Are AI health coach subscriptions a scam? My verdict after testing Fitbit's for a month

ZDNET reviews the revamped Fitbit Premium, an AI-powered health coach integrated with Google’s Gemini that personalizes and adapts weekly workout plans using sleep, stress, and activity data from Pixel Watches and Fitbit devices; priced at $10/month or $80/year, it impressed with accurate strength training guidance and flexible plan adjustments via an in-app coach, though the reviewer notes limited long-term strength metrics and discomfort wearing the watch to sleep, concluding Fitbit currently leads rivals in all-in-one fitness coaching and that the subscription is worth it for committed users, with a public preview available and wider rollout coming.
