Short answer?

Take ScanWatch Nova if you weight buyer ratings; take Sense 2 if the AI ranking, 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 (ChatGPT · Claude · Perplexity) 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
  • Battery lasts three to six days with quick charging
  • Physical button replaces the unreliable capacitive touch sensor from the original
  • AMOLED display delivers vibrant colors and remains readable in sunlight
Reviewers push back
  • Many health features require a Fitbit Premium subscription to access in-depth metrics
  • Runs Fitbit OS instead of Wear OS, limiting app selection and smart features
  • GPS tracking can be inaccurate, sometimes registering five percent error and phantom paths
if this watch was running the wear OS you could have just kissed goodbye that kind of battery life

On Sense 2: Reviewers disagree on the EDA scan's usefulness—one calls it gimmicky and unhelpful, while another describes continuous body-response tracking as a meaningful improvement over the original on-demand method

This has been an excellent purchase - smart-looking, whilst quietly and unobtrusively recording all my data at the same time. I didn't want a watch that was going to be flashing and grabbing my attention all the time, but I do like to know how I'm progressing towards my fitness goals. This does everything and looks good at the same time. Battery life is great, lasting many days but also changing v JamesO · argos.co.uk
