If there’s one thing the best fitness trackers do best, it’s hoarding your data. Whether it’s the Apple Watch 11 or the Pixel Watch 4, they silently hoover up gigabytes of information about your heart rate variability, sleep stages and step counts, then present it all in flashy graphs that look impressive but have limited practical use.
This week, Fitbit attempts to bridge that gap with the UK and iOS rollout of its personal health coach. Powered by Google’s Gemini AI, it’s a tad more sophisticated than the annoying notification that tells you to stand up once an hour. It’s a full conversational chatbot living inside the Fitbit app, designed to interpret that mountain of health data and build a fitness routine that adapts to your life, your equipment and your excuses.
