After changing phone, I can't connect polar flow at all to the OH1 (it just hangs). Have to use PC to sync now
I rescinded 2.5 stars as it was the vendors decision to use one of the most unreliable wireless protocols that exist (bluetooth), and thus the blame is squarely on their shoulders when it doesn't work
Heartrate seems accurate, but i am no authority. i love how well it works now and am fascinated with the cardiograms, especially during sleep.
Set-up was a pain because it wasnt 100% clear what this Polar ecosystem is to a beginner, and the masochistic frustration that is bluetooth connectivity
Here are my top tips after an initial struggle in case anyone else is in my boat:
Turn off bluetooth on your phone
Get Polar Flow android app, create an account
Stick OH1 in PC to update by downloading the polar Windows app
Get Polar Beat app (not as necessary)
Attach oh1 on arm, press button once.. wait till flashes green every 1 sec (found hr)
Press oh1 button twice, green light now flashing in fast green doubles (if hr is locked on)
Leave oh1 20 min to get data, do the dishes
Now turn OFF oh1 (long press)
On your phone, turn on bluetooth and for some reason I had to turn on GPS as well for this to work
Turn on oh1
It should be detected automatically as it broadcasts a datastream
If it doesn't try "devices" and see if its there
Oh1 will flash blue as it downloads data to the Polar Flow app
So what wasnt obvious to me is that you can let the oh1 do its thing (record a sesh) then turn it OFF to end sesh then on again to download data to POLAR FLOW, whereby you can analyse the cardiogram at your leisure
POLAR BEAT does not use downloaded data, but manages the live broadcast.. so you can take a peek at your Hr, or start recording a sesh using bluetooth capture of live data... If youre like me and hate bluetooth youll know this is a wild, drug-induced fantasy..
So to recap turning oh1 on, it will try and find your hr then sit there broadcasting to anyone interested, while two presses will start using internal memory.. with no need for external hardware
As mentioned, far superior to wrist based HR, but still not as good as chest based HR measurements.
I also have the newer version (June 2018) of the OH1 and the (Feb 2017) H10 chest strap which was the one that got me hooked on measuring my heart rate during every workout.
So three heart rate monitors:
Feb 2017 version of the H10 chest strap
Sept 2017 version of the OH1 armband
June 2018 version of the OH1 armband
I decided to try the armband version after two minor annoyances with the chest strap version (when doing pull-ups and bench pressing).
Having decided to buy the OH1 armband version, I bought the newer June 2018 version of the OH1 purely based on the Amazon website telling me that there was a newer version, and before doing any research on the improvements over the Sept 2017 version. After buying it I looked for relevant info but couldn't find any. Indeed, even as of today, there's no indication at all on the Polar website (or anywhere else) that the OH1 has been updated. It's only Amazon that says there's a newer version when you visit the page for the Sept 2017 version.
I then bought this older Sept 2017 version to check that there are indeed differences... the boxes they come in are different and they have different product numbers so I guess they must be different even though both are called OH1.
There's also no difference that I can notice in their functionality. And they seem equally as accurate and consistent as each other and the H10.
So if I had to do it again, I'd save the difference (about twenty pounds when I bought) and buy this Sept 2017 version rather than the June 2018 version. Or, better yet, if you can, wait for confirmation of the improvements in order to make an informed decision. Otherwise the premium for the newer version is simply a reflection of faith in Amazon and Polar !
All the observations below apply to both versions of the OH1 (and most also apply to the H10). I can't stress enough how useful the Polar Beats app and the Polar Flow website are for tracking and analysing my workouts which in turn motivates me to do more workouts.
My main observations:
1) Pairs with the Polar Beat app on my iPhone every time
2) The Polar Beat app does what I need for recording workouts and workout data; treadmill, elliptical, barbell, between 30mins and 120mins
3) Second-by-second heart rate monitoring and data recording
4) The Polar Beat app records how long the workout lasted and estimates calories burned based on second-by-second heart rate measurement
5) Download to spreadsheet all recorded data as csv files for bespoke analysis
6) The Polar Beat app automatically uploads data to the Polar Flow website calendar for tracking workouts -> oddly, seeing my workouts in a monthly calendar format makes me want to train regularly and avoid empty days
7) Armband is adjustable for length and comfortable enough to pull on and off my arm
8) You choose in advance whether to wear the armband around your bicep or your forearm, and you have to let the app know (I wear it on my forearm with no issues; it does leave a temporary impression on my skin, where the band strap and the heart rate monitor press lightly into the arm)
9) The USB-charging cradle is easy to use
10) You can get the heart rate monitor to record a workout away from the paired phone, but you have to instruct it to do this using the paired phone first
finally a proper alternative to a chest strap , works great with garmin forerunner 935
Doesn't always connect easily to phone/ipad for download or monitoring.
Tried to contact support via Amazon, URL error to contact the vendor.
An absolute joke, stay away from this product because it is just a matter of time it will stop working.
