Do you still have the code for this app? I was thinking of making something similar.

It's been offline since like 2014, so probably wouldn't even work on newer Android versions. But we did have competition, so it seems like there should be equivalent functionality today.

Have a look at "Family Link". It is not perfect, but it can limit usage of apps and the whole device to specific times (and more).

I have used family link, it's kind of all or nothing deal. I want the ability to define block schedules.

I want to be able to put some sort of delay when opening time wasting website so that it is not as addictive.
