Syde brings small adventures back into your life. Every morning you get one "Side Quest" — visit a museum, step into a shop you always walk past, just sit on a park bench. Not required, but the kind of small thing that makes a day a little richer. Take on the quest, then capture it as a short video in the app. Watch others who tried the same quest, and cheer each other on with comments and likes. Following people you admire turns into little discoveries — "you can live like that too." Who it's for • Anyone whose days feel like a loop of "work (or school) and home" • People who want to try things but lack the nudge to start • Anyone who wants to step back from the noise of social media and add more real-world time What makes Syde different from typical social apps • The goal isn't time spent in the app — it's the number of real things you actually do. • No infinite scroll designed to melt your time away. • No leaderboards ranking people by followers or likes, and no shaming the days you skip. It's okay to have an off day. How it works 1. Pick a quest from the one that arrives each morning 2. Film a short video in the app 3. Post it and cheer on others who took the same quest 4. Look forward to "what will tomorrow's quest be?" Do one thing today you'll be glad you did. —— Syde is open to everyone — sign up with just your email. Got an invite code from a friend?
