Six sensors. Under $80.

Smart rings from Oura, Samsung, and Ultrahuman cost $250-$450. Adola packs the same core sensors -- plus a microphone and NFC that they lack -- into a titanium ring for $79.99 with no subscription.

Price comparison: smart rings in 2026

What makes a cheap smart ring actually good?

Most budget smart rings under $50 on Amazon use generic sensors, lack sleep staging, and ship with apps that barely function. Adola uses the same medical-grade sensor components as rings costing 3-5x more:

• --MAX30102 PPG for heart rate and SpO2 (same sensor class as clinical pulse oximeters)
• --TMP117 temperature sensor with ±0.1°C accuracy (medical-grade)
• --LSM6DSOX 6-axis IMU with on-chip machine learning core
• --IM72D128 PDM microphone for snore detection (unique to Adola)
• --nRF52833 BLE 5.1 SoC with NFC (not found in any ring at this price)
• --Grade 5 titanium shell, same alloy used in Oura and surgical implants

How is Adola so affordable?

No retail markup. No subscription revenue model to subsidize hardware losses. No marketing budget baked into the price. Adola sells direct to customers and makes margin on the hardware itself, not on locking your data behind a paywall.
