Does exactly what it says
If you are looking for an heart rate monitor and own a 4S, look no further. This product has so far performed exactly as I wanted it to. It worked well outdoors with my phone in my pocket, worked well indoors on the treadmill, pretty much everywhere. I also use bluetooth headphones and there was no issue. Finally a product that says it is going to do something and actually does it. Price isn't bad either, doubt you will find something better for less. The washable strap is also great. Easy on and off. If you love to track your fitness, this is a great tool. …

Wahoo Fitness Blue HR is AWESOME! I use Nike+ GPS app and needed HRM to help maintain my zones. Using Wahoo Fitness app I run with both apps running. Setup Wahoo Fitness triggers at different intervals and Nike+ GPS every mile. Now I have all the info I need. Upload to Runkeeper.com for HR and Nikeplus.com for runs. Blue HR works perfectly with iPhone 4S. Only ONE device for HR monitor, GPS maps, Music playlists, and phone... AWESOME!!! …

Love this product...
I wanted to track my heart rate during workouts. I have used Polar products in the past, and was satisfied. Being able to use this with my iPhone 4s over Bluetooth, a plus.
I was worried it would drain my iPhone battery more than normal, but I couldn't tell the difference with it on or off after a 8+ hour workout. I love how light it is. It says the unit is water proof. I can't wait to try it swimming, just make sure your phone is waterproof too. I'm glad my local Apple store had it in stock. It was a choice between Apple or REI.
I don't know how battery life for the unit is, but have tested it for some 24+ hours of workouts, and still tracking strong. The battery is user replaceable. It is a CR2032 lithium battery that cost a couple of dollars. …

Blue HR can be Temperamental
(Cris) from wahoo fitness support recommends right out of box that you open the back remove the battery check the voltage it sh ould be 3 volts these are factory installed and could have sat on the shelf for awhile replace make note of date of new battery. Mine worked great for first 2-3 months then all of a sudden stop working. (Cris) Try resetting the BlueHR. To do this, remove the battery, turn the battery around (upside down) and use it to touch the positive and negative contacts together for 1-2 seconds. This drains off the capacitors and allows the sensor to reset. Make sure the battery door gasket is in place before closing the battery door.
Any other issues contact Wahoo support. …

Yes. I bought this today after looking thru the compatibility on the manufacturer's website. I hav e been using Runtastic Pro for three months and every week I use this App to track my running habit. This Blue HR strap works well. Keep in mind that switching on the Bluetooth on your iPhone might not discover its presence. It is not until you wear it on and batch your App will you find the reading showing around the red heart icon. Enjoy! …
