Official Description

I've had some people contact me saying that some of my apps are too cheap, and they would like a chance to donate some more. Well, this is just that chance.

This app does nothing. It doesn't even show up in your laucher.

There are 3 donate apps: https://play.google.com/store/apps/details?id=com.joaomgcd.donate10
https://play.google.com/store/apps/details?id=com.joaomgcd.donate5
https://play.google.com/store/apps/details?id=com.joaomgcd.donate1

To uninstall go to Android Settings->Apps->Donate. Just don't uninstall before 24 hours after you purchased it or else you will be refunded.

Thank you for all your support! :)
