Comments on Scientific Calculator Plus for Android
★★★★★Randall Richards· Jul 15, 2026
Near perfect RPN calculator, worth every penny. Would love it if the precision "P:#" setting (shift "ENG") controlled number of decimal places. Using P:3 in ENG mode with 250E3 shows 250.0E3 and 2E3 shows 2.000E3; it'd be nice if using P:3 showed 250.000E3 and 2.000E3 like some older, physical, real-world scientific calculators do (like Sharp EL-512H and kinda like HP-42S).

Best calc app on the market. I just have 1 issue. I use nonplus version with retro theme on my galaxy a21s and the numbers on the calculation screen is black, but I purchased plus version on my xiaomi mi 9T with retro theme and the numbers on the calculation screen is white and hard to read.
★★★★★Chin Huat Tan· Dec 27, 2025
This is the best calculator with full RPN and algebraic mode. The app also has beautiful themes to select from.

It will not let you have a cursor to adjust your equation, so you will have to rewrite the whole line which is unfortunate as this is something included in most calculator apps. I have asked about this and have been ignored.

Doesn't get the right results the results are mostly off by few numbers

Display keeps blanking every time I switch to another app! It's getting to the point where this calculator is unusable!
★★☆☆☆Greg Wagner· Sep 5, 2023
Used this app for years. Probably close to a decade. Even through being a physics major in college. Absolutely loved it. New update is terrible. Switched to a weird font trying to be aesthetic instead of a normal, highly legible font. And the new button layout/sizing is a downgrade-not as functional. Not sure why any changes were made. With that being said. Will continue to see if it grows on me- I owe it to this old friend. But really wish I could revert to previous version...
