About
Think you don't flinch? Prove it.
FLINCH is the ultimate jumpscare reaction challenge. Play a simple focus game while a scare builds in the background. At a random moment — BOOM — a full-screen scare fires with audio, visuals, and haptics. Your phone's camera and sensors capture every micro-reaction. Did you flinch? The app knows.
HOW IT WORKS
1. Tap the dot — a simple focus task keeps your eyes on the screen
2. Stay calm — tension builds with ambient audio and a rising heartbeat
3. Survive the scare — a randomized jumpscare fires when you least expect it
4. Get your score — scored 0-100 based on your physical reaction
5. Share the clip — an auto-generated video of your reaction with your score burned in
YOUR FLINCH SCORE
Every scare is measured using your device's accelerometer and front camera. The app detects how much you moved, flinched, or jumped. Your score is calculated in real-time:
- 90-100: Statue. You didn't move a muscle.
- 70-89: Steely. Barely a twitch.
- 40-69: Human. Normal reaction, no shame.
- 20-39: Jumpy. You definitely flinched.
- 0-19: Launched. Phone nearly hit the ceiling.
SHAREABLE REACTION CLIPS
FLINCH auto-generates a short video clip of your reaction moment — your face camera footage with the scare overlaid, your score animated in, and a dare card for your friends. One tap to save or share. Built for TikTok, Reels, and Stories.
MULTIPLE DIFFICULTY LEVELS
- Rookie: Smaller scares, more time, easier targets
- Standard: The real deal
- Nightmare: Maximum scare intensity, faster targets, shorter fuse
