About this app

Curious if your friend is lying?

Hand them your phone and tap 'Start Scan' instant party. This prank lie‑detector app fires up laughs at parties, hangouts, and trips with multiple modes: fingerprint scanner, voice detector, and eye tracker (camera AR overlay).

Key Features ::

1. Fingerprint Mode (1P / 2P Battle): Hold a finger on the on‑screen scan pad to trigger pulse‑style animation and a result. In 2‑player mode, see who’s 'lying' to the question.
2. Voice Detector: Ask a question, capture (or trigger) the reply, then get a playful Truth / Lie reveal.
3. Eye Detector: Face detection + glasses‑style HUD overlay + scan animation for a 'truth analysis' vibe.
4. Simple Home Screen: Quick‑launch buttons for Fingerprint, 2 Player, Voice Detector, and Eye Detector modes.

How to Play ::

Launch the app and choose a mode.

Ask a question: 'Did you really work late yesterday?'

The player responds: place a finger, speak, or look at the camera.

Watch the scan animation—automatic Lie / Truth result → everyone cracks up.

2‑Player Mode: Both place fingers and play a mini game to see who looks more suspicious.
