Hi, thank you for this detailed feedback. I'll see what I can do. Meanwhile, you can try adding one of the conflicting apps on the home screen. That way you won't have to search for it. Thank you for using Olauncher.
We have made some major improvements in the screen time calculations. It shouldn't be wildly different from phone screen time anymore. You can turn on the 'Screen time' feature from the Olauncher settings. If you face any issue, please let us know. Thank you and have a wonderful day!
