How long do you want to spend waiting


This app was fantastic when I first loaded it. However, at some point they decided to overload it with ads. I don't have 5 minutes to sit around and watch ads before I get my conversions done. I was literally solving problems while this app was still showing me crap I was not interested in. Can you skip them? Nope. So skip this app instead.

Awful in app ads

Aspiring polyglot

The tool is handy, but the ads will occasionally make the app completely unusable. There will be multiple full screen ads in succession that prevent you from continuing until you either click the ad or find the small hidden X out button. And all the ads are for trashy pay to play game apps. Deleting it and not looking back.

Too many ads


0 Stars....This used to work fine when you only had to watch 1 ad, now you have to watch multiple ads and sometimes close the app and reopen to get out of the ads. Look for a different unit converter.
