All in One Calculator

This is an excellent Free Calculator, also free of Ads.

I have been searching for a programming calculator for a while and have gone through quite a few apps before finding this one. It does everything I have been looking for that other apps lack. Being able to look back on calculator history as well as comment on operations is a feature I didn’t know I needed, but has come in use multiple times. The unit conversion has more units than I have seen in any other app and shows all units converted rather than having to pick a 1:1, which is very handy for quick comparisons. The developers are also very helpful and quick to respond.

I'd give this at least 4 stats if it wasn't for all the nagging about logging in to my iPhone account. Every time I start up the app it nags. I have no intention of ever logging in to satisfy this app as the os no legit reason to needed such a thing for a calculator.

Super calculator full of nice features!

It combines all the different calculators which makes it really useful.

Wow! This is a really nice app. Lots a of features that are available when needed and are out of the way when they aren’t needed. Navigation via sidebar is super cool!

Just try to calculate 68.4 / 15... This can be a source of many problems... And yes I used the dividing operator not the slash...

On my iPad Pro this app ‘blinks’ every time I enter a number and two taps of the enter key are required to put a number in the stack. Most of the time the keypad is unresponsive to entering numbers (as opposed to the immediate and positive keystrokes with which I am typing this review). Lastly, trying to enter an exponent, such as 10 E-6 using the y^x function yields 0.

I tap the answer area and it gives a “copied from Google” message, but the number stays “0”. If it’s more complicated than that, I can’t find documentation that says so. Edit: Thanks Ramon. Double-tap works great.

This calculator truly is a one stop shop for all my calculating needs. Though it offers so many complex functions, the interface is user friendly and easy to work with. I especially love that I can record my answers for later use. 2020 was a crappy year so it’s great to have a straight forward high functioning reliable calculator.
