Rapid & Quick Calculator

I’m old enough to have used adding machines with tapes back in the days. Essentially that is what I was looking for but with couple other options like highlighting the line and incorporating it to the current equation. This is the only calculator that did exactly what I was looking for. It is simple and very intuitive app. I use it all the time. I never use other calculator app unless I need a scientific calculator. I really don’t know how people live without it.

Updated review: Out of curiosity I’ve tried a few other calculator apps. They lasted less than 5 minutes. This is my go to calculator unless I have to do advanced mathematical calculations. I rated this app 5 stars in my first review, and it’s still gets 5 stars. Update to my review below. The more I use this calculator app the more useful I find it. Previous review: This is a basic calculator, with a few extras. The history, being able to use the history results, and being able to send the history to ones email is most handy. I've not had this app long, but it has become my go to calculator, except on the rare occasion when I need to use a scientific calculator. The simplicity of this app is what makes it so handy for 90% of what I need a calculator for, coupled with the history it is one of my most used apps.

Great calculator, way better than the standard iPhone calculator. I like how you can scroll up to see previous calculations, and how you can click to select previous answers to put into a new computation without having to type them. I do wish it had a date reference somewhere so I could look up something I added up last Tuesday, for example. I run into this issue a lot.
