Twitter co-founder Jack Dorsey builds sunlight tracking app. Called “Sun Day”, you can track the amount of IU exposure you get daily (Vitamin D exposure). Tap “Begin” in the app when you’re outside, and it tracks based on your location, the clothing you have on, and your skin type.

  • I actually love the simplicity of this. Sunlight exposure is one of the most underrated things in health. Yes, we’ve heard about it plenty from experts like Andrew Huberman, but people still ignore it. Sunlight exposure impacts your circadian rhythm, hormone balance, sleep quality, and more. But no one really thinks to track it like they do steps or macros. I like how “Sun Day” makes the behavior tracking pretty frictionless. Big fan of simple tools for tracking the fundamentals.

Ultrahuman unveils Blood Vision. At-home blood testing for over 100 biomarkers. With all the data syncing to the Ultrahuman app to visualize, understand patterns, and track progress. Along with integration to their smart ring, so you can see how sleep, heart rate, and movement trends correlate to your blood markers.

  • Ultrahuman is quietly building an entire health ecosystem. Blood Vision is just the latest piece joining their smart ring, CGM, and home health device. But the magic isn’t just that they have all these products. It’s that they all talk to each other. Sleep, glucose, movement, air quality, blood biomarkers - all integrated in one place for consumers. It’s exactly the concept of “Health OS” that Fitt Insider has talked about recently. The future of health isn’t just more data, it’s connected data that actually makes sense of your body as one system.

Form rolls out AR, Gorilla Glass smart swim goggles. Built with Corning Gorilla Glass, making the goggles scratch and damage resistant. In terms of the tech, the goggles have a customizable AR display for time, distance, pace, stroke rate, stroke count, calories, and more. With all data syncing to their app for post-swim data as well.

  • Story time. Two years ago I did a half Ironman. When training, the swim was by far my least favorite part. Partly because I sucked at swimming, BUT also because it felt so hard to track progress compared to running and biking. Plus, I beat my goggles to shit and they leaked constantly. So having damage resistant goggles AND live AR swim metrics would’ve been a game changer for me. I love what Form is doing here. They are really owning the smart swimming lane - making training more precise and more enjoyable.

Ōura unveils new nutrition and mental health tools. Including “Nutrition Level” in “Meals” that will give you a real-world view of how your meals are fueling you, focusing on fiber, protein, added sugar, and processing level. And “Burnout” tools to help users improve mental health and wellbeing.

  • For years, the extent to which consumers tracked nutrition boiled down to just calories and macros. To really drill into micronutrients and your specific needs, you had to do a lot of research, bloodwork, or hire an expert. One of my favorite benefits to AI advancement is how it makes previously hard to come by services more accessible for your average person. Snap a photo of your food, track the basics, but now we also get AI-powered feedback on how the food is actually fueling you. All integrated with your Ōura ring so you can also see how your health metrics get impacted. Again, a legit step toward a true “Health OS”.

Joe Wicks launches a kid’s animated physical activity series. Called “Activate”, it will be an online animated show designed to get kids moving and make fitness fun. Featuring 5 minute episodes that will include easy exercises, a gamified format, and music from popular artists.

  • Wanted to tip my cap to Joe Wicks. I love seeing people build products that push towards making kids healthier. It’s such a crucial stage in life, and the habits you form early can shape your whole future. I think it’s shameful that for as long as I’ve lived, the biggest brands in the world have been serving sugar filled cereal and brain rot entertainment to kids. So props to Joe Wicks for doing something for kids that is both entertaining and teaches them to move. More of this please.
