CalcKit user reviews :
Using this for years! It’s just getting better and better, with tons of useful functions and the possibility of creating custom calculation systems.
The interface was clean and intuitive. However, it’s very unsophisticated. For example, it has a function to change fractions to its lowest improper form, but you can’t use it as a fraction calculator or even allow input of a decimal number to get its equivalent as a fraction. Another example of how deficient this app is, is its interest calculator which doesn’t allow input of number of periods, so that it’s only able to calculate annual interest and not monthly or daily.
- Hello, Thanks for the review. Starting from a few months ago, the calculator displays both decimal and fraction result at the same time, so you don’t really need to use the “fraction simplifier” and “decimal to fraction” tools anymore. As for the interest calculator, I totally agree with you and it is something that will be improved in the future.
This tool does all I need and love that the functionality it did not have I was able to add through a custom function. Really good tool. I’m wholeheartedly giving 5 stars without reservations. But nothing is ever perfect. It does take a lot of clicks to move around in the functionality and some minor inconsistencies in behavior – but all very minor things. I replaced the RPN calculator I had been using for years and was happy with as this one is simply better. Thank you! (purchased upgrade to remove adds – happy to send the $)
I forgot so much basic math and calculations of %, areas, etc, of my high school and college, but I knew it was always floating somewhere in my brain. This comprehensive app found it, and allowed me to remember higher math skills from 30 years ago. So as long as the laws of physics are still around, then this is a great app for helping my granddaughter with homework or just figuring out everyday home projects. Plus, I have not even explored the multitude of subjects this toolbox offers. I just spent hours playing with its different categories. Don’t know why I posted this, but it’s well deserved.
All the lil things you need
Absolutely amazing. I’d rate this 10 stars if I could
