Dear Android Central community,

I'd like to introduce my app "Learn 4 Fun"!

Learn 4 Fun works like a screen lock. Before accessing the apps or games on the phone or tablet, your kids have to solve some math exercises first and are rewarded with play time.

Once time is up, access will be locked and the exercise screen appears again.

Learn 4 Fun is not a kids mode! Access to apps and internet is not restricted.

Download:
Learn 4 Fun on Google Play

Selectable mathematical operations:
★ Addition
★ Subtraction
★ Multiplication
★ Division
★ Unit conversions
★ Number patterns

Advanced features:
★ Stats
★ Phone is always accessible (e.g. for emergency calls)
★ Password protected parents settings
★ Incorrectly solved exercises are repeated more often
★ Adjustable number range for additions and subtractions
★ Select specific series for multiplications and division
★ Adjustable play time reward
★ Adjustable maximum play time

Unit conversions:
★ Length
★ Mass (weight)
★ Liquids
★ Imperial or metric units

Google Play Games (optional):
★ Unlock Achievments
★ Leaderboards for every category

Permissions:
In order to work properly, Learn 4 Fun needs to check if another app is currently running
in foreground. On devices running Android 5.0+, this feature requires usage access.

Nice app, I like the design.
But I dont understand, why its need some odd permission (I never see it before and I really dont know what exactlly I allow). And second thing - why is there possibility to open phone call from app?

Thanks for your feedback!

Regarding permissions:

L4F needs to check if another app than itself is running in foreground to decide whether the countdown should be running or paused.
For the whitelist feature, it even needs to check which app is running in foreground. From Android Lollipop and above, this requires usage access.

Best Regards

Thanks for replay, actually I think it could work quite good without it - I understand that you want to check and control everything, but if I want cheat time counting, I think I could find some possibility anyway - in my opinion it's just for user if want it or not. But I understand it that you want it like that. And one last thing what I forgot to mention - its count some weird time - everytime when I set result its add me one minute to play time (even if it was much lower). Just for information - I try it without that permision...

Very good. I was thinking of something like this the other day. Good to know it now exists.
