Walk, and the world's trees grow.
With every step from your daily walks, you grow trees like the Baobab and the Dragon Blood Tree as bonsai — slowly, quietly.
Each tree you complete is saved in your catalog. Your own personal collection of the world's trees grows, one walk at a time.
Turn your step count into a quiet act of collecting.
