Love this calculator. Easy to use. Numbers large enough to see. Memory works great. Mmy old app was full of ads and was inaccurate. I tried a few others. This is the winner. I have an android device

I use this everyday to figure out what things cost per unit or to figure out the measurements between cm and inches and for other grocery shopping... 2/28/25 Still using this a lot every day and really appreciating it.

You have released the worst app update ever! Calculations involving memory—specifically multiplication, division, and subtraction—are yielding incorrect results. (Example: After calculating 2x3 and pressing M+, the result becomes 3, whereas the value stored in memory should be 6.) Basically, I found so many bugs (I can't write here because the limit) any calculation involving memory is completely messed up now! It is extremely dangerous for someone business!!! Fix this immediately!!!

Eh, it's ok but a bit hard to be sure exactly what you're doing as the + - and / sits on the far left and the sum on the far right 🤔 The calculator's design makes it difficult to trust my work and stay focused during long calculations 🤯 I might give this one a miss. Other than this though, it works well, and I don't experience any glitches, lags, faults, or issues. #Calculator #DesignFlaw #Math #LackingFocus #Problem

I go to launch the Calc App & then Google Play pops up, but I don't keep my Wi-Fi on so the error message says "You're offline" Check connection and options are Try again or notify. It seems like you can't use the App offline anymore. It used to work fine before version 1.20.0. Looking at other options now. Was easy to use, but it doesn't "add" when I need it.
