In the category of "good clean fun" --

Squid Sudoku

My other game:

MushRoom Bounce
https://play.google.com/store/apps/details?id=com.twosquidgames.mushroombounce

Both are FREE by the way.

You can play with colored Squids, or regular numbers. The game has every feature you could want in a Sudoku game too.
I just updated it, for the first time in 5 years. I had neglected the game, so many newer phones couldn't even find the game in the Google Play Store.

[St Giles]

How about an app that locks out the internet and non essential apps after a certain period of active use until a rosary is prayed so the app can hear it, or a button is pressed that says "I love my phone more than God"

Not a perfect idea, but you get the point. This is not an attack at your attempt to bring people good clean fun.
