Good start Decent vendor app. A few things: its a little clunky and slow to load. Some smaller coupling sizes are not available specifically in the L series
broken i was using this to check my work when selecting couplings. Now, it never makes it past rpm selection without a crash.
Cheap Junk Easily misleading, and certainly not a replacement for a professional sizing a high quality coupling.
App is now compatible with Ice Cream Sandwich and Jelly Bean.
