Short answer?

Take ScanWatch 2 if you weight the AI ranking and buyer ratings; take Versa 4 if reviewer scores and a lower price matter more. That's where they diverge — elsewhere they're close.

How this is made

Built from what 3 AI models (Claude · Perplexity · ChatGPT) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

Reviewers praise
  • Sleep tracking accuracy stands out among smartwatches, correctly capturing sleep stages, wake times, and even naps
  • Battery lasts five to six days with typical use, around two to three with always-on display and GPS workouts
  • Lightweight comfortable design at 24 grams, thinner than previous model, with water resistance to 50 meters
Reviewers push back
  • Music control and Spotify integration removed compared to Versa 3, forcing users to carry phones during workouts
  • Third-party app support eliminated, reducing functionality versus predecessor
  • Advanced health features like ECG and skin temperature sensors require upgrading to Sense 2
A capable fitness tracker with exceptional sleep tracking and battery life, undermined by the removal of music control and third-party apps compared to its predecessor.
— best for: Someone wanting straightforward fitness and sleep tracking in a comfortable package who does not need music control or extensive app ecosystem.

I love the Fitbit Versa 4. I started wearing the Versa, then Versa 2 and now the Versa 4. They’re great watches and will hold a charge for a good while……unlike my Apple Watch which needs charging every 18 hours. I love it especially to keep up with sleep quality, my steps and my heart rate. I also love that I can read my texts. This is a handy watch with lots of information to give.
