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.

If you need to figure something out, chances are that you'll find out how amongst the huge range of calculations, convertions and formulas in this app. The only thing that doesn't seem to be here is a celcius/farenheit/gas mark oven temperature converter which would be really useful in the cooking weights and measures section.

I love the custom tool feature very much and have used it to built several routine calculations. The currency converter is also very useful and it seems to be able to keep up with recent exchange rates. 👍
