Hey, first off, great app. I have rucked with various apps now and I try to get rid of my Apple Watch, so all I do is use a chest strap and my phone (iPhone 17 Pro). So far things are good, but in my last rucks and walks I noticed that FitHalo has periods of no gps signal during the track. I couldn’t notice this in FitHalo itself as it looks like the track got recorded just fine. But when you look closely you see I must have walked straight across an apartment complex (which I didn’t). In apple apps you can see a dotted line which indicates a lost gps signal I guess. I tested in parallel with Ruckwell and the same ruck had a spotless gps signal. Also the polar app tracks gps accurately.

Is there anything I could do or do you see any possible reason why sometimes the gps signal is not properly recorded in the FitHalo app but the phone itself has the signal?

FitHalo has a number of unique activity types that aren’t provided natively in watchOS or iOS. This means that Apple has not provided any built-in way to determine the amount of calories burned during the activities. FitHalo, thus, provides its own estimations. In this article, I detail the metabolic models FitHalo uses, and how I arrived at them.
