Smart rings, compared on what actually costs you money
Four flagship rings. The sticker price is the smallest part of the decision - subscriptions, phone compatibility and battery life decide whether you keep wearing it.

The three real differences
What separates these rings
Subscription, or not
This is the biggest long-run cost split in the category. One of these four requires a paid membership for its core experience; the other three do not.
Which phone you already own
One ring rules out iPhone entirely. Others set minimum OS versions. Buying the wrong ring for your handset is an expensive mistake with no software fix.
How often you charge it
Battery range spans roughly 6 to 15 days across this group. A ring you have to charge twice a week is a ring you stop wearing.
