Earlier this week Asus announced its VivoWatch, the first Asus wearable designed for fitness tracking.
It has built-in heart-rate monitoring, sleep tracking, and a Happiness Index that shows a person’s overall mood.
It uses a numeric score, based on the wearer’s activity level and sleep quality to shown a summary of how healthy the wearer’s lifestyle is.
A low score suggest the wearer should adjust their exercise and sleep habits, while a normal or high score provides motivation to maintain their healthy lifestyle.
Asus claims the £119.99 VivoWatch has a 10-day battery life, and the watch case is IP67 water-resistant. It goes on sale in May.
