Google’s Fitbit Air is super comfortable, but its AI coach is already hallucinating

Google’s new Fitbit Air is being praised as extremely small, light, and comfortable, with easy band changes and useful battery alerts.

The hardware review suggests Google is steering Fitbit toward a minimalist, data-focused fitness tracker.

But the new Health Coach in the Fitbit app has already shown accuracy problems, including claiming a run happened when it did not.

That early hallucination raises concerns about whether Google’s paid health coaching software can be trusted.
