A smart ring that doesn't charge you every month

The Oura Ring 4 costs $299 upfront plus $5.99/month. That's $371 in the first year alone. Adola gives you six sensors, sleep staging, and snore detection for $79.99 total. No subscription. No hidden fees. No paywall on your own health data.

Why do smart rings charge subscriptions?

Oura introduced its subscription in 2022 to fund ongoing algorithm development and server costs. The problem: your biometric data is collected by sensors you already paid for, processed on your phone, and stored on their servers. Adola processes everything on-device and gives you full access to your raw data from day one.
