The app stops working properly when the device goes to sleep during an activity(Edge 530). HR gets stuck and the estimated doesn’t get updated anymore. Happy to update to 5 stars once it’s updated. Working as expected with an Garmin HRM Pro chest strap, great work!

If this could work - will be great! But I didn;t manage to gewt it to work. Using Polar H10, Edge 530. Followed the instructions - chose BLE protocol. Not clear what to do with the filed that is labeled as: "BLE configuration" which says "Enter config for BLE communication", but you can't edit this, and what are you supposed to enter there anyway? Well, Idea is great, will be very useful if it works - good luck - I'll follow your progress, and if it works - I'll be happy to pay for it.

Ich verwende eine Fenix 6X pro Solar und einen Garmin HRM pro. Verbindung zur Uhr BLE, zur App ANT+. Besser geht es nicht. Verbindung sofort und keine Artefakte. Einziges Manko, dass der HRM pro bei BLE zur Uhr keine Running Dynamics anzeigt. Wenn ich den HRM pro auf der Uhr auf ANT+ stelle und die App auf BLE, funktioniert Running Dynamics, aber Alpha1 nicht mehr. Dafür kann der Entwickler nichts, das liegt an Garmin, weil der HRM pro Running Dynamics nur mit ANT+ senden kann. Ich schalte auf der Uhr einfach zwischen BLE undANT+ hin und her. Vielen Dank für diese wundervolle App.

Previously I wrote a 2-star review for the idea and hope that I'd get help getting it to actually connect. Finally, it just started working with my HRM Pro intermittently. Some runs it connects, so it doesn't. When it does connect, my watch cannot connect directly until much later, so I don't get run dynamics and strap HR. While this is far from ideal, I would be willing to accept ditching dynamics and strap HR periodically when I want to check my thresholds using this app. Obviously, it would be better if I could get both, so I would just use this app every time, rather than having to switch. But the inconsistency with connection to the HRM pro (which is, based on reviews, a problem others are having as well), means that even this tactic is a no-go. Further, even in the case that the data screen was running during my run, NONE OF THE DATA WAS LOGGED. So I had an empty graph on Garmin Connect, so the data screen, at this point, is only valuable for the few seconds you can look down and watch it. The developer unfortunately never replied to my request for help here or in the email I sent to him using "Contact Developer." At this point, this app has proven more troublesome than it's worth, thus I have removed it from my watch's running profile. I am holding out hope that one day I will actually get a reply with help (DEV, PLEASE!), or an update will fix things...until then, I stand by two stars.

Be convinced that it would be a great app. However I remark some issues in the data. The result I obtained with Polar H10 HRM with my HRV logger app on android or with my the alpha HRV on EDGE 530 is totally different (i.e DFA alpha 1 = 0.4 at rest with 55 bpm for alpha HRV app and 1.34 for HRV logger). Did not test yet during sport. The difference between both is the connection (bluetooth work with my smartphone but impossible to connect the HRM to alpha HRV via bluetooth). Maybe a problem of signal noise with ANT+ ?

He invertido en un fénix 7, he invertido en una banda polar H10 todo ilusionado, me he visto vuestro videos de configuración con Garrido que me cuesta entender. Y estoy desesperado, artefactos en todo momento, carreras de recuperación casi andando y el alpha a 0,4-0,5. O algo no estoy haciendo bien o algo funciona mal. Me cuesta entender en el reloj como configurar la iq por Ant pero el reloj por Bluetooth… yo creo que lo hago bien pero ya tengo dudas

I've finally managed to connect using BLE. I had to remove the ANT+ connection from the watch for it to work. So, essentially, this data field needs exclusive access to the HRM-pro. You either have alpha data or Garmin Running Dynamics data Ina running activity. Not both. Fenix 6 pro + HRM-pro.

You can connect alphaHRV in BLE mode and your watch in ANT+ mode. Use contact developer option if you need some support

this won't connect to the Edge 530 via ANT+ for some reason. Just says searching...

I was able to get the HRV data, twice, using ANT+ (Fenix 6 Pro + HRM-Pro) after deleting the band from the watch, but on both the activity missed the HR data from the band (it recorded from the optical sensor on the watch) and all Running Dynamics metrics, i.e., the HRM-Pro was connecting exclusively to alphaHRV. Every subsequent attempt to record HRV data, the band connected exclusively with the recording on the watch (all Running Dynamics metrics and HR appeared on the Connect activity - but alphaHRV never got data) All my attempts to make the BLE mode work with alphaHRV failed. I would appreciate help recording both data (Running Dynamics+HR and HRV) simultaneously.

Buenos dias. Queria saber si en EL VALOR DE ALFA 1 Y SU EVOLUCION QUE SE MUESTRA DE FORMA CONTINUA UNA VEZ RECOJIDOS LOS DATOS INICIALES NECESARIOS. (Extraido de la info de la app) la pregunta: si es importante mientras que recoje estos datos quedarce sin moverce (aproximadamente por 2 minutos) antes de la actividad o no importa.

Muchas gracias Iñigo por crear un campo de datos tan interesante. Ahora a probarlo y “estudiarlo”

I am very happy with the progress of this Field. The developer continues to work hard at optimizing the math, following the science. It’s definitely still a Beta product, but it is improving almost every release. Thank you - your work is important.

Lo uso en el Garmin Edge 1030 y va muy bien. Para otras actividades que no son el ciclismo, cómo el correr, uso el Fénix 5x. Ahí existe el problema de que si quieres usar la dinámica de carrera que usa Garmin solo es posible con el protocolo Ant+, y la aplicación no he conseguido usarla en modo BLE. Por lo tanto , tienes que elegir el poder usar la aplicación o la dinámica de carrera. Mi banda es la HRM-Pro de Garmin.

Siendo que el HRV es un modo de analizar el estado del sistema nervioso, ver datos DFA en tiempo real me parece fascinante, no solo por la influencia del esfuerzo en los entrenos y en las carreras sino por como influye tambien en el rendimiento el estado emocional de la persona.

As noted by another user the app will not pair with my Edge 530 using BLE. Ant+ does work but the reported Alpha1 does not correlate with post-exercise results from Kubios. Since there is no clarity re: what parameters are used for analysis and how data are filtered it is hard to rely on the results.

Garmin530 w/Dual HR monitor. Was able to get this version to work. Worked great for my most recent threshold workout, trying to keep within the 0.75/0.5 bands. I use AIEndurance training plans.

Could be good but so rarely connects to hrm-Pro that is useless. Out of 10 sessions once have I seen that works alright. Also the figure itself is so volatile that is meaningless, some 10-30 second smoothing would improve usability.

I have a Garmin Edge 530 and a HRM Dual HR monitor (BLE and ANT+). I can't figure out how to connect it so the Garmin app works. I've tried both BLE and ANT+ connections with the HRM on the Edge, as well as in the Connect IQ settings. Any suggestions for specifically how to connect would be greatly appreciated.

I am so excited for this datafield! It is one of the few apps/data fields in the IQ store that really adds functionality to the device. I find the alpha1 measurement very interesting, it is great that this now works on a garmin directly, without having to carry a phone. I still have some issues getting it to work correctly but I am sure this is mostly related to my input data, not the data field. While doing an easy run, the value fluctuates between ~0.4-0.6 which is much too low. I am using a Polar H10 strap, with a Wahoo Tickr sensor. Do you think it is likely these issues are related to the Wahoo Tickr sensor? Thanks for the help and keep up the good work!

Up to what I know, Wahoo tckr is not providing adequate RR data for DFA-a1 analiysis

Good job, seems promising! I can connect to my 830 with ANT+ but I can't manage to get it working with BT. On the other hand, with my Fènix 6 it connects with BT without any problems.

February 18, 2022 | Version 0.9.9

It works with ANT+ but not with BLE+Fenix 5x + Viiiiva. Not to mention my doubts on the pairing/operation. 1) “Use CLOSEST option when you pair first time a new sensor “ . Where/When does this pairing occur? In the app settings or in the screen page? While adding the page screen or after right before start an activity? 2) you mentioned that when changing comm protocol the app should be restarted. How? Tks.
