ZaZa / an Application for Sleep


Zaza is an application that allows you to get a reward from your actual sleeping hours. The rewarded points that you can receive from an application could be exchanged into a tangible product that helps you to sleep.

Our business model is a win-win. Companies that make sleep-related products can advertise in ZaZa. Users can get free items by sleeping on time. We always watch the screen on our smartphones all day long. Even in bedtime. ​People who lack sleep feel tired easily and have difficulty concentrating during the day.

That's why we think of Zaza. A simple but ingenious idea Sleep on time and get the reward for good sleep.
