Current fitness tracking setup
Fitbit Air - Newest toy in town for day to day usage.
Coros HRM - For my runs and strength training sessions.
Garmin - For my runs and strength training sessions.
Polar H10 - For my runs and strength training sessions, although I prefer Coror HRM more lately because it's a bit better in terms of logistics.
Got the Fitbit Air from US for ~11k in a week's time.
I like the Fitbit Air so far but would probably get the Garmin Cirqa (if it's not priced too high because I'd like all my data in one singular eco system), but I think Fitbit Air is good for general recovery insights. I've noticed that my RHR on Fitbit Air is slightly higher than Garmin but that might be because I haven't had the chance to have relaxing days so far with Fitbit Air so that might be causing that.
The Health Coach feature is useful to me as I train a lot and have a log going on with Gemini anyway. This way I can just look into my effort without exporting data (in form of screenshot, etc.) directly from the Health Coach. I don't use my phone's GPS for the distance, etc. as my Garmin does that (I also don't like to carry my phone while running), but it's estimated distance is surprisingly accurate. The HR also aligned with my bicep band based HRM.
