Super convenient

Great unit converter app.

This is a great converter app that is extremely useful for quick conversions, and is very easy to use. It does have a good amount of conversions, but if it had a money converter added it would be perfect. If you want a converter app and don’t need a money converter, I would recommend that you get this.

It’s great that you only pay once for the app, and it’s not a cash greedy monthly or yearly subscription!
