Independent testing
How much independent testing exists for each smart ring
Of the 6 smart rings we track, 6 have been physically measured by at least one independent lab and 2 by three or more. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Samsung Galaxy Ring | 4 | 2 | 4 |
| Oura Ring 4 | 3 | 5 | 4 |
| Ultrahuman Ring AIR | 2 | 2 | 2 |
| Oura Ring 3 Horizon | 1 | 1 | 2 |
| RingConn Gen 2 | 1 | 1 | 2 |
| RingConn Gen 2 Air | 1 | 1 | 2 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Smart Rings buying guide and the reviewers we cite.
