The phone shaker is an automatic Steps Earning Device. It is recommended for those who want to increase the number of walks! Increase steps with apps such as Pokemon GO (Adventure Sync), Google Fit, and more.
It shakes automatically and you will earn 8,000 to 10,000 steps per hour easily! As you earn more than 30 km steps while sleeping (about 6 hours) while sleeping, securing of the candy and hatching of eggs become much fun.
