Great app for touring and riding – Ride with GPS: Bike Navigation Review

In combination with the website, which is the best tool out there for planning or finding a route, this app is all you need for touring. Select tour route, hit ride, put it in your pocket, and the mechanical lady will tell you when to turn. If you get off route pull out your phone and look at the excellent open cycle map. If you want a on handlebar display buy a Wahoo and they will link through Bluetooth. When you're touring you can plan routes really well on an iPad mini and then they are automatically on your phone app and you can download all the maps for a route so it keeps working when you're out in the middle of nowhere and there is no signal. And at least on a plus the battery drain is minimal. Highly recommended.
