Travel the whole history of life as one living, branching river of light. Everbranch turns 13.8 billion years into a place you can explore in 3D. Start at the Big Bang and drift downstream through the first stars, the primordial ocean, the first cells, the Cambrian explosion, the age of dinosaurs, and the rise of us — then follow the side-rivers: plants, fungi, arthropods, molluscs, dinosaurs-to-birds, the great mammals, the unseen world of microbes, cartilaginous sharks, and amphibians between two worlds. • A living 3-D cosmos — pan, pinch and tap a glowing tree of 186 milestones across 53 lineages. • Journey mode: the tree unfolds one milestone at a time, so you always know where you are and what comes next. Switch to Explore whenever you want to roam the whole tree freely. • Find a common ancestor — pick any two living branches, like you and mushrooms, and watch the path light up to the ancestor they share. • Real, public-domain imagery (NASA, Hubble, classic natural-history plates) on the cosmic spine and many organisms. • A detail card for every milestone: what happened, why it matters, key stats, and related milestones to jump to. • The Logbook — a collectable album of every specimen you have discovered, with full search. • An era index with a timeline scrubber, bookmarks, and "continue where you left off". • A gentle quiz and "did you know?" facts to test what you have learned. • Optional ambient soundscape and narration, in all 8 supported languages. • A "milestone of the day" home-screen widget and daily reminder. • Built for accessibility: VoiceOver, Dynamic Type, Reduce Motion and Reduce Transparency. • A living, growing cosmos: new milestones, lineages and imagery arrive over time, and content already on your device keeps working offline. • No account. No ads. No third-party tracking. EVERBRANCH PREMIUM An optional subscription that unlocks: • The full Guided Tour — a cinematic, narrated show through all 17 chapters (the first 3 are free for everyone). • Watch It Grow — a time-lapse of the entire tree growing from the Big Bang to today. • AR Mode — place the tree of life on a table and walk around it.
