An honest health-tracker comparison
Ray versus Circular Ring 2
Circular Ring 2 is still a pre-order rather than an ordinary retail purchase. Compare its current campaign claims with a screen-free tracker you can evaluate on price, upkeep and everyday wear.
The short answer
Choose Circular Ring 2 if you accept crowdfunding risk for an on-demand ECG ring. Choose Ray if your priority is a quiet, screen-free tracker that avoids both a charging ritual and a required subscription.
Campaign pricing and fulfillment estimates can change; this is not presented as a currently shipping retail product.
The useful differences
Side by side.
Specs are manufacturer claims and US pricing snapshots, not lab-test results. A blank promise is less useful than a clear tradeoff, so we keep this list deliberately practical.
| What changes | Chargerless Ray | Circular Ring 2 |
|---|---|---|
| Format | Screen-free wristband | Smart ring |
| Power | Light powered; no charging routine | Rechargeable; up to 7 days claimed |
| Screen | None | None |
| US price | $199 silver / $229 gold | About $299 campaign price / $349 list |
| Required subscription | None | No required core subscription; optional premium features planned |
| Core tracking | Sleep, heart rate, HRV, temperature, steps and light exposure | Sleep, activity, recovery, HR, HRV, temperature and on-demand ECG |
Choose by priority
Neither wins every category.
The best tracker is the one whose compromises fit your life—and that you will actually keep wearing.
Ray's case
No cable. No screen. No subscription.
Ray is a normal retail purchase with no charging dock or finger sizing step.
Circular Ring 2's case
Pick it for what Ray leaves out.
Circular Ring 2 promises ECG and a compact ring form, but remains a Kickstarter pre-order.
Research note. Competitor facts were checked against Circular Ring 2 Kickstarter FAQ on August 20, 2026. Prices, promotions, regional features and announced-product timelines can change. Ray details reflect the current Chargerless product page. Neither product is a substitute for medical care.
Wear your health. Not a charger.
Ray tracks the essentials in a 7-gram bracelet powered by light. Silver starts at $199. Gold starts at $229. No required subscription.
