Read full description

Timeline is a different kind of social network. Instead of asking what you're thinking, Timeline asks what you did. Every day you add Moments — went hiking, had lunch with Mom, finished a book, took the kids swimming. Some are ordinary. Some are milestones. All of them add up to the record of your life. BUILT AROUND YOUR DAY • One line is enough — type what you did and post it • Add photos, a place, who you were with, how it felt • Mark the big ones as milestones PRIVATE BY DEFAULT IF YOU WANT IT • Every Moment is public, friends-only, or completely private • Private Moments never appear in feeds, search, discovery or on the web • Privacy is enforced on our servers, not just hidden in the app YOUR WHOLE LIFE, NOT JUST TODAY • Add Moments from any point in your past • Don't remember the exact day? Use "Summer 2018", "Around 2015", or "Around age 16" • Fill in years at once by importing photos you already have • Scroll back through your life on one timeline, year by year • Search everything you've ever recorded A SOCIAL NETWORK ABOUT REAL LIFE • See what people are actually doing, not just their highlights • "I Did This Too" connects you through shared experiences instead of reposts • Challenges, streaks, Life Stats, On This Day and recaps you can share You control who sees what, you can report or block anyone, and you can delete your account and everything in it at any time. Timeline is free.
