Do I need a smart watch on GLP-1s?

Not essential, but helpful. A smart scale is more important for tracking body composition. Smart watch adds activity and sleep tracking. Optional but motivating for many users.

Which is better: Apple Watch or Fitbit?

Apple Watch is more capable (ECG, blood oxygen, apps) but only works with iPhone. Fitbit is less expensive and works with both platforms. Choose based on your phone and budget.

Can smart watches track GLP-1 side effects?

Indirectly. Sleep tracking reveals sleep disruption. Heart rate trends may show stress. Temperature tracking (Oura) can reveal hormonal changes. Not medical devices but useful trend data.
