Calculator Pro Does Not Work

Just installed and it shows in the menu bar - shows it open but won’t open. Can’t close it either — so its stuck. Tried restarting my computer and everything. Can’t do a thing with it. Please refund my $2.99

Very very handy calculator app!!!

I have just had this app for a short while now, but I know for a fact that it will come in very handy for me in the future. It is 100 times better than the Mac calculator hands down! I love the hot key functions such as hide, global hide, clear, copy, delete, “x” for multiply and either the comma or period for a decimal point. Very ingenious! There are a few things that I would love to see in a future update though. The first thing, would be an option to turn the “+=“ key into only the “+” key with one keystroke because I accidentaly clicked that key a few times wanting the plus function but it evaluated it anyway. Another option that you could add would be to use both the slashes (the backslash and forward-slash) as divide functions. And possibly, if you could make it where the paste function could be pasted into any part of the calculation and not only in the beginning, that would be amazing!! Lastly, I would also love to be able to use parentheses in my calculations. But other than those few ideas, it is an amazing and very convenient app. Extremely well made and very user friendly!!

AWESOME app. Responsive developer too.

This calculator is fantastic. I’m the CEO of a small business and am constantly using spreadsheets and doing quick calculations. Having this in the menu bar allows me to run quick calcs at a moments' notice. The tape functionality is beautiful, it allows you to have up to six decimal points, and it starts up right with my computer. This is a much better overall experience than that apple calculator. Thank you!
