Casti.

With friends worth your time. That's the cap.

A social app just for the friends you invite.

Casti connects you only with friends you already know. No follow buttons. No endless feed. No anonymous likes. Just your close friends, kept small on purpose. That's Casti.

THE IDEA

Most social apps gave us thousands of "friends" we've never talked to. Casti goes the other way. It fills up with the people who are actually in your life — not an algorithm.

WHAT'S DIFFERENT

• Only people you know become friends. You connect when you both already know each other. Nothing is matched at random. Your list stays yours. • 15 friends by default. Save your relationship energy — time worth spending, with the people who matter most. • Diaries only you can see. They're encrypted — visible to you and the friends you invite. • Your own space. Share photos, diaries, and more. Only your closest friends can drop by.

WHAT YOU CAN DO

• Diary — Journal entries encrypted right on your device. Share with chosen friends, or keep them to yourself. • Photo Gallery — Albums where you decide who can view, comment, or add. • Chat — Talk 1:1 with your friends. Messages are end-to-end encrypted. • Guestbook — Leave a note on a friend's space. Like a digital visitor book. • Daily Pick — See what the people close to you are sharing. • Letter Box — Get updates from friends and their reactions. • My Places — Save places that matter and share them with friends.

SAFE TO USE

• 14+ only. Checked at sign-up. • You decide what to share, and who with. • Block and report on every person and post. • Encrypted in transit and at rest. • Your data is yours. Export or delete it anytime in settings.
