The only problem I have with it is there is no memory function. M MC M+ M-. Even the cheapest calculators from the 1970s had a memory. You would think it would have one in the scientific mode. That would be really useful and I would give it five stars if they fixed it. Other than that, it is a free calculator with no ads.

I have found a bug, (I don't know if it's a feature, it doesn't seem to be) example to describe the situation: type 2+2,press the equal sign, it gives 4 in green colour. When I press the equal sign again(don't do anything else just press it again) it adds 2 to the previous output (i.e. 4). I can keep pressing the equal sign again and again and it adds 2 repeatedly.
