I’m only able to find apps that are compatible with a bluetooth strap. But I don’t want to buy one if I don’t need to.
I’m not sure ANT+ protocol even supports HRV, at least I don’t think it did last time I checked. I know some of the combo Ant+/BTSmart straps only support HRV over bluetooth. I just got a Wahoo Tickr, works well with my Garmin and with my HRV app and tablet-based trainer software.

ANT+ actually requires the HRV data be populated per the spec. Bluetooth Smart technically doesn’t require HRV data be transmitted (many do though these days). This has had the interesting side effect that for optical HR sensors, companies a few years ago starting putting in what was basically junk data. Else, they couldn’t get ANT+ certification. ANT+ didn’t specify it had to be accurate, but rather, just had to be something.
As far as apps (assume you mean phone), it’s a bit more obscure to find an ANT+ app that logs HRV data. I’d poke and see if IpBike does, as that might do the trick (Android). Once you have it recorded on your Garmin though (most Garmin wearables will record the HRV channel), you can use apps like Sport Tracks to look at the data (details in one of their blog posts here: https://sporttracks.mobi/blog/how-train-hrv)
Ironically, HRV data is still rather variable between straps. I did an experiment last winter on a trainer one day where I logged a bunch of different straps worn at once, specifically focused on HRV data. Totally different results, despite having matching baseline HR data. Can’t figure out where the heck I put that data, so maybe I’ll do it again. Either way, my trust in HRV-driven data platforms (which are all the rage right now) is pretty low.
elite hrv for one, there are others, they weren’t particularly hard to find.
I recently downloaded the HRV4training app and have been very pleased with it so far - no straps needed.

I guess we should clarify the possible uses.
If you are looking to get HRV data during workouts, Ray is right in that I think the only option to record to HRV during workouts on a phone with ant+ is ipbike.
If, on the other hand you are looking for an app to take resting hrv readings in the morning, then I will agree that the camera-based options are the best and the best among those is hrv4training - which is apple only. The reason for the camera-based is that it is just simpler to grab the phone and take the measurement.
There are a couple of android based camera hrv apps, but for my own camera, they either didn’t work or the lamp was too hot to use. But as i said earlier, there are at least a couple of ant+ android hrv apps.
I’ve been using Elite HRV for the past few days to try it out. It seems to work just using my standard Garmin ANT+ strap and an ANT+ dongle plugged into a usb-otg cable (android phone).
I have no way of knowing how accurate it is, but it has been consistent. It is a kind of a pain to roll over in the early morning and put a HR strap on in bed, then plug in the cable and start up the app for 2 1/2 minutes before getting up. Not sure how long/often I’ll keep up this routine in the offseason, since overtraining is probably not really a concern right now. Maybe a good time to collect baseline data, though.

I tried elite HRV last summer, it worked with my garmin hard strap.
