I downloaded the app with the ProPack version of CueSheet onto my Droid Razr Maxx and tried it out on a 28 mile urban ride. I had some issues with the map I had made in RWGPS but other than that it worked great. I put one ear-bud on and slipped the phone in my jersey pocket. I had turned off wi-fi and 4G LTE with the battery at 90%. 2 1/2 hours later the battery was down to 70% so about 10-12% per hour on the battery in that mode. I didn't even look at the map layout, just used the voice directions.
For my upcoming TransAm I have transcribed the ACA GPS routes into RWGPS manually. I did this because it was easier for me and mentally I have a picture of the route. Also I wanted an east-west routing and the ACA is west-east. And I don't need all the waypoints or POI. It didn't take much time to do that initially but now I have to go back through and make sure I have the queue points I want.
I think it is the best solution I have found so far.
