Ratings and Reviews
The converter app I have been waiting for ..
This is the most comprehensive app on the app store. I was using four different apps to make various conversions, this replaces them all. Calculator is nice addition. It makes it easy to use converted numbers for further calculation. As far as I know no other app does it. Widgets are cool as well. App allows you to change decimal points on each tap. That is kind of cool. It makes it look uncluttered but also allows you to view accurate numbers when needed. Clever! Overall navigation takes little time to get used to, but help and on screen notations will make it easier. Worth every penny.
Interface revels in being different, but it's difficult to use in practice. As mentioned by others, the calculator widget is hopelessly inaccurate. Waste of a purchase.
Crashes upon opening
I want a refund this app worked flawlessly until the iOS 8.3 update so please fix
With Family Sharing set up, up to six family members can use this app.
