I've noticed that Present very significantly underreports the amount of time I’m using my phone.
For example, it doesn't count the time I'm using incognito mode on safari, which is a bit of a problem because that means Present underreports my screen time, allowing me to inadvertently "cheat," which I really don't like. Also, if you download an app, use it, and then delete it, the time you were using it doesn’t get reported. Those are just two of the “bugs” I’ve found, but there certainly are more.
I was really excited about BePresent, but if it doesn’t correctly track my time, it just can’t work as intended. I mean, just today I’ve used my phone for more than twice the amount of time than it thinks I’ve used. I know this because A) the built in screen time app says I’ve been using my phone for 2.5 hours and B) when you’re actively reading on your phone for two straight hours, you know it’s been two straight hours because of clocks, but present says I’ve used my phone for a little over an hour.
If they fixed these issues, I’d happily use it. All it needs to do is accurately track what the screen time iOS app says, but it can’t do that, apparently.
