Hi-Jack
Hi-Jack

Your friends control your Lock Screen.

Send a friend a photo. They accept the challenge, and it becomes their Lock Screen for as long as they agreed to. Playful, friends-only, and over in a flash.

How it works

Three taps, total chaos 😈

No filters, no algorithms — just you and your friends.

1

Send a Hi-Jack

Take or pick a photo, choose a friend, and set how long the challenge lasts.

2

They accept 🔥

Your friend sees it land and decides whether to accept the challenge or chicken out 💀.

3

Lock Screen hi-jacked

Accepting hands off straight to Set Wallpaper, so the photo becomes their Lock Screen instantly.

See it in action

From "oh no" to Lock Screen 📸

The whole loop takes about ten seconds. Photos shown are placeholders — your friends will do worse.

Why people stick around

Built for friends, not followers

Every feature exists to make sending and receiving a Hi-Jack more fun — nothing else.

📇

Find friends instantly

See which of your contacts are already on Hi-Jack, or share your personal invite link and connect the moment someone joins.

Real Lock Screen hand-off

Accepting a Hi-Jack can hand off straight to Apple's Set Wallpaper — no screenshotting, no manual saving.

🛡️

Safety first

Friends-only by default. Block and report are built in from day one, and blocking is immediate and mutual.
