[FREE] Do you want to stop yourself from sending drunk texts/posts?

Hi everyone!

My app is called “Block my apps” and it basically does what its name suggests: blocks the apps you want until you’re sober enough to correctly solve three mathematical equations! These equations are simple additions/subtractions, for example: 7 + 3 + 2 + 8. It’s ideal for drunk people (in order to not drunk text/post stuff on social media), and for when people lend children their phones (so they don’t do something on accident).
I would love to get some feedback, and any opinions such as whether it’s user friendly or not are very welcome, as well as if the UI looks good or not, etc.
