Description
Been playing Scientific calculator plus 991 for a couple months now. It’s basically a super powerful calculator app with all the features you’d need – basic math, scientific functions, graphing, and more. Pretty solid if you’re into math and need a really advanced calculator for school or work.
Here’s what you can do: there’s a basic calculator, an advanced scientific one, and even a graphing calculator. And it’s got tons of functions like percentages, roots, trig, and fractions. Took me a while to figure out some of the more complex stuff, but it’s all pretty intuitive once you get the hang of it.
Look, if you’re a student or engineer who needs a really robust calculator, you’ll probably like this. It’s not perfect – the ads can be annoying if you don’t pay – but overall it does the job. Worth checking out.

The sheer number of features is really impressive - it's got everything you could possibly need for advanced math and engineering. And the interface is pretty user-friendly too, which is key for an app like this. On the downside, the ads can get a bit intrusive, and some of the more complex functions take a bit of learning. But overall, it's a powerful calculator that gets the job done.
