Oura Ring Gen 4
The Oura Ring Gen 4 is a titanium smart ring that tracks sleep stages, heart rate, temperature trends, and daily readiness, then rolls it all into simple morning scores. It shines as a low-friction habit tool: you wear it, forget it, and the app quietly builds a picture of what actually helps you sleep. The honest knock is cost - the ring itself is not cheap and the full experience sits behind an ongoing membership fee. Buy it if you will genuinely use the trends to adjust your evenings; skip it if a bedtime alarm and a consistent schedule would get you 80 percent of the way there for free.

- Detailed sleep staging, temperature trends, and readiness scores in one clean app
