Don't waste you're time
     
by NP Tom · September 22, 2017

Absolutely worst support I have ever experienced. App will not update and most calls won't function. Emailed them and no one ever responded. Don't waste your time.

Excellent until now

I have a long list of favorites. However, now, something is wrong, “bugs” the app freezes at the end of questions. It happens on all the decisions trees.

Only one calc at a time

Great resource, but app freezes if you use the app for more than one calculator. Get out of the app between each calculation.
