Comments on Scientific Calculator for Android

★★★★★ Shafayat · Feb 25, 2022
Love this app. Long time user. Noticed a tiny issue, if you set ANS to 0 and do ANS/ANS, you get 1. Also, would make a big difference if the minimum haptic feedback was shorter, say 5ms. Currently even setting it to 1 seems delayed and long.
★★★★☆ Andrew Bohlken · Nov 16, 2023
Very good calculator as far as I can tell (I'm no expert). More instruction on how to use various functions would be invaluable, as would a help/search function. Eg can I edit the axis and add points on a line in a graph - where do I find out? Can I change axis between log and linear or semi log etc.?
★★★★★ Timothy Gbadegesin · Sep 17, 2024
This is the best scientific calculator, I've ever used on Android. Everything works smoothly.
★★☆☆☆ Toma Hawk · Dec 14, 2023
Thanks for reply. After a calculation, the outcome stores in ANS. I will then retrieve ANS and add a minus before it, that is -ANS ; then I use the figure that is made negative for countercheck my calculations in order to ensure that I did not make any entry errors. I also use the same figure stored in another memory. And the final sum should be zero meaning that there is no human operator errors incurred in the calculation process. Hence, the +/- button is very important to me. To place a - sign
