Model Scale Calculator for Smartphone (Android)

[WaltP]

For android, here's an app I developed for model RR. Calculates
-- grade
-- scale speed
-- helix
-- scale measurements
-- ohm's
-- scaling drawings
-- easement calculations
-- english/metric conversions

If you play around with it, let me know if there are any problems and how you like it.

I also have a computer version with a lot more functionality, if interested.
