Best Calculator Ever This calculator is awesome, especially if you use RPN. I can't use a cell phone at work and so I use a dedicated scientific calculator there. I constantly find myself wishing that I had access to this calculator app instead. Just buy it.
Flawless I used the free version for a couple of years and decided to upgrade because I believe it's only fair to compensate the developers for such a good app. It's s fast, easy well designed and accurate calculator that leaves nothing to wish from a separate, dedicated device. If only all apps did their work the way this one does...
When it's the best, it's the best. This app has been the best spent money in all the play store. It's fast, accurate, stable, configurable and it is really the perfect calculator. And I can say the same for both algebraic and RPN mode. A must have if you need a scientific calculator! And unlike other apps, it's becoming better and better in a steady and sure way. Can I give 6 stars?
Worth every penny Hands down the best, most fully featured calculator available for android. The conversion feature is particularly useful which allows quick and easy conversion of temperature, speed, mass etc without the need for equations. A fine piece of software with an excellent developer behind it.
Samsung Note 3 This is 1 amazing calculator perfect for everyday use. But after update it is so awesome, keep up the great work, nothing beats this app. By far the best there is on Play Store.
My essential app I converted to RPN in college and started using this with my first smartphone. The free app is great but switched to paid version since I use it so often.
* Homescreen widget now supports RPN (follows app by default, can be changed in settings).
* New delta-percent function.
* Support for Android 6.0 Marshmallow.
Simple calculator with complete history (virtual tape, a.k.a. ticker tape style)
