Good but if you go to a different option you can't get back because of the advert at the top
Bismag calculator Good graphing calculator. However to use it to calculate combinations or permutations the keyboard use is too messy. You need to work to offer a much better sution. See mathlab calculator for the same facility.
Malware This app somehow hacked the uninstall mechanism, displaying a pop-up whenever i try to uninstall it and preventing itself from being removed. I don't care how good of a calculator it is (and it isn't that good), that is the behavior of a virus, not a legitimate app. I hate to think what else it has been doing to my phone.
Best graphs I see no app better than this one in drawing graphs
The best free calc at the moment I like the interface. It is pleasant to have all the calculations written in string and even keep some of them accessible in the log.
