    Will a Bluetooth speed sensor improve iPhone 5 gps accuracy?

    The trails I ride on are very tight and twisty, often overlapping, so I've tried starting runtastic mountain bike app and put in my pack. One of the trails I ride is very short, 4.24 miles long, comparing my kong nerd 9, setup with a wheel roll out, the app knocks about a mile off of the ride. So my question is will something like the wahoo panobike sensor or something similar help with the accuracy. Thanks

    Will a Bluetooth speed sensor improve iPhone 5 gps accuracy?

    I haven't tried it with a phone app, but a sensor is good with a garmin. You probably need to investigate and find an app that will allow the speed/distance of the gps to be overridden by the sensor. This is what the garmin does; I'm sure there is an app out there that will.

    I am using a Jarv speed/cadence sensor I picked up on Amazon. Works really well with Runtastic and Cyclemeter.

    it will NOT improve the GPS accuracy.

    it will improve the accuracy of the metrics reported in the stopwatch/dashboard screen, but your track will look the same on a map.

    if you actually want to improve the GPS accuracy, you have two options:
    dump the phone and get a dedicated gps.
    buy an external bluetooth gps receiver.

    I ordered the jarv. That's what I'm looking for is accuracy in average speed and mileage. Thanks for the replies.

    So far I have done four rides with the Jarv. I have only used to the speed sensor part of it, but it works exactly as I had hoped. I've been using it with the runtastic mountain bike app. and it has worked flawlessly. Setup is as simple as it gets, no pairing, just open your app and start riding and it's working.

    Are you sure about the no pairing?

    I am using Jarv speed/cadence sensors on both bikes, and a Jarv heart rate monitor, and had to pair it with both Runtastic and Cyclemeter.

    All I know is I was looking for pairing instructions on the jarv manual, it said follow the apps instructions. Runtastic had no instructions, so I had my bike in the stand gave my back wheel a spin while the app was up and it just worked.

    Nice! Maybe that was one of their upgrades since I set mine up earlier this year.
