Sleep as Android 
"an alarm clock and sleep cycle tracker, wakes you gently in optimal moment for pleasant mornings"

Common alarm clocks ignore your sleep cycles, they wake you on schedule no matter your are currently in your deep sleep. Waking up from deep sleep is unpleasant, it makes you tired and it may negatively affect your productivity during the whole day. 

Sleep as Android is different. It tracks your sleep to find the optimal moment for your wake up. Waking up in light sleep is natural, gentle and it may only be compared to the experience of waking up without any alarm clock. 
Sleep as Android is available on the Pebble appstore

Nature sound Lullabies  for pleasant fall asleep. Rather that fixed recordings our lullabies are real-time synthesized, this means each playback will never be the same as the playback before. We use various techniques to make each lullaby a unique experience. Our lullabies take you into different pleasant environments to free your mind from stress and thoughts on everyday tasks. You may experience diving in the ocean with a whales surround you, lay on grass beside a mountain stream surrounded by various kinds of birds, listening to frogs or crickets, walk on a sandy beach near a port or just sit safe at home near your glowing fireplace listening to the wood crackling...

Snoring detection and anti-snoring — we have greatly improved our snoring detection. Over a long period of time we have gathered some 300 example recordings of snoring and those have been used to teach the algorithm. Snores are marked in your sleep graph, the overall snoring duration is accounted and you may be stopped from snoring by vibration or tongue click sounds.
