Decided to get a heart rate monitor for the gym and occasional run.
You strap this to your chest and it monitors and displays your heart rate on cardio exercise equipment at the gym (through Polar protocol to brands such as Technogym, True Fitness and Concept2 to name a few) or to iPhone 4S/5 via Bluetooth 4.0. Official Android app may come soon once BT 4.0 is adopted officially, but works with Runkeeper AFAIK. Also works with latest generation of iPod Nano. Item includes a Polar case for a limited time (whatever that is)
Price is $99 at Harvey Norman, ~$80 shipped from Amazon
Cheapest I could find online.
Coupon code is for a physio association but I have had my own order successfully shipped already. Coupon code is 10% store wide.
I have been looking around for one of these for AGES, great price!
… Now do I buy it before Android compatibility is confirmed or wait???
FYI - BT:LE is pretty hit and miss on Android.
Officially, the devices may have the BT4 hardware, but do not have the software to actually support it
(Some vendors and custom ROMS tried to implement their own BT stack, but nothing really worked well).
Come Android API 18 (Which should be Key Lime Pie, or Android 4.3 or Android 5) this will hopefully all be resolved with native BT:LE support in the OS.
TL;DR - Will most likely not work for Android users until mid June, when google release the new Android version, which will hopefully FINALLY enable Bluetooth 4.0 capabilities on Android devices.
