I too contemplated using a smartphone as a bike computer and eventually bought a Garmin Edge 800, which I've been very happy with. Here are the advantages it has: GPS is better. Compare these two GPS traces from a ride my friend and I did yesterday evening (taken from Strava). This is a 2.5km climb, part wooded and part exposed. The first is my Edge 800 ...

I do think that an iPhone and ANT+ makes for a pretty compelling combination. One thing that the dedicated bike GPS hardware has all over a smartphone is battery life. While you can get better battery life out of a smartphone when logging a ride than most people imagine, it's still not close to the battery life you can get out of dedicated GPS hardware. You ...

As a plus for Smart-Phone apps, they are likely to progress quicker, add features faster, fix bugs faster, and provide more frequent version updates than GPS units. Another plus for smart-phones is that I'll take my cell phone on a long road ride anyway in case of emergency. Carrying 1 device is easier than 2. A plus for a GPS unit is that it is probably ...

The wheel sensor add on will do quite a bit to improve the accuracy of the GPS based current speed. The distance will generally be accurate, to within error values of 50 meters, or so depending on hardware. Most phones, especially with android, are on the lower spec of GPS design, using wifi databases and cellular triangulation to augment the GPS positioning ...

It would really suck to be 30 miles from home with a dead battery. Cycling computers can often run 10+ hours with a GPS. Some smartphone/app combos have questionable ...

DriKase and Drikase XL (for large phones or phones with cases) are good waterproof phone cases which mount to your stem and keep your phone dry while being able to operate it through the liner. It doesn't set it out front of your bars though. http://shop.alt-gear.com/c/bikase

Having used an iPhone app for over 3 months now, I can definitely say that it has been very helpful. Just make sure the phone is fully charged before the ride so that there's enough charge left, in case you need to use the phone on your way back home. Some more pointers on who might find a phone app useful Someone who is primarily interested in shorter ...

I would probably choose a "best of both worlds" option: Get a simple bike computer to monitor speed/distance/time while riding and have a smartphone with some app running in a waterproof pocket on me to have a GPS track to look at for after the ride (and when I'm lost). Bike computers are much better than a smartphone for during rides: More accurate ...
