If you’re monitoring your fertility and trying-to-conceive, then this ring is for you. It helps predict fertile windows, tracks your body basal temperature, and can determine ovulation days. It also tracks and analyzes your sleep patterns during each phase of your menstrual cycle, which can be super wonky depending on what stage you’re in.

Cons
- Delivery could be up to 20 days depending on where you live
This smart ring is designed to wear only at night (which is helpful since, TBH, she’s more function than form), but don’t worry—the Go2sleep is super lightweight so it won’t disrupt your much-needed snooze time. While you’re knocked, the device is tracking and monitoring your blood oxygen, heart rate, sleep stages, and so much more. Then, when you wake up and take it off, it starts syncing and then will provide a daily, weekly, and monthly report on all the data it’s collected. Starting off a morning with coffee and analyzing my sleep behaviors? Don’t mind if I do!
| Battery life | Up to two nights |
