Very nice to use, and very similar in layout to the Casio Scientific calculators from 1980 to 2010, but with the addition of 5 or 6 extra independent memories, and an undo key! A big improvement on so many of the orher "micky mouse" calculator apps available. Adverts do pop up occasionally after pressing the equals key, but they can be swiftly dismissed by pressing the back key.

it's a good calculator. I had uninstalled it because of the fullscreen ads in the middle of calculations. I just learned from the developers that these ads are only three times per day and I think I can live with that.. I really like the style (calculation on the top - result at the bottom). I just reinstalled it!

The best calculator app I have used so far. But in the recent update there's a problem. While pressing and holding the 'DEL' key to delete multiple digits, the settings menu pops up. Settings menu should only appear while pressing SHIFT+ DEL keys. Anyway still 5 stars for this highly functional calculator.

Practically unusable, because of the ads! We understand that 'free' apps show occasional ads, but not in the middle of the operation. The ads are full screen, and such that you cannot get rid of. You have to wait a minute until you can close them. You forget what you originality wanted to calculate. 'Only 3 per day', but I olny open the app 3 times per day. So every time I have to waste a minute on ads. Doesn't make sense to me.

Very fast and reliable calculator, touch screen is a big plus. The help menu is a great guide and the conversion features is very helpful. Ads can be annoying but they don't pop up offline. One thing it is missing is a button to find the 'n' th root of a number, other than that it has pretty much everything. Edit: it does have an 'n' th root! I was blind

Best for engineering students. However if you want to improve it then provide facility to make it floating over another app. In addition to calculator function it can be improved by providing another facilities like area, volume, weight calculator. Thank you.
