Google Health's mistakes are a grave warning for Apple’s new AI-powered Health app

Any users of the best Fitbit devices that were watching Apple’s iPhone Duo event yesterday might have felt a chill of all-too-familiar dread during the company’s glitzy keynote presentation.

That’s not because Apple announced some sort of killer smartwatch feature that will bury the Fitbit range alive.

No, it’s because viewers got to see Apple’s new plans for its Health app, which now comes with an AI-powered makeover that will likely stir up some painful emotions for many Fitbit fans.

Of course, adding AI into an app doesn’t automatically doom it.

But the parallels between Apple Health and the Google Health app that Fitbit users have been lumped with — with all its wild hallucinations and crazy wellbeing inaccuracies — is undeniable.

Indeed, if the Fitbit experience is anything to go by, there’s a risk that Apple customers could be in for a bumpy ride.

Coming to your iPhone (Image credit: Future) Why might Fitbit fans be ringing a Google Health-shaped alarm bell? Well, Google-owned Fitbit announced a total overhaul of the companion app for its wearables back in May 2026 — and it was almost immediately unpopular.

The rebranded app was accused of being “unbelievably bad” amid missing features and confusing user interface decisions that made the app much less enjoyable to use than the one it replaced.

But that was just the tip of the iceberg.

As the weeks and months rolled on, social media started overflowing with user complaints directly squarely at one target: Google Health’s AI assistant.

This tool is meant to analyze your wellbeing data and make suggestions on ways you can improve your fitness and live a healthier life.

The problem, though, is that the AI seemed to frequently go off the rails.

I’ve written about how Google’s AI has been giving people “unhinged” fitness advice , feeding them “nonstop lies” and spinning up completely fictional food-tracking metrics .

It’s a real concern and has proven to be a tremendous source of frustration to anyone unfortunate enough to have to use it.
