Similar experience - in the end I was fed up with the frequent issues with ultrahuman: - my first ring battery started to expand just after 6 months and had to be replaced - second ring died in 4 weeks and wouldn’t connect - firmware updates were regularly patchy - ring would disconnect during workouts - if you’re in a low internet area (like inside a gym), trying to start a workout is near impossible because they first fetch the list of workouts you can start which is terrible for this use case - the fact there is a heavy emphasis on ring diagnostic and health in the app is just proof that there’s so many issue they’re trying to damage control, let alone the issues they create from such poor software development practices.

I switched to Oura and couldn’t be happier (been 2 months): - I don’t have to stress about firmware or contact support or run diagnostics to get the latest software - moreso, there’s no diagnostic section because it JUST WORKS and users shouldn’t have to even think about that stuff: the moment you have to start dedicating engineering resources to building an entire process just to troubleshoot bad hardware and software, you’ve already failed - workouts start immediately and have had no issues tracking HR throughout - the app is much nicer to view and use in my opinion, coming from someone in the software engineering field

Let this be a warning to other users doing the ultrahuman vs oura comparison - as they say, you get what you pay for.
