After testing the anyloop Fitness Tracker for several weeks, I can confidently say it's a solid choice for those wanting a feature-packed smartwatch without breaking the bank. The large 1.69-inch screen is crisp and responsive, making it easy to navigate through menus and check notifications.

The heart rate and SpO2 monitoring work well during workouts, though I noticed slight discrepancies compared to medical-grade devices. Sleep tracking is surprisingly accurate, giving me detailed insights into my sleep cycles.

Battery life is impressive - I consistently got 6-7 days between charges with moderate use. The quick-release straps are convenient for swapping styles, though I wish more band options were included.

Where this tracker falls short is step counting accuracy. During side-by-side tests with other devices, it consistently undercounted by about 30%. The automatic sync feature could also be improved - you need to manually open the app to update data.

For under $50, you're getting excellent value: 20+ sport modes, customizable watch faces, and basic smart notifications. Just don't expect medical-grade precision from its health tracking features.
