A1 Builders Calculator for Android

Purchased this app to calculate if a frame is square. The results are not understandable.

The only thing free about this app is the download.

I downloaded this app and the first calculator I tried to use required an in-app purchase of $1.99. I made the purchase which also promised to remove the ads. It unlocked the calculator and removed the small banner ad at the bottom. However, it did not remove the annoying pop-up video ads which seem to pop up about every 3rd calculation and you must wait several seconds before closing them. If you're going to pay for a calculator of this type just buy one without ads. I wasted $1.99.

The app froze up on first use. When I opened it back up I realized you couldn't use over half the features. The features you could use caused the app to crash. So, question, why buy it if the free version doesn't work?

App it self is not bad except, it have very little things to do, but it's okay, but what I hate this this app makers for? Right after I've installed this app, very first try, free version, as soon as I opened up, message pop out, (upgrade this app and remove adds), and option {Cancel or Okay} so who would like to be interrupted in the middle of estimate progress, if you hit cancel, it will cancel, and you won't use app, of course I hit "Okay" after couple seconds of upgrading, and of course upgrade is $1.99 first thing app did, it CRASHES!!!!!!!!! YEAH!!! CRASHES!!!. So I did restart app again, start my building material estimate, as soon as I typed up numbers and hit = button, instead of giving me result Dumb ADD POP OUT!!! Yeah ADD!!. And after paying 2 bucks and having adds with crashes, on my app?! That's why I hate this thing. But science I've paid 2 dollars I'll keep this for a while.
