Backup GPS on Android

[Christopher R. Bennett]

Can anyone suggest a good app for an android phone to use as a backup GPS to my Edge 800?

What features are you looking for?

For general mapping, both aerial imagery and maps, I like the Backcountry Navigator app. You can import GPX files into it. It also works while off-line and does not consume too much battery. You can also record tracks and, I believe, export them for analysis into something like TopoFusion. I use it primarily for the topos and it works great. I use it on a DroidX and have the Pro version. Would recommend it.

For other cycling specific functions like cadance, power,etc. I'm not sure whats out there.

Navigation above all. While the Edge 800 lasts about 14 h and I carry a backup battery, it is just in case I crash, totally run out of power, etc.

I have also thought about using backcountry navigator as my backup gps for ctr.  I've got the DROID x.  BN Pro looks good but haven't explored it's capabilities yet.  Not sure how many waypoints it will accept but with my limited use of BN it seems to work well.  I wish it had better/updated topos, though.  With backup battery, it should last long enough with limited use.

Ive got he full AZT750 track with a bunch of waypoints loaded on mine. I think the number of tracks and points is only limited by the size of your sd card. The app used to have mytopo access until it was overtaken by trimble. The dev of bc was super responsive and got the usgs topos online very fast. It is a great product that i use quite a bit on bike adventures and other stuff. The ability to use maps offline is key.  I'll be using it this spring as a backup on the AZT.
