No. Never. Your data is yours — no monthly fees, no cloud lock-in, no ransom for your own biometrics. Every competitor either charges a subscription or forces ecosystem dependency. Sensora doesn't. You buy the piece once and own the experience forever.

5–7 days on a single charge for the ring. The bracelet and necklace vary by form factor and sensor configuration. For context: Oura Ring 4 averages 4–5 days real-world, Ultrahuman runs 3–4 days. We don't over-promise battery life — the 5–7 day range is based on continuous 24/7 tracking with all sensors active.

Heart rate (via PPG optical sensor), heart rate variability (HRV), sleep stages (deep, light, REM), skin temperature, calories, steps, and exercise detection. The ring covers core biometrics; the bracelet adds SpO2 (blood oxygen); the necklace adds respiration rate. All data is local-first — it belongs to you.

Three main differences. First, no subscription — Oura charges $5.99/month ($72/year) to see your own health data. Over two years that's $493 total vs. $299 with Sensora. Second, design — Sensora is jewellery-first with 14+ finish options; Oura is tech-first in four finishes. Third, durability — Sensora is engineered for 3–5 years with a 3-year warranty and proactive free replacement at 18 months. Oura users on Reddit report average failure at 6–9 months.
