Hi Guys,
What are the most recommended products for monitoring heart rate and sleep?
Beddit is probably the most widely known, purpose built sensors for sleep and heart rate. Be careful, the reviews for their Android app are terrible and have dissuaded me from picking one up. iOS compatibility seems good though.
Seems it is not yet available for sale - and I got a Samsung S3 so I’ll need an android device. Any other suggestions? 
Chest strap models: A wireless sensor on a chest strap detects your pulse electronically and sends that data to a wristwatch-style receiver, which displays your heart rate.
Basic models time your workout and give you continuous, average, high and low heart rate data. Many advanced models submit a coded signal to prevent other HRMs from interfering with your data.
