I love using it! It's so much better than my laptop calculator that I'll pull out my phone to use this app rather than my laptop's. This one lets you keep your whole calculation typed out while also giving you the updated answer based on what you inputted at that moment as opposed to some other calculators that only show you the current number on the screen. Interface is great too! Has ads, but they're small strip ads on the bottom so it's almost like having no ads at all, which is really good.

This calculator is the best I've found. It has every type of calculation I could ever need. It even has ones that I have only seenl on separate applications - many that cost to add. It has all of the usual scientific calculations,but so many more practical ones. Amazingly, this is free to use, unless you want to get rid of the adds. Then you pay a small fee. Those adds are what enable the developers of this calculator to offer it for free. Either way, this is a great calculator to handy!

It's a calculator which calculates and so much more. The GUI is clean organized and intuitive. It has tools I'll probably never need, (but will use anyway, because I can,) some tools I'll likely never need it use, yet with all those extra features the app is not the least bit crowded or force fit onto the screen. The main selling point for me was that the system keyboard would NOT randomly pop up blocking you from using the calculator as had been the issue with many other calculators I've tried.
