> considering that every modern smart phone is both usb-c and waterproof? I doubt that modern smart phones are waterproof. Who would trust use their smartphone while showering or being in a bathtube (including submerging the smartphone a few centimeters into the water)?

I use my iphone in the shower all the time. Zero issues.

Well, I guess I am surrounded by a different kind of people ...

This is cool because we need more open competition for the app/identity locked ecosystems of sports related electronics like gps watches, bike computers, and action cams. I hate how none of the major brand ones will work without at least signing up for an account and most wont work at all without the manufacturers app.

Doesn't this also use its own app and services? The only "open" part of it I saw in the docs was that there's an sdk to write your own app that runs on the watch. Better than nothing, i guess, but not quite what I was hoping for.

Sadly I think you're right.

Do you have a particular hardware sensor requirement needed to clone the body battery function? I’m interested in developing this too but always resisted getting a smartwatch due to privacy concerns. If there’s something available that’s Gadgetbridge compatible I’d be very interested.

Good news; I'm gifting you with the fruits of AI, that has collated 200+ papers on the topic. I know, I know; this is generous. https://github.com/catigula/recovery

Incredible thank you!

I’ve had Claude work on a body battery type solution, which I’ll fully deploy over the coming days. It’s to manage and track brain fog/long COVID type symptoms and see if there’s correlation between foods eaten the day prior, resting heart rate etc and perceived brain fog. I’ll see if it’s possible to incorporate some of your work into my solution too.

It took GPT-5.6-Sol Pro about an hour of work; don't thank me :P

Some good points were already brought up in the comments (IP5X, USB C charging), but I have the feeling that it's also just not a good fitness tracker/smartwatch. I see a single unboxing of the watch from three weeks ago on Youtube and zero reviews on YT or websites. Just posts based on their PR release that it's available now. (Though some clearly already shipped.) Thus, it's unfortunately very likely that the produ…

I ordered the watch and just had it show up this week. The software side of it seems pretty immature (as you'd expect from first launch), but there's visible progress from the tiny team already. Appeals to me to be able to write my own activities and utilities, though I'm mindful of how far their "openness" extends. Nothing is locked down on the watch so you can dump the firmware, but they don't make the firmware publicly available AFAICT.

The hardware seems top quality (looking past the waterproofing concerns, don't love that). On first blush it seems like its in the same league as my Garmin Fenix 6 Pro for tracking though, with obviously way fewer features at this point. I intend to do a side-by-side with the Fenix 6 and a heart rate strap to compare HR and GPS to see how it shakes out under tree cover and bouncing around, but the hardware seems up for it.

Anybody have good recommendation of a watch that you can write your own apps for?

If you're looking for modern GPS, then this watch is really it right now. It's a pretty sparse landscape. Would love to hear about other watches, I ordered this one for exactly that reason as I couldn't find anything else that fits the bill.

Windows only for dev SDK simulator - not too sure many devs rockin Windows in 2026!

It's not Windows only, it runs on Linux just fine (not virtualized). It started Windows-only, but has quickly been patched up to run on Linux.

There are only about 400 units in existence, and they just started shipping June 30: https://www.kickstarter.com/projects/unawatch/meet-una-the-m... so it's been out for less than a month. That's why you've seen zero reviews on websites, it's an indie Kickstarter. They don't have the marketing budget of a big wearables brand. It has a GPS, IMU, and heart rate sensor: That's enough, obviously, to track activities, wor…

Not that it changes any of the rest of your comment, but from their Kickstarter campaign updates it seems like there are at least ~800 watches out there (and the public store just launched).

For me, I want an open API I can pull my data from. Last I checked, you have to be a business to use Garmin's API. Apple certainly doesn't let you. My goal is to have a cron that runs on my homelab that pulls my health data into a DB I own, from various sources, and visualize it in Grafana.

Apple certainly doesn't let you. There are several apps[0] off the top of my head that pull data from Apple's HealthKit. Apple even has a framework for it: HealthKit. That said, I've never written to that API myself, but it observational evidence indicates that you can pull data from Apple just fine. The app I use to pull data off Apple and ship to Strava says as much. [0] RunGap and HealthFit

Oh yeah, I should've clarified, I mean via a REST API. I thought about building an app for myself to do what I wanted to do, but it's frustrating that I can't just set up a Cron on my homelab to pull my data.

Unless I'm missing something and HealthKit does provide this.

I ran into the same issue when building ProForta.com. My solution was to build a companion app that pulls data (including Garmin) via Health Connect. Right now, it seems that every hardware platform from Oura to Garmin is trying to build their moat around user's data. That's not OK - users need access to the combination of all their data to derive meaningful health benefits. Thats the guiding principle behind lifecar…

I'm glad you agree re: Oura/Garmin's tactics. Thank you for building on principles!
