Cadence sensor with iPhone?
Does anyone have any experience with a bluetooth cadence sensor linked to an iPhone app? How well do they work together? I have my iPhone mounted on the stem to give me GPS stats. Weighing getting a computer too, or getting a sensor, and linking it to an app. The Computer would be more clutter if a sensor works fine, but would rather have the clutter if the sensor/app route is flaky.

Get a Garmin Edge 500 or 510. Ditch the iphone.
The new garmin magnetless cadence and speed sensor is awesome. Get those too.

I run the Wahoo speed and cadence sensor with my Iphone 5 along with the Wahoo heart rate monitor and they work awesome. I have been using both for several months and have had no issues. I have about $220 in my setup including an external battery pack that will run the phone for ten+ hours.

I have experience using Wahoo Fitness's RFLKT system paired with their Bluetooth speed and cadence sensor on a couple of bikes and have a few friends using the same setup. All of us are using Cyclemeter in our iPhones. The system works great. As a bonus, the RFLKT is small so it takes up little space on your stem or handlebar and allows you to keep your iPhone in a jersey pocket.
You should be able to use Wahoo's speed/cadence sensor without the RFLKT but I mentioned the RFLKT as it would let you move your iPhone to a pocket.

I have run the Wahoo BluSC for a couple of months, it is fairly reliable though the cadence sensor has wacked out a couple of times 42,000 rpm, I wish.
I do not like to ride with data in my face so the phone sits in my jersey while I ride, then I upload and check after.
I too have a battery pack, I have done 9 hours and still had over 50% phone power left.

Which battery packs are you guys using? I've been considering picking one up for longer rides.

I use this one. I have it in a small camera case Velcro strapped under the top tube.

I also use a Mophie Juice Pack on long rides if I think I'll need more power. But using the Wahoo RFLKT to display info during the ride allows me to turn off the iPhone's screen, which improves the battery's endurance.

I use the Topeak Panobike, works very well and never miss a beat. Also use a Wahoo HRM and RFLKT. Battery on my phone last quite awhile with this setup.

So far they seem to work with any app as I have tried Strava, Cyclemeter, Endomodo, and the Wahoo Fitness app which is the one I use. I then upload to Strava directly from the app.

Do you have both mounted on your bike? Right now I have my phone in an inexpensive Scosche case. I can see notifications on the phone but I can't keep the screen on or the phone gets too hot. I am looking at better mounts but the Rflkt seems about the same cost and should save some phone battery.

Flyin' under the radar
For those of you using RFLKT, two questions:
1. How's the connectivity (i.e. have you ever had the data recording BT connection with the iPhone drop out and lose ride data)?
2. Is it possible to get turn-by-turn navigation displayed on the RFLKT (i.e. pre-loaded courses)?

It's highly unlikely that difference in accuracy has anything to do with the method of communication - the most likely culprit is strap design or sensor placement that makes it more susceptible to misinterpreting stuff, like a flapping jersey/shirt.

Several posters in this thread have said they conceal the phone as they don't want to see the results in real time. Does that mean you don't want normal bike computer results displayed like your speed, cadence, heart rate? I don't get that. If you didn't have the iphone system and were using a normal bike computer, would you not look at the common outputs from time to time? Please explain.

I can only speak for myself, obviously, but the typical display for my garmin is HR/HR zone and cadence - IOW, in-ride, I'm only interested in my effort, not so much the results.

Wait, I get it now. I just googled RFLKT and see it is an auxiliary display that replaces the iphone for GPS and music purposes. So you can stash the phone and it still does what it needs to do while sending the display to the RFLKT. Got it.

Quote from DC Rainmaker in his summary:
The work that the Wahoo Fitness folks have done around stabilization of heart rate data is incredible and to be honest, that in and of itself is enough of a reason to buy this strap if you have a phone that supports it. It certainly beats HR strap dropouts and spikes.

I don't like having my data in route, I find myself riding to the computer which is less enjoyable for me. YMMV
I still ride hard, but ride by feel, listening to my body, breathing, heart, and especially my knees.

Yeah, I understand that. But you don't put your Garmin in your pocket. That the part about the smart phone usage I didn't understand.
Wait, I get it now. I just googled RFLKT and see it is an auxiliary display that replaces the iphone for GPS and music purposes. So you can stash the phone and it still does what it needs to do while sending the display to the RFLKT. Got it.

The RFLKT really does help to save the phone's battery by allowing the screen to be shut off.

There are some nice aspects to the phone aps though. Not sure how the Garmin works, but when I finish my ride using cyclemeter it sends a link to my email, and all my data is there to view by clicking the link.
IMHO cyclecomputers are more "solid"...they just work.....so I would probably never rely on an Iphone as my ONLY device, but I have it with me anyway and running cyclemeter with the screen off really does not use much power, I did a 4 hour ride and it used something like 10% of the battery ??
