I have multiple calculator apps on all my devices and I kept coming back to this one, becuase of it's unique ability to let you copy answers and enter those numbers into other problems with a simple swipe and tap. This app is so easy to use and to navigate and is aestheticaly pleasing too. Having four calculators in one comes in more handy more often than I would have thought. Though, it's more fun to use on the iPhone and iPod, I ended up keeping it in my dock on my MacBook Air and iMac. Very good investment.

Take four calculators, squish them together, and there you have it... Solve in a nutshell. I understand that the app works but it would be cool to see Solve maintained. I use it atleast once everyday and would hate to loose it sue to a a Mac update.

This has the most features for a free calculator on a mac that I’ve seen! It takes a minute or two to figure out how to use it.
