We need to talk about your nightstand. If you are searching for the "best iPhone sleep tracker," you are probably looking for an app that listens to your breathing or tracks your movement while your phone sits on your mattress.
As a trainer who cares deeply about recovery, I am going to give you some advice that might sound counterintuitive: The best way to track your sleep with your iPhone is to leave your iPhone in the kitchen.
Blue light, late-night notifications, and the temptation to "doomscroll" are the enemies of deep sleep. If your sleep tracker requires your phone to be right next to your head, it might be doing more harm than good.
That is why my top recommendation for iPhone users isn't an app you keep on your pillow, it is the Oura Ring.
The Oura Ring is a smart ring that syncs flawlessly with the Oura App on your iPhone. I received mine as an early Christmas gift last November, and it has completely changed my routine.
Here is why I consider it the ultimate iPhone companion for sleep:
Many iPhone apps that use the microphone to track sleep can be inaccurate. If your partner snores or a car drives by outside, the app might think you are awake. The Oura Ring uses sensors directly on your finger (where the pulse is strong) to give you lab-quality data.
If you are serious about fixing your sleep, get the device that lets you disconnect. Your body (and your iPhone battery) will thank you.
