Reviews for HRV4Training

This is a fantastic app. I am using it on a Samsung S7 phone, which has a builtin heart rate (HR) detector (IR), so I dont have to use the flash. So I may be biased on its ease of use in collecting data (no burnt fingertips that is). First and foremost, this app seems […]

Data transfers with Oura ring is hit and miss, every morning I wonder if the Link will work wit my Oura ring. Have to press on the button multiple time for the link to work. Sometimes HRV4TRAINING only pick up the data 12hrs + later. Now it ain’t work on over 2 days. If you […]

The app worked fine for about 3 days but now no longer connects to the Oura ring to import HRV data. I tried tweaking the settings and re-authorizing Oura, but nothing worked. Had to reinstall to get it working again, but this means I lost all app data and had to set the app up […]

This measurement app gives a lot of insights in my fitness level and things that influence it. Also the knowledge base on the website with explanations and researches are very interesting and helpfull. I now make sure i don’t overtrain too much, something i usually do. But now i can see what the effect is […]

Since my Samsung’s Android software was updated this app became just a keeper of nearly 3 year’s worth of data. Everytime I select an ANT+ HR strap, it says go to store and get ANT Utilities app (which and several others were installed). Fix your app @Marco. The problem seems to be with your app […]

Impossible for me to get reliable readings using the camera method. Many mornings, I just give up after five or six attempts (each taking a full minute!). Maybe it’s just my fingers, or my phone (Pixel 6a). But it’s certainly unfortunate that you have to pay the full price before you can even test whether […]

I want to love the app, but ridiculously buggy with a Garmin HRM Pro. I’ve tried everything they suggested, with de-activating Bluetooth, etc. Fitting the strap first thing in the morning is enough of a faff, but sometimes it will (literally) take around 20-30 attempts to get it to connect while telling me to “Stay […]

When it works its exactly what is needed for detailed HRV tracking and analysis for athletes. But that’s the main issue. I’ve tried their recommend HR straps and it takes 10mins mucking around to get a good signal, I’ve moved to oura and you spend half the day trying to get it to sync up […]

The measurements are frustratingly inconsistent, on some days I have to take 10 measurements to get a reading, on some days I even can’t get a reading. I’m using phone camera mostly (Google Pixel 4a), but it doesn’t even work always with a Wahoo HR strap. When it works, it’s a good app – you […]

Android 15, need to manually adb shell appops set –uid com.asma.hrv4training MANAGE_EXTERNAL_STORAGE allow to have data export working and the message is really misleading please update … oh, and then the update drops the Dropbox like nobody used it or something. Sure, easier this way instead of implementing API calls.

Awesome app! Have been using it for a year daily and it’s such a great app! It is integrated with Trainning Peaks and Strava. Easy to read info from each and quickly sync with Training Peaks! Allows us to do backups to Dropbox/Email. A great plus are the insights provided inside the app, where we […]

(Note: I use a Garmin HRM-Dual chest strap sensor rather than the camera function.) The data presented is certainly interesting and I’m hoping it helps me to train and avoid the dreaded overtraining. The app itself is a tad bit basic and while all the data and functions can be found, I’ve found it’s UI […]

I couldn’t get an optimal recording quality with my HR chest strap. I appreciate that the app actually told me that, rather than taking the easy road and acting like the read quality was fine. I’ve been able to get optimal readings using just the phone and the app’s guidance on getting better readings. But […]

Doesn’t sync with Google Health Connect / Fit / Fitbit data, so I have to use the camera to take readings. The readings don’t work on a Pixel 10 because the camera and flash are not next to each other. This is horrible. Don’t spend the $12. How can I request a refund?

Strava integration broken on my device due to what looks like the app not complying with modern security standards (Google Auth also broken), meaning useful HR data can’t be imported. Also TP export has broken, possibly linked to when I missed readings for a day, and hasn’t worked since. Developer uninterested when contacted. Rubbish. edit: […]

Nice looking intuitive app with all evaluation I need right now. However, lack of integration with health connect/Fitbit is a big disadvantage. I need to maintain too separate apps and evaluate the data separately (or transfer manually). it seems that the integration with Google fit was maintained before why was it discontinued? is there a […]

This worked very well when first installed a month or so ago, but has recently become somewhat unstable. It is now taking 2 – 3 readings to get a merely “good” result instead of optimal which used to be the norm. Whereas I used to be able to swipe between the HRV and rMSSD reaings […]

I really wanted to like it, but the app is unusable on a Google Pixel 8 Pro. Not sure it’s the distance between camera and flash, but the readings are always poor quality. At the price point for the app, you would wish they have a better tracking of which phones are truly compatible with […]

Used to be great until something started happening with the Oura Sync. Devs were responsive but ultimately never solved the problem. The quick fix of “backup all” on Oura worked a few times, clearing caches worked a few times. Now nothing is working and I’m losing days of readings because I need to do this […]

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 […]
