Awesome awesomeeee 👌🏾

It's sleek and easy to work with! Sometimes I just open it to just look at it, and now I'm even more excited to solve my chemistry problems. The apple calculator is quite annoying because I have to rotate it here and there and the buttons even become tinier. Not fun. But this one even supports fractions, and even though it took me a while to find out how to enter the denominator, I would choose it over the apple calculator. But if also love if you could add conversion? It would be awesome!! Thanks 😊😊

Powerful yet simple. I love this calc.

This is a powerful calculator with a simple interface. Its not not only good for every day use, but is also good for accounting, advanced maths and more (hence the name Calculator+). I've been using it for years and one of the things that I love the most is that the developer is always improving the app and keeping it stable during years. I love it, very useful, can be used even for algebra and complex maths.

SAT Tutor loves this calculator!!

I've been using this calculator for a few years now and I love everything about it. It is incredibly handy and reliable to pull out when working with students on high level SAT and ACT test math problems. Nothing ever pops up to try to advertise or sell anything to me--in fact, sometimes I forget it's even an app!!! It just feels like someone embedded a TI inside my phone. Thank you!!! --Karen
