Jusr right

When it comes to computer programs, so many times you end up with more than you need, which means you either had to pay more than you wanted to, or have to wade through extraneous elements to use what you really want. Happily, not the case here. For a buck you get a perfectly functional (and even nice looking) desktop calculator to use for the essential functions of everyday life. Do you need scientific notation to balance a checkbook? Of course not, nor do you need all the extra buttons that go along with the arithmetic bells and whistles. This is a straightforward calculator that pops up instantly when you need it, and I doubt there's a dollar I could spend for anything that would get me more for my money.

the best I’ve found!

I have been using this calculator for a while now, well over a year & it is, by far, the best I’ve found. It never crashes, is always available (without a search through my APPs or my Preferences) which, to me, is a real plus.
I also like the fact that I can use it in 1 of 2 formats ~ either full screen or at various unlimited size adjustments, something that alot of other calculators cannot do.
So all in all, a great addition to my laptop “tools” ~ well done! :)

Does the job, but wish it could live in the bar at the top of my computer screen

I LOVE the fact that I can make it the size I want ! I just wish I could put it up in the bar at the top of my screen automatically when I start my computer, and launch it from there. Maybe that is possible now? I couldn’t figure out how to do it. Whatever you do, DON’T get the app called Calculater * Free, as it’s free for awhile, but then it wants $2, and you cannot get it off your computer as it says it is “in use” since it is in that top bar, but it won’t let you delete it. Very devious, and I will write them a bad review.

Apple: Buy this app “Full Screen Calculator” and let it live in that top bar !
