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, so we can explore the possibilities of implementing these features in future updates.

I Really don't like that it does NOT rotate on my LG Android phone to landscape. Also, why couldn't you include a proper history that's truly a functioning long term history. One that can be managed, that way delete everything IS NOT the only option. It's far more efficient to retrieve equations/formula's and results from history then trying to recollect, rebuild and re-calculate from scratch. AND, When assessing what-if scenario's, retrieval of historical work & data saves time and money!

I'm a person who has to download and try all recent apps and narrow down to a favorite and this calc app is best I've found so far. This is namely for people who like customization and a lot of available features. It is the most convenient and quick-to-access unit converter and calculator. Enough options to satisfy most anyone. Every feature has an available shortcut which makes it integrate or enables utilization by many other apps such as Tasker. Great job and thanks for the customization.
