About
Walk, run or work out — every active calorie you burn becomes a tree. Plant your trees to turn the solar system green, one world at a time, from the Moon all the way to the Sun.
■ How it works
① Walk, run or work out — a device like Apple Watch records your active calories
② Every 1 kcal becomes one tree
③ Plant your trees and fill each world with forest
■ A forest that grows as you move
· Calorie Forest turns Active Energy from the Apple Health app into trees. Active Energy is recorded when you move while wearing a device like Apple Watch.
· Moon → Mercury → Venus → Earth → Mars → Jupiter → Saturn → Uranus → Neptune → Sun. Each world grows its own kind: trees, crystal sprouts, cloud mushrooms, cacti, balloon flowers, star candy, ice coral, snowmen and fire flowers.
· Fill a world and it beams with joy while your crew jumps around. Share your completion card with friends.
■ 30 cute friends
· Open a box with 300 trees to meet a new friend — from common friends to a 0.01% miracle. All odds are shown in the app.
· Boxes open only with trees you earned by moving. Trees can't be bought — it's fair for everyone.
· Up to five friends join your expedition and wander your planet.
■ No pressure
· No streaks, no penalties. Take a day off — your forest stays.
· Gentle music for every world plays quietly in the background.
■ Privacy
· Your health data never leaves this iPhone. No account needed.
· Your forest is saved only on this iPhone. If you switch devices or delete the app, it can't be restored.
* Steps aren't counted, and calories you enter manually in the Health app don't become trees. Up to 3,000 trees per day.
* Calorie Forest is not a medical app.
