Calculator easy of use with more in depth options if you need it, possible history of all operations saved, a good visual with a good size main characters. A reliable & functional free app. Existing ads at the bottom not taking over.. can have an ads free version in paying if really you can’t stand it.
Was great, ads now insufferable and collecting your data

I’ve used this for many years, since having an iPad. It works fine for the limited needs I have. Regarding ads, there were none. When they appeared, they were static at the bottom of the screen - fine. Then this changed to a full screen pop up ad - not welcome but acceptable. Now there are multiple ads, one after another and one today had no obvious way of closing it - ridiculous, the sort of stuff I would p expect from a dodgy warez type site. I was also asked to accept data being passed to other companies - really? An annually renewable subscription to remove them? … no thanks. Uninstalled and I recommend you avoid, there are ad free alternatives. Impala seem to reply to negative reviews as though people are highlighting new issues which they will consider. Nonsense! They know what they’re doing and do it anyway! I understand that funds are needed to maintain an app but it’s now unusable. The decent score is based on the app being great in its earlier days … sort the scores by most recent or most critical!

This calculator works fabulously on an iPad as it is the size of an adding machine but has the versatility of an intelligent calculator with features such as showing all the stages of your calculation. There are probably many features I haven’t even found yet but I am so pleased to have found it.
Now perfect !

Easy to use and with Memory functions I wanted. Not having a % key on the main screen was a PAIN but it’s now been moved back there. Excellent!It’s also very helpful that the MR button lights up as a reminder that you’re using it.Many thanks for a great little app!

- A fresh new look with Liquid Glass for iOS 26 and above.
