The Ultrahuman Ring Pro builds on the Ultrahuman Ring Air's features with several key improvements, including an impressive battery life of up to 15 days, which is more than twice as long as the Air.

Food logging can be done in a few ways, including searching a database, scanning barcodes, or using AI-based camera analysis. Simpler items like eggs and fruit are identified well, but complex meals can be frustrating due to lighting and AI limitations.

According to a growing body of research, the circumference of your neck could be an indicator of a higher likelihood of serious metabolic diseases, including heart disease, diabetes, and sleep disorders. Another troubling fact is that even if your body mass index (BMI) index is healthy, just how large your neck is could still be a determining factor in your predisposition to developing these conditions.

Since 1990, the incidence of hypertension has increased globally, with up to one in three adults worldwide affected by it. Most of those people have no idea they have it. If people could diagnose and monitor hypertension at home, the World Health Organization estimates that up to 76 million lives could be saved with easy fixes, like stopping smoking or adjusting diet.

Meta is building a smartwatch, and it wants to know your heart rate, your sleep patterns, your activity levels, and whatever else it can pull from a sensor pressed against your skin all day. The device is codenamed Malibu 2, it's targeting a 2026 launch, and by most accounts it sounds like a perfectly competent health wearable. The problem isn't the hardware. The problem is the company attached to it.

Google announced on Tuesday that the public preview of Fitbit's AI personal health coach is rolling out to iOS users in the U.S. as well as both iOS and Android users in the UK, Canada, Australia, New Zealand, and Singapore. It initially launched in October, when it was only available in the U.S. on Android devices. To try out the feature, users need to have an active Fitbit Premium subscription and use a Google account to sign into the Fitbit app.

We use the IMU sensors to detect which exercise the user is performing and identify the period engaging in concentric, eccentric, or isometric hold. These are the three main types of lifting exercises; you might know them as contracting, lengthening, or static exercises. The Fort uses the wrist as a proxy for bar velocity, and the company is seeking FDA clearance and will also be pursuing large, third-party studies from independent labs.

January might be coming to a close, but the focus on wellness doesn't have to die with it. If anything, it's a good time to check in with those 2026 goals and see what you want to prioritise for the rest of the year. To that end, we've gathered some of the best deals we've seen in the past few weeks that will help you tick off every good intention you set this month.

Recent surveys estimate more than 6.7 million Australians - almost half of all workers, and the majority in Sydney, Melbourne and Canberra - work from home at least some of the time in paid or unpaid roles. With that increase in working from home, it's easy to spend too long sitting, which is now recognised as bad for our health.

The FlowPad looks like your run-of-the-mill menstrual pad but is built with a microfluidic diagnostic layer underneath that directs menstrual blood into biomarker zones for testing fertility, ovarian health, and perimenopausal hormones. The results of the test show up in Vivoo's app after a user scans the pad's results through their phone camera or enters them manually. The ethos behind FlowPad and Vivoo's smart toilet is simple.

Petal is a bra insert that uses bio-impedance sensors and electrical measurements to monitor blood flow near the heart. Because wearers position the insert right next to the heart, the device can capture more accurate readings than your typical smartwatch, Petal says. The device comes in one size and fits snug against each breast. It's made with biocompatible materials, including a soft European fabric and a polyurethane-coated interior.

Wellune looks like a small, sculptural lamp. A slender white stem curves upward from a flat circular base, blooming into a soft, rounded head that sits somewhere between a sprouting bud and a modernist desk light. The head detaches magnetically, which is a lovely detail because it turns setup into something almost playful. You hold this smooth, egg-like dome in your hand, place it on the stem, and it clicks into position with a satisfying connection.

"I heard a pop in my head, like a big bubble," she said. "I tried to scream, but it wasn't a normal scream. I knew something wasn't right."

By attaching near the ear, the device targets the auricular branches of the trigeminal and vagus nerves to regulate menstrual cycle symptoms and help the body return to a rested state. These nerves play an important role throughout the menstrual cycle and release estrogen and progesterone, two essential sex hormones. They also target muscle contraction, blood flow, digestion, and more, a few body functions that change during a period, which explains the increase in cramps and tightening of blood vessels.

If there's one thing that stops people using their smart rings over the long term, it's the battery life. After all, they're so unobtrusive, it's easy to forget to drop it on the charging plate every few days. It doesn't take long for your pricey gadget to become little more than a very expensive piece of jewelry.

VO2 max is an intimidating word for an easy-to-understand biometric: It's how well your body uses oxygen when you push yourself. Short for "maximal oxygen uptake," it's been the gold standard for assessing cardiorespiratory fitness since the 1950s. Until recently, it's mostly lived in research labs and elite training centers, helping coaches squeeze every last drop of performance out of elite skiers, runners, and cyclists.

Last Wednesday morning, I woke up and did what I normally do when I open my eyes. I grabbed my phone and checked my Oura app to see how I slept. This morning, however, Oura's home page looked a bit different. Unlike the sleep and readiness scores I usually see on the home page, a new message appeared on top. While no biomarker deviated strongly from my baseline, Oura's Symptom Radar feature warned me that my biometrics indicated "major signs of strain." It encouraged me to take it easy -- a tall task given that I was headed into the office for the workday.

When people breathe, speak, sing or clear their throats, their bodies are in constant motion. Air flowing through the lungs, the oscillation of vocal folds in the throat and the rhythmic expansion of the chest all produce tiny vibrations that carry valuable information about physiology and health. However, constructing a device that can capture all of these physiological signals has remained a challenge.

A tennis match usually starts with rituals you can set your watch by. A towel tug, a ball bounce, a glance at the strings. This year, a different ritual stole the first spotlight, because officials asked top players to take off a wrist wearable before they played, and the moment landed like a plot twist you did not order. This piece walks you through what happened, why it happened, and what it says about where tennis sits with athlete data right now.

Natural Cycles, the company behind a controversial FDA-cleared birth control app, is replacing its thermometer with a wristband that measures skin temperature, heart rate, and movement during sleep. The newly-launched wristband costs $129.99 and syncs with the Natural Cycles app, which uses an algorithm to determine a person's "daily fertility status." Users can already track their fertility by pairing an Apple Watch or Oura Ring with Natural Cycles, but the wristband could be an option for users who don't have either of these devices handy.
