I thought the thinking was that chest straps didn't have the accuracy for HRV measurement?

Just checked on the HRV Elite website and I'd need a new and different HR strap. The Garmin strap isn't compatible via the iPhone.

But in principle HRV monitoring is worthwhile?

I'm no expert, but I've read it's a very good indicator of health and training load.
It's just another metric - the skill is in interpreting and responding to it.

I find it's a good indicator of the previous days beer intake...

I was on this thread a couple of years ago and believe it or not the same queries are still being put forward! Especially around HRV but also around the other elements to consider when using an HRM.
I've used an HRM on and off for twenty odd years and followed several themes/programmes which were supposed to assist in my training--I guess my underlying "wish" was that by following a principle then my running would improve. Being as objective as possible but with a hefty splash of subjectivity thrown in(!) I have to conclude after looking back over my logs that I did not improve! So I'm kind of agreeing with Nellers in wondering is an HRM worthwhile. I still use an HRM (chest strap) a couple of times a week but mainly out of interest and also to make sure I don't blow a heart gasket! I'm seventy and don't want to push the engine beyond sensibility!
I lean to thinking that using an HRM is worthwhile if you're somewhat talented and trying to shave off seconds from a PB or wanting to be ultra scientific (?) in one's approach to training otherwise it is not going to add much to what is possible by utilising a training regime which is varied and dare I say it, enjoyable.
When I was in my late twenties when I began running you'd be lucky to find a stopwatch let alone anything else but people who were not particularly talented tended to generally run faster in races than today--effort was measured by how well you could breathe, a factor which still holds good today!

Nellers, the opposite is true. Chest straps DO have the accuracy for heart rate variability readings - it's the optical heart rate monitors, or at least the wrist ones, which don't, or didn't until recently. A £20 Coospo strap from Amazon will do the job just fine.
I have to say that I think I must be one of those people for whom wrist HRMs simply don't work reliably. A while back I tested out my partner's TomTom and found it very erratic. I recently bought myself a Polar M430, which happens to have an optical HRM, although I didn't buy it for that, just as a replacement for my dying Garmin 220. And I really can't rely on the readings from that. Some of the time, particularly on warmer days when I have warmed up, it's fine, just the same as my chest strap. But often it's all over the place until I've run a mile or two. And if the weather is cold, it misreads again.
I know the standard advice is to wear it further up the arm, but I found this uncomfortable, and the watch kept slipping down towards my wrist anyway.
I'm not too bothered, as it pairs with my chest strap fine and I don't have a problem wearing that. When I'm serious about heart rate monitoring, that's what I'll use. In the meantime, the wrist monitoring is OK for when I'm out running and want to take an occasional glance at what my heart rate is.

So on general HRM training I pretty much always use the old style hard Garmin chest strap to record HR data (and guide most of my intensity during training). With some exceptions when the weather is cold or the strap is dry it's been pretty solid for me.
It's really getting to grips with the HRV stuff that I've been lagging behind. I can't see an obvious way of using the Garmin strap for it and previously everything I've seen to use a phone app needed either a different strap or an additional monitor of some sort.
The thing with the app I've now downloaded is that it does it through the phone camera. I'm not entirely sure of the accuracy of this method and wondered if anyone knew anything of it.
Anyway, I've bought it (£10 for a bit of a play seems reasonable) and I'll let you all know how it goes. I think I need a week or so of readings before it starts to give me anything resembling guidance.
Cheers folks.

What you need is an Ant+ compatible Android rather than one of those Apple things ;-P

Maybe so, Stu, but that's more outlay than a £10 app.:-p
