Having a dinner party and need to triple a recipe? Let’s say your recipe calls for 2 tablespoons plus 2 teaspoons of sugar. Using Convert, you can quickly find out that tripling it is a half cup and save yourself a lot of scooping!

I spy with my little eye… an all-new app icon! (The old one used just a bit too much wood for our environmentalist sensibilities.)

Swiss Army Converter

This tool can convert nearly everything to anything (within reason). I'm literally at a loss for words because it's just perfect. The only feature I could possibly ask for to make it easier would be voice recognition. Sometimes when I need an answer fast, I just ask google or Siri but this app has never let me down so I can't take away any stars for that.

Edit: I wish this would get updated so I can continue to use on iOS 11. Love the feel and usability of this app and it would be a shame to need to delete it after all these years.


Look pretty cool

I just bought this app cause I love camera+ and these folks deserve some money once in a while. I swear I don't know how they do it. That app just keeps getting better.
Anyway, back to this one.
It works very well and I like the interface. It doesn't appear that it's received any love recently as I am warned about iOS compatibility when I first launched it. Also data conversion needs some additional bases. I tend to work between base 10 and base 2 a lot. KB vs KiB.
Support for Petabyte scale would also be super useful.


Tremendous app.

This is the best conversion app I have ever seen. Over the years this app has been expanded to include more conversions. I hope that the developer can continue to keep this app compatible with the upcoming iOS updates, since Apple has flagged this app as being incompatible with future updates. It would be a great loss not to have this app available in the future. Again many thanks to the developer of this app, it is the most versatile I have ever seen.
