Totally hear you! So there is a way to do this, but it takes a minute to set up: you can exclude all “good” apps you don’t want to count by setting them as Neutral. Here’s how:
You can tap on any app and edit wether you think this app is Productive or Distracting. Hit Save, and your score and chart will update.
Productive: Apps that help your Focus
Distracting: Apps that hurt your Focus.
Neutral: Apps that neither hurt not help your focus. They are not counted towards your screen time. You can use this for example for apps you use in the background like Google Maps or audio like Spotify.
