I use this to track my sleep mainly, but love the altimeter, compass and barometer temperature functions. I understood the limitations of those functions and really just thought it would be a fun toy as I travel for work. So far I'm happy with the watch and the information it gives me. However the link with the app is kind of clunky, there are some missed opportunities. sleep tracking should take occasional o² readings, the altimeter and barometer should be able to send live info to app.

It covers the basics well, with 2 things can be better: 1. I already own the 5600 with fitness data, didn't want to see the 'ad and buy' page, want to access my data most of the time directly. Option to pick the starting page when opening the app? 2. Android's Google Fit sync is missing. It's 2024, why can't I sync up to my Android phone?

The old G-Shock app was fantastic, with intuitive features that made managing my watches a breeze, especially for frequent travelers like me who switch time zones several times every month. The new app, however, feels cluttered with marketing and seems more focused on data collection than functionality. I’m disappointed enough to consider selling my G-Shock collection, which I never thought I’d say. I certainly will not be buying any new ones.
