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.

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.

My Go To Calculator!

I love the convienance and simplicity of this calculator. It's located in the menu bar for easy access and can be unattached if you need to move it while on a website. I've purchased other calculator apps in the past and this is by far the best one for me. I would not hersitate to buy this calculator app again! I don't allways write reviews but when an app comes along that I really like, I like to share my opinion with others. I value the opinion of other people also while shopping for specific apps that I am interested in.
