4/5 stars

looked forever to find this!

I needed a conversion program that allowed calculations on the same screen, which I need and do every day when changing yields on recipes I cook (e.g. 1/4 cup ÷ 2 = how many tablespoons?). I couldn't find any other app that did this. I also really like the rolling wheels. In future updates would be helpful to hide or delete the units that I don't use. And I gave it 4 stars instead of 5 because the currencies should be listed by country, not by currency name. What if I need to know the value of dollars in New Caledonia, but I don't know the name of the New Caledonian currency?

5/5 stars

Easy, Useful, and Convenient

A well done app overall. Very useful and easy to use; truly an all-in-one app. for conversions.
