Scientific Calculator fx-991 reviews
4.7 out of 5, based on 7,246 reviews.
What people like
- Very easy to use
- Great for school work
- Free alternative to physical device
What they complain about
- App crashes immediately on launch
- Math errors in big numbers
- Fraction conversion feature is broken
- Ads are intrusive and annoying
Best one so far
This has been very helpful for my Electro Technology classes. I don’t own a physical one and this is so useful plus free. There are ads but it’s not that bad they are not in your face. For the most part you can ignore them and they don’t throw it in your face forcing you to pay for it.

Reseña de Marcus
Es la aplicación más curada y útil me llamo marcushh el ora aya tata
Annoying problem
The latest update is neither good nor convenient at all, especially when performing a calculation and displaying the result immediately; it overrides the calculation. The older version is much better. I hope the developer fixes this problem because it's annoying.

Doesn’t work
I was trying to use it for my school homework and when I try to open the app, it closes it as soon as I open the app, it’s annoying, I guess it’s only me but idk
Muy buena
La app es excelente
Small issue
It alright, its very useful although i have one problem which is the s<>d It seems not to be working all of the sudden, it used to work well but now its not I cant able to know the answer in fraction but the decimals only (for example 60/360 and the answer gives me 0.1666 but i cant change it in to fraction since the s<> isnt working) Is there any way to fix this problem?
Love the Calc
I have had a great time using this calculator for school and it has helped me in so many ways
