I hate the calculator in iphone so I downloaded this app and love it ever since. This app is way better - the interface is user friendly, and I love the history feature!The only thing that I would love to change is to have the brackets () button on the primary panel, instead of wiping to the other one and come back. Ideally, 1 button on each panel.
Good, but where is antilog?
Chemist13
I don’t mind the ads at the bottom (they don’t get in the way like other calculators). I can live with the 2nd key changing ‘log2’ to ‘ln’ and ‘e^x’ to ‘2^x’ instead of (what I think is) the more sensible ‘ln’ to ‘e^x’ and ‘log2’ to ‘2^x’, or even ‘ln’ to ‘log2’ and ‘e^x’ to ‘2^x’. I may be missing something, but where is the antilog (or ‘10^x’) button (I would expect it to appear in the log10 position when ‘2nd’ key is selected? At the moment I need to store the value in memory, punch in 10, x^y, RM, to get the antilog (there are other ways, none as simple as a ‘10^x’ key). While I’m at it, the log10, ln, log2 of 0 should produce an error, not a ‘0’ (similar to 1/x of 0). Otherwise I’m happy with it :-}

Good calculator but ads now too intrusive
Squid009
I have used this calculator for some time. I like the layout, it is clear and concise. Like many, I use the free version as I simply don’t use it enough to warrant a paid version. Consequently I am happy to put up with ads as this is the price one pays for a free app. Thanks the deal, right!! Generally not a problem. However the advertisements now appear to have become more intrusive and sort of jump out when doing calculations.The outcome is that I will stop using this app. A pity really as everyone is a loser. I don’t see the discreet ads so the advertisers miss out. I don’t get to use a good app so I miss out.

IWatch
WookaY
I cannot get the EQUAL sign to work on my iWatch so unable to calculate anything, even on the Adv. free version I paid for. You really have to hard press any of the numbers to get them to work. Disappointing. I deleted the App as I have a number of calculators on my iPhone but thought one on my iWatch would be good. I have since found another calculator App that works wonderfully on my iWatch. Perhaps the Developers for the above App could work on getting it suitable for the iWatch. That would be great. Thank you.
In this latest update you'll find:
- A fresh new look with Liquid Glass for iOS 26 and above.
- Bug fixes and performance improvements.
Thanks for your support, and enjoy using our app!
