After using the APPBYER Fitness Tracker for a few weeks, I’m genuinely impressed by its sleek design and long battery life. The 1.10-inch AMOLED screen is crisp and responsive, making it easy to navigate through menus even during workouts. Charging lasts up to 10-14 days, which is a huge plus for someone like me who hates constantly plugging in devices.

The heart rate, blood oxygen, and sleep tracking features are handy for keeping tabs on my health. However, the sleep tracking isn’t perfect—it sometimes misinterprets my pre-bedtime stillness as sleep. A manual adjustment option would be a game-changer here.

I love the waterproof feature (5 ATM), but I’d be cautious around chlorinated pools since prolonged exposure might wear down the seals. The band itself fits comfortably and stays put during runs, though one reviewer mentioned it bruised their wrist bone—so sizing might be an issue for some.

The app integration is smooth for basic tracking, but beware: some users reported aggressive subscription prompts. I didn’t encounter this myself, but it’s something to keep in mind if you’re averse to paywalls.

Overall, this is a great budget-friendly fitness watch with solid core features. It won’t replace high-end smartwatches, but for step counting, heart rate monitoring, and sleep insights, it delivers excellent value.
