LieScan: Lie Detector

LieScan — The Prank Lie Detector

Think your friends can fool the scanner? Ask a question, choose a scan, and reveal the verdict.

LieScan is a playful simulated lie detector made for entertainment, parties, jokes, and pranks. It does not perform real lie detection, biometric analysis, AI analysis, or scientific measurements. Every result is generated locally by the app's simulation engine.

SCAN YOUR WAY

Choose from multiple fun scan modes:

• Finger Scan

Watch a futuristic radar sweep with biometric-style animations and scanning effects before the verdict is revealed.

• Voice Test

Hold to run a simulated voice test with an animated waveform and dramatic scan effects. No microphone recording is required for the simulation.

• Face Scan

Use the camera for a futuristic scanning experience with a HUD-style interface and animated scanning phases. The scan is simulated.

• Party Mode

Play with multiple people in a hotseat-style party game. Take turns answering questions, reveal verdicts, earn points, and see who ends up on top.

150+ QUESTIONS

Choose from more than 150 built-in questions across categories including:

• Friends

• Couples

• Family

• Party

• School

• Awkward

• Funny

• Kids

• Custom

You can also create your own questions directly in the app.

RANDOM QUESTIONS

Can't decide what to ask? Use random mode and let LieScan choose a question for you.

MAGIC VERDICT

Want to control the prank?

Choose your verdict mode:

• Auto — Generates a simulated result based on the question

• Always Truth — Forces a TRUTH result

• Always Lie — Forces a LIE result

LieScan also includes hidden touch controls that let the prankster secretly influence the result during a scan.

DRAMATIC RESULTS

Each scan mode has its own themed verdict messages and animations designed to make the reveal feel more convincing and entertaining.

CONSISTENT PRANK RESULTS

Questions use a local question-based result system so the same question can tend toward the same simulated verdict when repeated, helping the prank feel more believable.

Results include confidence percentages designed purely for entertainment.

DARK & LIGHT THEMES

Choose between:

• Futuristic dark mode with neon-inspired visuals

• Clean light mode with high-contrast UI

SOUNDS & HAPTICS

Enjoy scan effects, button sounds, reveal audio, countdown effects, and haptic feedback throughout the experience.

IMPORTANT

LieScan is an entertainment simulation and prank app.

It is not a real lie detector and cannot determine whether somebody is telling the truth. Its scans, confidence values, biometric-style messages, and verdicts are simulated and should not be used to make real decisions about people.

Use LieScan for laughs, games, parties, and harmless pranks.
