Idapt Ramp & Step Calculator for Android
Cannot enter data as headers and footer (advertising) are in the way and the data window will not scroll to alow you to get to the data fields. It may work better on a tablet not on my phone
I've used this for several years on site with clients. It is simple to use & allows all options to be accurately explored. I have it on all my devices, iPad, iPhone & Nexus 9.
Does not allow just two parameters to be input, will not allow selection of calculate unless all fields are populated

Terrible. Can't scroll, costs money and still has annoying adds. Would have rather spent that 2 bucks on 4 maccas ice creams and dropped them
