Description

Been using Calculator for a couple months now. It’s basically a really advanced scientific calculator that can do all sorts of complex math – trigonometry, logs, exponents, and more. Pretty solid app if you’re into that kind of thing.

Here’s what you can do: there’s the standard calculator functions, but you can also graph equations, convert units, and even review your full calculation history. It’s got a ton of features packed in. Took me a while to figure some of them out, but once you get the hang of it, it’s super useful.

Look, if you’re into math and need a powerful calculator, you’ll probably like this. It’s not perfect – the UI can be a bit cluttered at times – but overall it does the job really well. Worth checking out for sure.

Editor Opinion

So here's my honest take on Calculator. I've tried a bunch of calculator apps and this one's probably the most full-featured I've seen. And the scientific functions are great for advanced math, and being able to save your history is a really handy feature. The only downside is the UI can feel a bit overwhelming at first, but once you get used to it, it's not too bad. If you need a powerful, do-it-all calculator, I'd say this is one of the better options out there.

Wouldn't recommend. Reason? Ads. Ads when you open the app. Ads if you want to calculate. Ads if you want to see a graph. This was the pinnacle of Android...
