Oura Ring 4 Beats Apple Watch 10 for Sleep Tracking as Battery Lasts 144 Hours

Tom's Guide recommended the $349 Oura Ring 4 over the Apple Watch 10 for buyers focused mainly on sleep, citing deeper overnight metrics, more personalized insights and better comfort in bed.
The ring tracks HRV, oxygen saturation, sleep latency and chronotype, while its app adds AI-driven advice; Apple’s built-in tools cover core sleep stages and scores but offer less detailed guidance.
Battery life widened the gap: Oura lasts up to 144 hours, versus 18 hours for the watch, making multi-night sleep tracking easier without frequent charging.
Apple still held advantages for broader use, including workout tracking, calls and notifications, plus an FDA-cleared sleep apnea detection feature that Oura lacks.
On price, Oura starts at $349 but requires a $5.99 monthly subscription, while the discontinued Apple Watch 10 can be found from about $215 refurbished or $354.30 on sale.
