Version 3.6.0
Review by Springly78

Calculator Always Ready - My on board calculator that came with my MacBook died and no longer looks like a calculator, acts like a calculator nor quacks like a calculator. I was looking for something that I could use while shopping. Found this calculator and it is perfect for what I need. One of the best parts is that I don’t have to shut all the windows to get to it. It stays on the toolbar next to the bluetooth sign so, in that respect it is better than what I had .The numbers are large enough for me to use without my glasses, it has a clean appearance and it was FREE. I might also want to add that this the second calculator that I have gotten from the App. store. The other was kept getting lost. This is a review for the basic version.

Version 3.1
Review by dtperk

The clock is ticking for the developer... - Boy, I was a sucker for this update. Owned the app before for free, with no ads. I trustingly paid $2.99 to get this update, with the promise of it being an improvement. As other reviewers have pointed out, the new and improved version has an ad pop-up that’s constantly sitting over the last two rows of the calculator keypad, so you can hardly see those keys. Have yet to get a response to the email I sent the developer. Now is the time when we’ll find out if this developer is honest… or is a con-artist.

Version 3.6.0
Review by richefille

Doesn't work AT ALL - I used to love this program. It was the best calculator out there. But now it has gone rogue and this once wonderful program has been orphaned by the developer!!!!! The program is no longer functional. The icon is visible as if it's open, but when I click it, nothing happens. When I try to delete it so I can download again, it says it cannot be deleted because the program is open. I have tried restarting my computer but the program still will not open, and doesn't show up in the list of open applications, even though it shows that it's open in the Activity Monitor. It takes up more CPU time than any other process, heavily impacting the performance of my MAC, slowing everything to a crawl. I sent an email to the developer for support but it was ignored. Don't waste your money.

Review by viaTech

Clean. Unobtrusive. Stable. - Calculator Pro has everything I want in an accessory app — always there and ready to spring into action with a single click in the Menu Bar. It is a beautifully crafted app with the full functional feature set of a standard calculator, and I don’t know of any other full-featured calculator with its minimalist footprint. One reviewer cites an issue with possible excessive CPU utilization which I have not personally experienced and, therefore, cannot speak to. I can say, however, that in all the months I’ve been using Calculator Pro in Auto Start mode, I think I would’ve noticed it at least once but never have.

Review by justjoan123

Great, when it’s up... - This calculator has just about everything I could want, were it not for its nasty habit of losing its memory in between sessions. One of my most common uses is to keep track of my checkbook transactions. That means that every three to five days I willl call up my bank statement and then use the calculator to enter my checking account activity. Perhaps every four times or so the running total has blanked out and I am back to zero. If this could be fixed I would give the app a definite 5-star rating, but so far it’s 4.

Review by MarcosGood

Excellent clean arithmetic calculator with a tape. - My needs are relatively simple. Just basic arithmetic with a tape. That’s what you get here along with an extremely clean minimalist design. Works great. The only thing that it’s missing that I would like is a memory function.

Review by Mpoin01

A must have!! - I do a lot of calculations on my desktop and this tool is a “must have” app on all my computers. The tape is great when I have long lists to add.
