 
I’m trying to make a comeback
