I was a sleep tracker skeptic until I got my Withings Sleep Analyzer and now I check my metrics every morning. For a long time my sleep score has hovered around the low-70s, but recently I noticed my sleep score tracking upwards. The other day, I finally cracked 90. And it's all thanks to the 7:1 sleep method.
This simple rule, backed by a huge new study, prioritizes consistency over hacks and it's given my sleep the boost it needs. The best sleep trackers take in a range of metrics before giving your final score and with the 7:1 sleep rule, I'm pleasing all those data points.
