Apple Health AI Revamp Draws Warning From Google Health's Fitbit Missteps

TechRadar reported that the parallels between the two products are difficult to ignore. Google-owned Fitbit announced a complete redesign of its wearable companion app in May 2026, and the rebranded Google Health app was almost immediately unpopular. Users called it "unbelievably bad," pointing to missing features and confusing interface decisions that made it less enjoyable than the app it replaced.

More serious complaints centered on Google Health's AI assistant. The tool is meant to analyze wellbeing data and suggest ways to improve fitness and live a healthier life, but TechRadar reported that it frequently went off the rails. It gave what the article described as "unhinged" fitness advice, fed users "nonstop lies" and generated completely fictional food-tracking metrics, TechRadar said.

TechRadar argued that such patchy performance matters more in a health app than in other software because the AI is making suggestions that can directly affect physical wellbeing. For Apple users, the risk is that a similar AI feature may be coming to the iPhone through the Health revamp, which Apple says will arrive "later this year."

Apple's strong track record and cautious use of large language models could help, but TechRadar noted that Apple has also turned to Google for AI. After falling behind in the AI race, Apple enlisted Google's help for Apple Intelligence. That means the same AI models that performed badly in Google Health are now supporting Apple Intelligence, and with it, Apple Health, according to the article.

It is not clear how Apple is using Google's models inside the Health app. TechRadar said it does not know whether Apple has modified the models to its own tastes or imported them wholesale. Apple's website states that "all of our health innovations are subject to rigorous scientific validation and are developed with clinical experts from start to finish." Apple has also emphasized encryption, privacy and security for sensitive health data.

TechRadar said Apple would have noticed the backlash against Google Health and is unlikely to want the same kind of feedback from its own users. Even so, the article said, there is no way to know for sure until the new Health app becomes available. Until then, Apple users aware of the problems suffered by Fitbit users face an anxious wait.

Editor's Summary Apple's AI-powered Health app revamp has drawn warnings that it could repeat problems seen with Google Health, where an AI assistant produced inaccurate fitness advice and fictional food-tracking data. Apple says the app will arrive later this year and stresses scientific validation and privacy, but its use of Google AI models leaves questions about how the health features will perform.
