Exactly, I've always wanted to have an app like that and have been following rescue time since a lot of years now and have aware about it being one of the pioneers in this space.

It's quite sad that apple conveniently are heavy handing them now that they have built in screen time. Users can't really complain cause this functionality is not kind of baked into the phone anyways.

It's impressive and hurtful at the same time, Apple has unprecedented amount of leverage over app developers and app developers should be careful not to cross Apple's path if they don't want their time to go waste.
