Embedded piezoelectric 'trampolines' capture energy from your daily movement and store it as backup battery power.
Start with a tiny tadpole and watch your frog evolve through stages as you move. The more you walk, the more it grows!
Unlock augmented reality features, compete with friends, and complete challenges that make fitness feel like play.
You open your phone after a day of walking and see your tiny frog has transformed from a tadpole into a tree frog, unlocked new AR abilities, and generated enough stored energy to add 2 hours of battery life — all just from carrying your phone.
For health-conscious millennials who want fitness to feel like play, not work.
