Silent alarm clock and sleep sensor for iPhone/iPad. Designed with Harvard sleep expert and pro sports sleep coach. LARK wakes you silently and gently- you’ll even snooze less. The LARK wristband (lovingly known as wrist pajamas) uses an actigraphy microsensor to detect your unique sleeping patterns. No syncing, it automatically shows up on your phone.
Jawbone UP is the app-powered wrist band that inspires you to feel better and live heathier ... UP tracks every move you make — it even reminds you to move more.
