Description
According to recent research (see below) the FatMaxxer Android app may help you to exercise at the optimum effort level for fat burning, measured using just a Polar H10 heart rate strap.
FatMaxxer provides real time Detrended Fluctuation Analysis of your inter-heart beat intervals to give real time feedback of alpha1 (⍺1) in real time. There are promising signs that running or cycling at ⍺1 = 0.75 corresponds to the first ventilatory threshold "VT1" or roughly FatMax which would otherwise be measured in a lab on a treadmill using gas exchange techniques (https://www.frontiersin.org/articles/10.3389/fphys.2020.596567/full).

FatMaxxer will only work with the Polar H10 (and possibly H9).

Tried it out for the first time on my 2.5 hour run and I must say it certainly kept my heart rate in my Maf zone, which I was hoping Hatmaker would prove to be wrong lol. Brilliant app. Highly recommended. Although it is stipulated that you must use it with Polar H10 some say it also works with H₉, but I would say use H10 as it can link up with 2 devices using recommended Bluetooth, so heart rate data was still gone to my Garmin as well as fatmaxx. FatMaxx notifications picked up by Garmin.

Do not start at OnePlus 7TPro (Android 11) I spent $2 and get NOTHING.

Not working most of the time. Zero support. Went back to using HR alone
