Which is better for sleep tracking?

Both focus on sleep. Oura has the more mature app and longer track record. Air reviewers often praise sleep tracking too, but some doubt the accuracy of its readings.

Is the Oura Ring 5 worth the extra money?

At $343.98 versus $129.99, you pay about $214 more. That buys a more polished app and brand support, not more sensors on paper.

Which ring is more comfortable to wear at night?

The Air is 2.4 g and 2.4 mm thick, which reviewers call light and comfortable during sleep. Oura does not publish those figures in this listing, so the Air has the clearer comfort case.

The Air lists 4 to 6 days of battery. Oura's figure is not given here. On durability, Air reviewers report breakage and replacements, so neither is clearly the tougher ring.

Do I need a subscription?

The Air needs no subscription for core tracking. Oura's advanced insights sit behind a paid membership.

Can I wear either in the pool or shower?

The Air is rated to 100 m. Oura's water resistance is not stated in this listing, so check Oura's spec before swimming with it.
