Google’s Pixel Watch 5 dives deeper into AI and health

The $399 Google Pixel Watch 5 isn’t astir the hardware. Sure, there’s a caller satin pyrite lawsuit finish, a fewer caller strap colors, and a Steph Curry Special Edition. Under the hood, there’s a somewhat faster Qualcomm processor and an itty-bitty artillery bump. There’s a $50 value hike from past year, too, because the Pixel Watch 5 isn’t immune to RAMageddon — nary of america are. Otherwise, nary 1 would blasted you for looking astatine this watch and reasoning perfectly nothing’s changed. That’s because the large updates this twelvemonth are each software-based.

This isn’t a immense astonishment considering Google’s Fitbit Air motorboat successful May. And aft seeing immoderate Pixel Watch 5 demos, it’s clear this year’s refresh is furthering the AI and proactive wellness themes that Google introduced earlier this year.

Health and fittingness features relationship for the bulk of the updates, but Gemini connected the wrist gets a fewer cardinal improvements. You tin now usage it offline for elemental tasks for illustration starting timers and launching apps. (Though I noticed successful my demo it was notably slower erstwhile doing this offline.) Gemini will besides beryllium much proactive successful making suggestions. One illustration I saw: a matter asking for my readiness brought up the action to cheque Google Calendar from the wrist. Likewise, there’s now an icon correct connected the watchface that surfaces real-time accusation for things for illustration timers, Uber ETAs, and workouts. Meanwhile, the pinchy pinch and wrist-flick features came via a software update to Pixel Watches successful December, but they’re overmuch much afloat integrated into the UI pinch WearOS 7.

You tin besides usage AI to make watchfaces. I created a watchface featuring “fat cats and an elegant font.” It didn’t quite do that. The fat cats weren’t characters, truthful overmuch arsenic pleasantly plump, cat-shaped timepiece numbers. It’s a gimmicky measurement to shoehorn the Nano Banana exemplary onto the watch… but if that’s your thing, it works.

Now for the wellness stuff. The astir caller update is Breathing Emergency Detection. It’s an hold of past year’s Loss of Pulse feature. When the watch detects a terrible driblet successful humor oxygen saturation (aka SpO2), it’ll trigger a telephone to emergency services and your designated emergency contacts. (A abrupt driblet successful SpO2 whitethorn bespeak you’re struggling to breathe.) To minimize mendacious positives, the watch uses a operation of bosom rate, motion, and altitude sensors. While I didn’t get to spot the characteristic successful action, I was told astatine my demo that the characteristic won’t footwear successful unless SpO2 drops to astir 83 percent — truthful a significant alteration — for an extended period. It besides disables erstwhile the watch determines you’ve been dormant for 30 minutes to mitigate mendacious alarms linked to debased SpO2 from slumber apnea aliases broadside sleeping. The characteristic besides isn’t intended to beryllium utilized by group pinch preexisting aliases chronic respiratory conditions; it’s much for flagging acute instances wherever a personification whitethorn person stopped breathing. It’ll beryllium disposable connected some the Pixel Watch 4 and 5 successful Europe astatine launch, and is pending clearance from the FDA successful the US.

A little high-stakes characteristic is that the Pixel Watch (and Fitbit Air) will besides way nightly slumber breathing value and supply monthly updates. The thought is to spot really your regular trends effect respiratory wellness astatine nighttime complete a longer clip frame.

Two different wellness features are Blood Pressure Trends and Insulin Resistance Trends. First and foremost: Neither of these is diagnostic. Both are wellness features intended to usability arsenic “check motor light”-type warnings, require a minimum of a week’s worthy of data, and emblem trends monthly. They won’t beryllium disposable correct erstwhile the Pixel Watch 5 launches; rollout is presently scheduled for September. That said, these features will besides travel to the Pixel Watch 3 aliases later, arsenic good arsenic the Fitbit Air.

With Blood Pressure Trends, the watch will show humor travel utilizing the optical bosom complaint sensor, arsenic good arsenic mobility sensors. That information gets fed into an AI exemplary to estimate the style and velocity of beat waves walking nether the tegument to approximate whether your humor unit is trending higher aliases lower. (There will beryllium nary nonstop systolic aliases diastolic measurements.)

While we’ve seen different wearable players for illustration Apple and Whoop tackle humor unit insights, Google’s effort astatine non-invasive insulin guidance discovery is marque spanking new. Insulin guidance describes a information successful which your assemblage doesn’t metabolize nutrient effectively. The pancreas has to nutrient much insulin to utilize humor glucose, and untreated, it often leads to fatigue, stubborn weight gain, and eventually, Type 2 diabetes. This characteristic would passively estimate whether your insulin guidance is trending higher aliases little period to period based connected signals for illustration bosom rhythm, slumber quality, and regular movements. To validate the algorithm, Google says it tested the algorithm against humor draws and published its findings successful a peer-reviewed study successful Nature.

Again, this is not noninvasive humor glucose monitoring. As pinch Blood Pressure Trends, location are nary nonstop readings involved, and this isn’t a screening characteristic for diabetes. It’s conscionable flagging erstwhile your manner trends bespeak sustained metabolic accent complete a monthlong period. Even so, I’ve spilled a ton of ink connected the decadelong process for maine to get diagnosed pinch insulin resistance. It tin stay asymptomatic for respective years, it whitethorn not show up successful regular metabolic tests, and a accepted test involves nagging doctors to trial fasting insulin and glucose via humor draws. We’ll person to spot really this characteristic useful successful existent life, but it’s perchance huge if it useful well.

That’s health. Google isn’t slacking connected the fittingness beforehand either. Fitbit and Pixel Watch users person griped for years complete dubious GPS maps from outdoor activities, particularly successful municipality areas. Last year, Google introduced dual-frequency GPS. This year, it’s making the bold declare that the Pixel Watch 5 will outperform the Garmin Fenix 8 and Apple Watch Ultra 3 by utilizing outer and upwind position data, arsenic good arsenic 3D models of buildings from Google Maps, to “correct” GPS information utilizing AI successful post-processing. Shots fired.

Google is besides bringing AI-generated spot training plans to the wrist. This characteristic is already disposable pinch Google Health Premium, but the quality is that you nary longer request the telephone to log reps aliases move connected to the adjacent exercise. At slightest based connected my demo, this seems for illustration an evident and smart move fixed the renewed accent connected spot training successful the GLP-1 era.

All of these wellness updates are meant to provender into the Google Health app’s AI coach (which requires a Google Health Premium subscription). As I wrote successful my Fitbit Air review, Google’s AI coach is the champion of the batch — but that is a remarkably debased barroom astatine the moment. AI wellness remains a activity successful progress, and Google’s coach is nary objection — but truthful acold these updates are a savvy operation of perchance adjuvant and smart for building a semipermanent AI wellness roadmap.

The Google Pixel Watch 5 is disposable for preorder starting coming and arrives connected shelves August 20th. The Steph Curry Special Edition will deed shelves September 3rd.
