Ratings and Reviews
Needs more features to make it truly useful
It has a ways to go. Was disappointed there is no way to add notes to line items on the ‘tape.’ This is a real must, I’d like to see an ALL CLEAR button on the calc, itself, instead of having to go up to the toolbar to get to it. A floating (adjustable) decimal point that is automatically entered would speed things up when you’re doing long strings of numbers. olor schemes and a larger or better contrast display (as mentioned by others) would be most welcome. Check out Judy’s Ten-Key for Windows on how to make the perfect calculator and you will have a 5 star rating from everyone.
Will Not Open
When minimized to the dock CoCalc will not display when clicking on icon in dock. Have to right click, quit then reopen. Sometimes when opening after minimized it displays for a spit second then disappears. macOS version 10.3.2
Different key strokes for different blokes
"Calculator" means different things to different people. Some need advanced scientific or mathematical operators, some need advanced financial calculations.
I have a feeling that most people have very simple needs, and want a very simple calculator interface. This one is very handy for me to call up from the dock.
Its transparent appearance and ability to remain hovering on my screen while I make simple designs (so it’s always available) make it a very good fit for what I need. It has a few scientific symbols (more than I need), so that I can use 𝝅 to figure areas and circumferences, and it has a tape to shore up my porous brain..
I don’t know what more I could ask for, and it’s only 99¢.
