Version 2.9
Review by Urbanwayfarer69

Calculator - I find this calculator very handy and use it several times a day. It can be detached from the menu bar so it can be moved where its needed and not in the way of things.

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.

Review by Ashley Citibnker

CPU HOG - As a previous reviewer mentioned. I was experiencing on my MacBook the fan running loudly and when I checked what was running in the background as per CPU percentages Calculator Pro was extremely high Over 651% usage. I was alarmed due to the fact that this is supposed to be only a calculator app. Once I quit the application my CPU percentage came down and my fan stop running. I liked the application but I wont risk frying my CPU from over heating I will be deleting app. ** I emailed the developer and he responded quickly he said he will look into the CPU usage I will update my review once the CPU usage is resolved. Thank you for the quick response .

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.

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.
