As a tech reviewer and writer, I test out lots of technology each week. While I can normally designate a product's use for a specific person or group, it's much harder to recommend the product to most people, a qualifier I use only in rare instances.
The Oura Ring 4, however, is one of those products I have recommended to anybody who asks me about my favorite technology. It's so good I have even told my own mother, one of the more critical people I know, to buy one for herself.

The main reasons boil down to its sleep tracking, wealth of data insights, and illustration, and general tendency to alert you of possible illness or strain, thanks to its intelligent predictive algorithm. I have made several positive changes to my daily routine and have become aware of my less healthy habits thanks to the Oura Ring.
Despite its small size, it comes with a big price -- $350 plus the additional annual $70 subscription for full access to its data capture. Thankfully, however, the Oura Ring 4 Titanium is seeing one of its largest sales in the lead-up to and during Black Friday. Oura is offering a 30% discount on its Titanium Oura Ring this holiday season. If you've been eyeing one for a while, now is the time to buy. If you're unsure whether to get one now, keep reading to find out if it's right for you.

It also tracks daytime stress, specifically how often a person's heart rate exceeds a relaxed state, and cumulative stress, which measures the long-term impact of that aforementioned daytime stress on a person's ability to recover.

Each morning, I receive a sleep and readiness score that summarizes when my resting heart rate lowered, how many hours of sleep I received, and how restored or unprepared I am to take on my day. I wear the ring almost 24/7, so it's monitoring my daily exercise, my heart rate fluctuations as I work or rest, and my sleep quality.
