Fitness Smartwatch

Before getting this watch, I was using a basic timepiece and had to rely on my phone for everything, which was a hassle during concerts or when I was designing and needed to stay focused. After using it for a couple of months, it's been a solid companion—it keeps me connected and motivated with its health insights, though not perfectly. I appreciate the friendly design and how it blends into my daily life, but I wish it were a bit more precise with the fitness data. Overall, it's a good step up from nothing, but not the best out there. I'd rate it a 3 out of 5, as it does the job but has room for improvement.
- Pros: I really liked how long the battery lasts—I only had to charge it every week or two, which was incredibly convenient. Being able to see my messages and take calls right from my wrist without pulling out my phone was a game-changer, especially when I'm out and about. The watch works with any phone I've tried, and I enjoyed changing the display to show my own photos or different styles to match my mood.
- Cons: As it seemed to me, the heart rate tracking wasn't always accurate during intense workouts, and the sleep monitoring felt a bit off, not capturing when I woke up briefly. The design felt a bit bulky on my wrist, and while it handled splashes fine, I wouldn't trust it for serious swimming. Some of the sport modes were confusing and not very useful for my routine.
