Rapid & Quick Calculator Pro

It has the best history of any calculator I've tried. I have had it for a few years now & still love it!

So far so good. Let’s me calculate billions.

This app is honestly the best “simple” calculator app I’ve come across. It’s not a scientific or graphing calculator; it just has the basics for the most part, but the amount of things you can do is outstanding. Want to copy the answer you just got to paste it elsewhere? No problem. And what you can copy is not just limited to an answer. You can even edit past expressions! I love that you can also pick an answer from any previous equation and use it in the one you’re currently working on. That’s been super helpful, not being limited to only using the previous answer. I also really like the tax button. There are four options for tax percentages you can customize, and I use two for tax percentages and two for tip percentages. It’s really handy. I also really appreciate being able to just add on to the list of equations I’ve done in the past, but also be able to delete individual lines as well as the whole thing to clear the log, so to speak. I have the option turned on that alerts me before clearing everything after I hit the clear all button, which is nice to have as a kind of backup to make sure I really wanted to do that and didn’t hit the button on mistake (it’s caught that mistake for me a good few times!). Lastly, it’s also really neat that the colors and font are customizable. I really dig that. Plus there are a few more options in settings for rounding, decimal marks, etc. I don’t write reviews very often, but I really felt compelled to write one for this app, which I’ve been using as my sole calculator app on my phone for a good while, because I really do think it’s that good. Simple and easy to work with and also very customizable with many ways to make the simplicity more powerful through giving the user the ability to copy, edit, share, and more. 10/10 recommend!

Muy bueno

This is the calculator every phone should come preinstalled with.

After I clear the calculator and close the app when I re open the app random calculations are in my current calculation box. Why does this keep happening????

Best I’ve used. Love the tape feature

This works great for large sets of numbers. It allows you to see and edit the numbers that you have input.

Especially great on an iPad. Sure, it does all the math stuff. However, the tally tape is great for project work and research and the ability to export to other apps makes a goto app when it comes time to crunch numbers.

Intuitive, easy, accessible.
