It is my friend.

Pet. F. Sep 2, 2014     

Really like this app and upgraded to Pro. Also like the large display and the way it works the percentages. Unfortunately since my phone updated to Kitkat the large display has vanished and have sent 3 emails to developer but got no reply. If they can fix this I will give 5 stars.

A. G. u. Mar 7, 2014     

Update:Auto calculate does not work with 4.4.2. Really useful, user friendly. The best I've used. Auto answers as we type is nice to have. The large view area is good and the font auto adjust from large to small size as the equation/ calculation gets longer. The author of this app is great too. Reads and responds quickly to emails and requests.

Rod. F. Jul 14, 2016     

This calculator has always been my favorite, except for the fact that it makes very loud clicks every time and doesn't even respects the silent mode on my phone. Please fix that or add an option to mute the clicks, and start getting 5 star reviews every time.

BT. S. Mar 12, 2015     

This calcu is exactly what I wanted. Neither too simple nor too complicated but very easy and useful to use. Thanks~~

Rut. T. Apr 27, 2017     

An amazing calculator which does everything you need for simple calculations. One major floor though... the clicking sound. Without this it would be a guaranteed 5 star. I keep downloading it hoping they have fixed it, keep being disappointed :-(

Jen. E. May 15, 2017     

I absolutely positively hate this app because it is absolutely nothing to help me with my homework and it's supposed to help you with homework so I don't get why doesn't help... So definitely do not get this app if you struggle with math and you want help

Ces. C. Jun 7, 2017     

Simple and easy to use, and for everyone that hates the loud clicking sound, you can access the app preferences and disabled it by pressing and holding the Recents button.

Che. B. Apr 16, 2017     

Love this calculator but the loud clicking sound is super annoying. Looks like a lot of users of this calculator find this a problem too so maybe this issue needs to be fixed.
