Great Product

This is a ‘go to’ product that is simple, appealing in appearance and basic enough without all the unnecessary buttons and gadgets that aren’t needed. I have this loaded on multiple devices (at minimum-5 devices) and will continue to use it for years to come. My only draw back is my own. I’m cheap so, I am annoyed by the advertising but, I find it is worth the cost, just don’t want to pay for it over and over for each device I own. It would be great if you could pay one fee and somehow it recognizes you as the owner on each of your own devices but, that’s the business. No worries for this software, safe, affordable platform.

It has a back space button!

This is a lot better than the standard app that came with the iPhone. This app has a good response when pressing the numbers and calculations buttons. I mostly use it when I want to calculate my spending and banking but most of all I like that it has a back space delete button for the mistakes I make during input. I would get so upset with the standard app that came with the phone every time I made a mistake and had to delete the entire entry and start all over. This is a good little calculator; responsive, easy to use, read and it had a back space delete button!

This app is just what I was looking for. I like being able use backspace to change a number that I entered wrong. I also like taping on my answer and looking at the history to verify my entries. If I had a number wrong, I can tap on it and change it and continue on from that point. I can clear history at any point or I can keep it running until I’m thru. Or, I can come back at any point later and look at it again until I have cleared the history. This is great, and I don’t know if I have experienced all that this App has to offer. I have been impressed! Thank you developers!
