Saved me many hours. I used it to make custom and repeated long calculations. It uses a modular drag and drop approach. Variables are stacked top down like a list. Read on for Wish list. In my setup, I have over 100 things. Wish I didn't have to drag everything from bottom up. ( numbered lines :) Wish there was a text variable. . Wish I could save and reload work. Wish the shared text output retained the formating that looked pretty in the program. Grouped Modules that can be called?

Hi Mark, thanks for the positive review! Delighted to hear that CalcKit has been a time-saver for your calculations. Regarding your Wish list, it would be great if you could share some more details/examples via email at support@calckit.io, so we can explore the possibilities of implementing these features in future updates.

I've been relying on this app for many years now and it has never let me down. It always has what I need, when I need it, and finding it is speedy. The UI flows very nicely. The ability to create custom calculations and converters really sets this app apart. Specially useful for all the different branches of industries, research, and technical trades one may be working in. I rarely leave reviews but this app deserves it. Keep up the great work who ever y'all are.

Whoa! There are a lot of great tools here... Check out the FAQs, because the deep capabilities are somewhat hidden behind the clean simplicity. All kinds of calculators: standard stuff (volume, speed, distance, cooking, etc, ) but, also more esoteric stuff: board-feet, analytical geometry, numeric base, Roman numerals!; if it can be calculated it's probably here; and if not you can roll your own! The dev responded to my feature suggestion almost immediately, and implemented within a few hours!
