It's fair to say Fitbit has been through a few changes in the eight years since I wrote about breaking up with the then-dominant wearable. Spoiler alert: I ran away with the Apple Watch and never looked back. Now here comes the ex with a new announcement, and, uh … I guess you'd say they've had some work done?

Fitbit was bought by Google for $2.1 billion back in 2019. The Fitbit co-founders left the tech giant in 2024, a few months before Google discontinued the Fitbit wearable altogether. The Google Pixel has become the default Fitbit smartwatch, and the Fitbit Charge 6 its sturdy old-school fitness tracker.

Meanwhile, the Fitbit app — where Google sells Premium subscriptions at $8 a month — has been loaded with new features. Now, whether you like it or not, those features include feedback from Google's AI, Gemini — or as it's called in its Fitbit flavor, Coach.

The company has trialed Coach via the Android version of the Fitbit app. The test expanded last month to iOS users — right around the same time Fitbit owners were required to have Google accounts, and the Fitbit accounts were discontinued.

That deadline for switching to Google has been extended until May 19, 2026 — doing little more than perpetuating the agony for old-school Fitbit users.

All of which, apparently, makes this the perfect time for Google to invite Fitbit users to trust the company with their medical data. "When your coach understands your medical history, its guidance becomes safer, more relevant and more personalized," the company wrote in its latest Fitbit announcement.

The company added: "you have control of your data and how it's used, shared or deleted. Your medical records, like other health data in Fitbit, is not used for ads." (emphasis in the original.)

And if you're wondering whether to trust that claim, note that the AI features in question aren't from Google alone. Requests for health records go to b.well Connected Health, an AI platform that aggregates health data from various providers.

Clear, the security platform you may know from the empty line next to the TSA queue at many airports, is another partner, allowing you to search for medical records using a valid form of ID and a selfie.

So, Fitbit, you're looking well, and I see you have some new friends. We must catch up sometime. Bring my medical records? Yeah, let me think about that. I'll let you know!

Like any book-to-film adaptation, Project Hail Mary makes some changes to its source material.

In most cases, Project Hail Mary's changes look like removing elements of Andy Weir's novel in order to streamline the film. For example, in the book, a key part of finding astronauts for the Hail Mary mission is determining whether they have a very rare coma resistance gene, all of which is missing from the movie. Another omission? A plan to power Astrophage production by covering the Sahara Desert in solar panels.

However, Project Hail Mary does make one addition in its final minutes that isn't in the book.

The film ends very much like Weir's novel, with biologist Ryland Grace (Ryan Gosling) living not on Earth, but on alien Rocky's (voiced by puppeteer James Ortiz) home planet of Erid. He's sent the Hail Mary's beetle probes back to Earth with instructions on how to breed the Astrophage-eating Taumoeba and save the sun. In the book, after Grace has spent years on Erid, we learn that the sun's luminosity has been restored, meaning Grace's research made it to Earth and humanity is saved.

However, we never actually see what that process looks like in Weir's book. In fact, we never return to Earth, as we're in Grace's mind the whole time.

The movie, on the other hand, does bring us back to Earth as the film winds down. It shows us its now-frozen oceans, a result of global cooling due to the sun's dimming. It also shows us what's happened to Stratt in the years since the Hail Mary launched.

Stratt's fate remains a mystery in the novel, although she believes that she'll eventually wind up in prison due to the extreme actions she took to get the Hail Mary off the ground. (The Sahara Desert plan, for example, proves an environmentally destructive resource drain, although it gets the job done.) The film takes a more optimistic approach, showing that Stratt is still alive and has received the beetles. Now, she's ready to start work on the next phase of Project Hail Mary.

"Quite honestly, I love writing Stratt," screenwriter Drew Goddard told Mashable while discussing Stratt's ending. "This movie is about three characters, really. It's a triangle between three characters, and we need to give her her moment."

Thus, Stratt's epilogue was born, granting us a hopeful glimpse into humanity's recovery effort.

Goddard continued: "That's what great about movies. You can cut away, whereas the book stayed with Grace. Once I put [the scene] in, no one questioned it. I was really grateful that they let us do it, because I thought it was really important to see her."

Project Hail Mary is now in theaters.

Project Hail Mary has shouted out Harry Styles so much, we might as well be calling it Project Hail Harry.

The sci-fi film's first trailer was set to Styles' song "Sign of the Times." Gosling then performed it during his Saturday Night Live monologue, all while Styles looked on. (Gosling also returned to SNL the following week to introduce one of Styles' musical performances.) Of course, all this Styles love stems from the fact that "Sign of the Times" appears in Project Hail Mary itself.

Based on the novel of the same name by Andy Weir, Project Hail Mary centers on a last-ditch mission to save Earth's dimming sun from an alien microbe called Astrophage. During an emotional scene in the lead-up to mission's launch, everyone involved, including biologist Ryland Grace (Gosling) and project head Eva Stratt (Sandra Hüller), gathers for karaoke. Nothing will soothe your worries about the end of the world quite like communal singing!

In the scene, the usually business-focused Stratt takes center stage to perform an almost elegiac take on "Sign of the Times." It's screenwriter Drew Goddard's favorite scene in the film, although he claims no credit for the Styles song choice.

"I had nothing to do with it," Goddard told Mashable in a video interview. "We knew we needed this sort of hangout scene. I call it the 'calm before the storm' scene."

Directors Phil Lord and Chris Miller suggested karaoke for the scene, and, Goddard recalled, just a few nights before shooting, they decided to try to get Hüller to sing in the film.

"She said, 'I'll only do it if I can do the Harry Styles song,'" Goddard said. "So it was Sandra's choice, which is insane to think about, because it lines up so perfectly with the point of the movie. It actually says 'breaking through the atmosphere,' for God's sake. I could not have chosen a better song. That's all Sandra. She picked it, and thank God she did."

Project Hail Mary is now in theaters.
