Best calc app you're going to find – EduCalc Classic Pro Review

No seriously, this was one of the first apps I ever downloaded and the maintainer(s) have been excellent since day one. That was about...ten years ago? Something like that. Not many have that kind of track record and this app does pretty much everything a TI-84 does (except BASIC scripts).
