Photocalculia.aia (3.2 KB) - I have made a camera app. But it isn’t just any ordinary app. It requires pure mathematical skill to just use it! Let’s say you click on the shutter button. A multiplication problem appears! If you solve it correctly and click on the verify button, you get access to the camera; but when you don’t, it reminds you that your problem is wrong. There might be a stray text box, but just ignore it; and click on OK. And that’s how my camera app works! 
Here's a better look at your app, with a little editorial assistance (I renamed Button1 and Button2 to make the blocks clearer)
