Oura Ring 5 Shrinks 40% as Dexcom Cuts CGM Size by 50%

Summary
Oura’s newly unveiled Ring 5 is 40% thinner than Ring 4, while Dexcom said in May it reduced the size of its latest continuous glucose monitor by 50%.
The smaller designs reflect a push to make health trackers less noticeable and easier to wear continuously, with companies betting that discretion improves long-term use.
Oura said miniaturized LEDs, a redesigned battery and refined algorithms let the slimmer ring extend battery life to 6-9 days from 5-8 days.
Analysts say that shift is possible because most health trackers mainly collect data and send it to phone apps, where the software delivers the core health insights and diagnostics.
The broader industry goal is an always-worn device that blends into daily life while building enough data to flag anomalies and support FDA-cleared health features.
