Convenient way to take HRV. I bought this because I didn't fancy mucking around with chest straps every morning to take my HRV. I can get a consistent good-optimal reading in a dark room with my finger over the camera and flash (on my phone they don't line up with the axis of the phone so I turn the phone almost to landscape to cover both). I've dropped my review to 3 stars 'cause its been 6 months since I complained that the dates aren't right in the dropbox export and nothing has been done.

This app offers an extremely low-friction way to gather your daily HRV readings, as you don't have to use an external device, just the camera on your phone. The data seems to track fairly well with other methods of gathering HRV I'm using. That, coupled along with the extensive write-ups on their blog has me convinced the data is accurate. My favorite thing though, is the way it correlates data gathered from your daily questionnaire and other health and fitness services to give you a comprehensive overview of how your training affects your general level of stress. Note: These correlations are not available right away, be sure to give it some time to build up sufficient data to unlock the extra insights before you decide it's not worth it. Given that the app is affordable and doesn't require (but can use) an external sensor, it is an excellent value. You can pay much more and get less in other places.

Bought this years ago and keeping checking in every other years to see if this app works - but nope. Taking readings using a camera phone is sub-optimal. Tested this on 7 devices from various manufacturers on both Android and iOS. I followed the documentation to the T, and judging by similar compaints from other users, it is not PICNIC sort of issue.

Started using the app last week. It was easy to pair my Galaxy S9+ Smartphone with my Polar H9 heart sensor and chest strap. I chose this app because it was rated the most accurate by a study published in March 2021 that examined 7 popular apps that measure HRV. The app is easy to use and the results are easy to understand. As the app collects more data over the days and weeks it gives you insights to manage stress and balance training and lifestyle.

The data is priceless but the app for android is often buggy and does not sync information from my oura ring. I followed the troubleshooting tips and still have the same problem frequently throughout the week when trying to sync my hrv data. After repeating the steps of setting the sync from oura and enabling the feature, the app will often try to measure hrv using the phone camera as well.

Wasted so many hours on this app. Trying to take a simple 5 minute HRV reading turns in to a massive time suck. You have to stay on the screen, or it will fail. If you get a pop-up notification during reading it will fail. Try another app if your time is valuable. RESPONSE TO DEV: Well the handful of people I know who've tried the app have all complained about the same thing...so "usually no need" seems very narrow minded.
