Questions and answers

Which is better for sleep tracking?
Both are strong. The Oura Ring 4 is built around sleep and is comfortable enough to wear overnight. The Venu 4 adds sleep score, stages, naps, HRV status and skin temperature, but the watch is bulkier on the wrist at night.
Do I need a phone with the Oura Ring 4 for runs?
Yes. The ring has no GPS, so distance and route come from your phone. The Venu 4 has built-in GPS with Galileo, GLONASS and BeiDou.
Is the Garmin Venu 4 worth the extra money?
Only if you will use the screen, GPS and training plans. At $450.00 at eBay as of November 5, 2026 versus $188.97 for the ring, you are paying about $261 for a watch you train with.
Which lasts longer on a charge?
The Venu 4, at up to 12 days versus up to 7 days for the Oura Ring 4.
Can I swim with either?
The Oura Ring 4 is listed as water resistant. The Venu 4 is water resistant but not waterproof, so avoid swimming and diving with it.
Which works with iPhone?
Both list Android and iOS support. Note the Oura Ring 4 is reported to share data only with Apple Health, not other third-party apps.
