About

TreeGo

Features
Read full description

TreeGo is a real-world tree exploration app. This is not about collecting characters on a screen. It is about getting to know real trees. ● One Tree, One Specimen Card Every tree you record gets its own specimen card. Come back on another day and record the same tree again. Each revisit adds another of your photos to the card. New buds in spring, shade in summer, falling leaves in autumn: the same tree slowly becomes an old friend. ● Tree Handshakes The first time you Echo a tree someone else discovered, you shake hands under that tree. You each appear on the back of the other's card, together with your photo of the tree. ● Growth Rings & Weekly Stamps Every record adds a growth ring to the tree, from Baby Tree all the way to Sacred Tree. Record a tree in any week and that week gets a stamp. ● Two Ways to Explore • Mission Mode New featured species every two weeks. Find and check in the designated tree species. Be the first to discover a mission species and become a Pioneer, earning double Echo points. • Free Exploration (Seed Mode) Walk your own path. Check in trees you recognize. ● Achievements TreeGo records more than locations: • First check-in in the rain • First check-in below 0°C • 100 km between two check-ins • Weather and distance-based milestones ● Plant Oracle (TreeGo Pro) Subscribers can unlock Plant Oracle for mission species. Previously collected trees can also trigger new readings. Each tree offers a different reflection. Sometimes unexpected. Sometimes precisely what you needed. ● Why trees? Trees don’t move. We do. Today, which tree will you meet? Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
