A Smart Ring

not just a health tracker

⚠️ This project has been discontinued. The development and production cost for a reliable smart ring are too high for a side project. We decided against running this project as a full-time venture. Feel free to send an e-mail if you have any questions about what we learned.

We are a team of tech enthusiasts from all across the world. Looking at the smart rings on the market, we were disappointed. Products lack utility, are low quality and definitely not hackable. We want to change this. We want to build a smart ring focused on function. That stays open, without any subscription.

All you expect, no Subscription
