Fitbit's smarter coach

Fitbit is remaking its app around an artificial intelligence coach that talks more like a trainer and less like a dashboard. (blog.google) Google introduced the Personal Health Coach in August 2025 and began a U.S. Public Preview for eligible Fitbit Premium users on Android in late October 2025, with iPhone support promised after that first rollout. The coach is built with Gemini and uses Fitbit data, profile details and connected app information to answer questions and shape plans. (blog.google, blog.google, support.google.com) The original pitch was simple: tell the coach your goal, your equipment and your schedule, and it builds a plan that updates as your readiness, sleep and recent workouts change. Fitbit’s help pages say those plans refresh weekly and include targets for key metrics, while the coach can also answer follow-up questions in chat. (blog.google, support.google.com, support.google.com) Google spent early 2026 widening that experiment before sharpening it. On February 10, 2026, Fitbit expanded the Public Preview beyond the United States to Premium users in the United Kingdom, Canada, Australia, New Zealand and Singapore, and brought the preview to iPhone users in those markets and in the U.S. (blog.google) On March 31, 2026, Google added cycle tracking, mood logging, mindfulness tracking, a renamed stress score called resilience, and nutrition and water logging. That same update also opened parts of the Public Preview to people without Premium, while keeping features such as Ask Coach and custom fitness plans behind the subscription. (blog.google) This week’s seven changes push the coach further toward day-to-day guidance instead of passive tracking. Reports on the April 23 rollout say version 4.68 adds customized weekly targets, tailored workouts, manual plan edits, more natural check-ins, stronger daily motivation and more conversational guidance tied to individual goals. (droid-life.com, tech.yahoo.com, msn.com) The app already had the plumbing for that shift. Fitbit’s documentation says the coach can assess past workouts, preferences and conversations, then update a personalized plan each week, while Fitbit’s cardio-load system sets daily training targets based on the prior week’s strain. (support.google.com, support.google.com) The branding around it is moving, too. On April 23 and April 24, 2026, 9to5Google and Droid Life reported a new Google Health logo and store listings that briefly showed “Google Health Premium” in place of Fitbit Premium in some markets. (9to5google.com, droid-life.com) Google has not publicly said the Fitbit app is going away, but the direction is clearer than it was last year: Fitbit hardware still collects the data, and Google is increasingly packaging the value as coaching software. The more the coach can set targets, rewrite plans and answer in plain language, the less Fitbit looks like a step counter with charts. (blog.google, support.google.com, droid-life.com)
