Tried out the free version, immediately got paid version. Significantly easier and simpler to use for my needs than another time calculator I've been using from a different developer.

I absolutely love this app! As a DJ I need to be able to quickly calculate song times, so I can make sure that I hit certain time marks in my show and this calculator definitely makes that quick and simple! I keep a shortcut to this app on my home screen for quick opening! Thank you to the developers for making this simple!

Honestly, such a very useful time calculator app, as I do homeschooling with my children, and have them do many worksheets based on time. Therefore, I must add and subtract a huge amount of time problems, very frequently as I check their worksheets. This time calculator has proven invaluable, so that I don't have to always do all of them.
