5 tech splurges that are 100% worth it (and on sale, thankfully)

A $350 smart ring (with a $70 annual subscription) isn't cheap. I know. But as someone who has tested every smart ring competitor on the option, I gotta give it to Oura. Its smart ring really is the best. 

Oura's sleep, stress, and exercise-tracking smart ring nails the big and the small stuff. It discreetly and accurately measures my sleep, and offers helpful insights each morning explaining how and why my sleep was great or poor. I've learned about what keeps me from falling asleep quickly, whether that's a heavy meal or a few alcoholic drinks before bed, because of Oura's helpful analysis and explanations.

It measures my stress throughout the day and compares that average stress level to my baseline -- it even shows me, through Cumulative Stress, my daily stress level's overall impact on my health. Oura's Symptom Radar has accurately detected illness within a day of me getting sick. 

The smart ring also has integrations across different apps and products, like Dexcom's Stelo, a continuous glucose monitor, or Natural Cycles, a hormone-free menstrual cycle tool. 

During Black Friday sales, the Oura Ring 4 Titanium is 30% off. That brings the starting price of $350 down to $250 -- not too shabby.
