Apple Watch Ultra 3 — One Week In (Runner’s Perspective)

I’ve been using the Ultra 3 for about a week now, mainly for running (1–2 hours a day, roughly 10h/week, 120km/week) plus strength training or yoga for about an hour daily. I’m very routine-driven: I work from home, never travel much, always home by 6PM, runs in the morning, workouts in the afternoo

The tracking features, ECG , the eco system are just perfect. Hoping for a smooth

Wearing an Apple Watch AND a Whoop?

Would not do Hume. Would research their quality and customer service/satisfaction and then stay far away. Tons of people wear AW and Whoop, I'm one of 'em. It's great. Overkill on some things but I couldn't test and commit to one, the other, or both without a year's worth of Whoop. Worth it for me p

How silly is it to buy Ultra if I'm not doing any sport activities at all?

I am planning to get Apple Watch Ultra 3 this Friday, but does it make sense to me if I am not doing any physical activities at all? (only for occasional walks around the city)

I want it just because of good integration with other Apple devices, much better battery life than regular models, and muc

AWU3 vs Garmin Fenix 8 - losing my mind over this GAS spiral 😅

Hate that this decision is taking up so much brain power, but here we go.

Context:

  • Had an Epix Gen 2 (non-Pro) with AMOLED and loved it - was originally an Apple Watch user.
  • Lost it. Now torn between the Apple Watch Ultra 3 and the Garmin Fenix 8.
  • What I actually plan to do: road running, trail ru

Is there an Apple Watch app that comes close to the Garmin ecosystem?

A comprehensive analysis by data scientist Rob ter Horst from the University of Vienna indicates that the Apple Watch Ultra 2 delivers heart rate readings with minimal deviations compared to medical-grade equipment. In tests using the Polar H10 chest strap as a control during various activities, the

Fenix 8 and Apple Watch Ultra 3. What I think coming from Garmin after buying the Apple one.

Hanging around to decide what to stick with: Fenix 8 or awu3.
What I really appreciate in the AWU3 is that it is part of my Apple ecosystem (iPhone, MacBook and AirPods), the screen quality, smoothness in animations and its focus on health, especially the compared metrics about temperature, sleep,

Took me embarrassingly long to realize my HR readings were off because of where the watch was sitting

I move my Apple Watch Ultra 3 (AW3) about an inch or so up my arm, away from my wrist and the measurements are incredibly accurate. When I say accurate I am comparing the results after going through 3 months of cardiac rehabilitation; I had mitral valve repair surgery. I wore a 3 lead ECG while exer
