I've been looking at this recently.
All I want is to continuously monitor HR via something worn on the wrist. I also wanted to be able to set an alert if my heart rate goes above / below certain values that I select. I do NOT want the blooming thing to try to bully me into upping my steps etc...
1. Mio Alpha 2:
On paper looks good. It is waterproof so you can shower with it. You can set up heart rate alerts. Has good recommendations from fellow PR members who have been monitoring like this for a while. Cost = £109 (early 2017). It is quite chunky for those with small wrists.
I had a nightmare trying to sync it with my phone. I triple checked that my phone was compatible. I was a techie and on a good day can usually still figure stuff out. Couldn't get it to work and it got "stuck" in a pattern of flashing lights. So I got my husband, the Gadget King (man of many superpowers!) to try it using his, newer phone. No joy. Several goes with customer support (in Canada) no joy and when they realized they couldn't help me they just abruptly disconnected the call (I had remained perfectly reasonable and polite throughout). I checked online forums and lots of others have had similar problems.
Hated the charging connector for the alpha 2 - a tiny, short cable and it was very easy to knock the alpha aside and off the charging connector.
Sadly, I returned the Mio Alpha 2.
2. Fitbit range:
I was considering the new Alta HR. I was fed up[ trawling through all the sporty blurb so I just got in touch with their customer support to ask if I could set it up so that the device itself can alert me if I go over or under set heart rate thresholds. The answer is no, you can't - you can look at it after the event on you phone.
3.
Garmin Vivosmart HR:
I saw
@TiredSam 's post on the Garmin and had a look at that. Loads of functions and it looked a bit chunky for me so I had a look at the Vivosmart HR instead. Smaller with less functionality. Note: HR+ is the GPS model and as I'm usually housebound I don't really need that
.
It does send data to your phone but apparently you can also set it up to share data to a computer if you don't have / want to use a smartphone. I haven't tried that.
The device will continuously track your heart rate BUT will only actually alert you when you put it in an activity mode - then it vibrates when you go over or under your set thresholds - you can also sync this with your app to read later. In continuous HR tracking mode you can get a summary of your HR lows and highs over the last 4 hours from the device itself if you want.
If I know I'm going to do something such as put a laundry load in, empty the dishwasher or meditate I can just stick it in an activity mode and it will use my preset alert thresholds. You can edit the title of these activities and make basic notes when you sync up with your phone later. If I've understood correctly the device will store up to 7 activities in one 24 hour period and will then start overwriting the oldest ones.
Apparently it is waterproof but I have yet to work up the nerve to take it into the shower with me.
It is chunky but I do have rather scrawny wrists, but doesn't seem as intrusive on the wrist to me as the mio alpha. It is quite comfortable and I haven't managed to catch it on any door handles (yet).
It does do lots of clever stuff in conjunction with a smartphone that I don't need such as weather updates and call, text and email alerts. I just switched them off.
It does have functions to remind you to move etc. but you can switch all those off. If you set your goals for daily number of steps higher than you are likely to actually achieve you don't get any alerts about those.
It is charged via a usb cable and connector. The end that connects to the vivosmart HR is a bit fiddly but clicks in quite firmly. It seems to charge within a couple of hours. You can check you charge level on the device in continuous HR mode and while it's charging. You can stop it continuously monitoring HR if you are conserving battery for some reason.
It cost just under £90 incl. postage (early 2017).
I think I'll keep this one.
