About
Curiosity killed the cat. We just film it.
Don't Open turns your phone into the world's most tempting trap. Leave a "do not open" message on screen, hand your phone to a friend, and walk away. The second they snoop, you catch their reaction on camera. Photo or video. Busted, forever.
HOW IT WORKS
1. Pick what pops up when they open it
2. Add a reveal: a photo, or huge words in Big Text
3. Arm the trap and hand it over
That's it. Three taps from "hmm" to "GOTCHA."
THE BAIT
Your phone shows a locked-looking screen with bait like "Don't open this." or "You're in this one", plus a hint designed to break their willpower: "Something in here is about you." Nobody can resist. Nobody.
THE CATCH
The moment they open it, the reveal hits them, and Don't Open captures their face:
- Reaction photo: one perfect snap of pure guilt
- Reaction video: 5, 10 or 15 seconds of them realising what they've done, with sound
- The timer: see exactly how long they held out before curiosity won
THE REVEAL
- Use a photo from your library, or take one on the spot
- Big Text: skip the photo and hit them with HUGE words. Full-screen colour and a little shake for extra drama
- Or keep it simple with just the message
SHARE THE EVIDENCE
Turn every catch into a story-ready card or video (1080x1920), made for Instagram, TikTok and anywhere else your friend can be publicly humbled. Includes how long they lasted, because that's half the fun.
EVERY CATCH, SAVED
All your catches live in one place with their reaction photos and videos, so you can relive the moment whenever you need a laugh.
MADE FOR IPHONE AND IPHONE DUO
On iPhone, they swipe to open. On iPhone Duo, fold it shut to arm it and the trap waits on the cover screen. The moment they unfold it: caught. The reveal and their reaction sit on either side of the fold.
MAKE IT YOURS
Dark or light mode and six loud colours: Lime, Hot Pink, Electric, Ultraviolet, Sunset and Aqua.
PRIVATE BY DESIGN
No accounts. No servers. Your traps, photos and reaction videos stay on your phone unless you choose to share them.
PLAY FAIR
Don't Open is for harmless fun between friends. When the camera turns on, the person holding your phone sees a clear "Recording" or "Camera on" badge, so the joke stays friendly. Please only share reactions with permission.
Go on. Hand it over. What's the worst that could happen?

What's New in Don't Open
1.1
October 16, 2026
Burst mode. Catch their reaction in a burst of photos instead of a single shot or a video. Pick 5, 10 or 15 seconds and it plays back as a flipbook of every face they pulled. Share it as a story-ready video. Notification bait. Leave your phone lying around and let a notification do the work. Set it to pop up after 10 seconds, a minute, 10 minutes or an hour, write whatever it says, and walk away. When they tap it, the trap is waiting. Preview your trap. See exactly what they’ll see before you arm it: the cover, the reveal and the reaction capture. Nothing is saved, so you can tweak the bait and try again as often as you like. Plus a clearer setup screen and small fixes throughout.
