Fitbit Flex is currently retailing for S$129. It was launched in Singapore last year on the 29th May 2013.
Fitbit Flex is a wireless activity tracker that tracks steps, distance, and calories burned. It is also able to track your sleep quality (how long/well you sleep, how many times you wake up). It also has a silent wake alarm that gently vibrates to wake you at your desired time.
