Lie Detector: Prank & Play

Lie Detector: Prank & Play brings a pretend fingerprint scanner and party games to your next get-together. Ask a question, hold a finger on the screen, and share the playful result with your friends.

Fingerprint pranks and funny results

Watch the pretend scan progress, reveal your result, then share the result card or start another round. Explore 180 result variations across the lie and mood modes, with playful titles and lines to keep the conversation going.

Truth or dare

Switch between questions and dares, or bring the daily challenge into your game. Choose Truth for a question or Dare for a challenge your friends can act out.

Friends sessions on one phone

Set up a local session for 2 to 8 players. Add names and take turns choosing questions or fingerprint rounds. Share the session recap with your group.

Playful mood rounds

Watch an optional rewarded video to open mood rounds for the current app session. Get lighthearted mood results and switch between lie and mood modes after access is granted.

Sounds for your next prank

Choose sounds such as applause, laughter and a siren. Use instant playback, a timer or motion activation to match the timing of your prank.

Scanner looks and saved rounds

Choose cyan, blue or violet scanner looks, and use result steering options to plan your prank. Revisit the round history saved on your device and share your favorite results.

The app supports Arabic and English. Change the language directly from the home screen.

Ads and feature access

The app contains ads. Some extras require in-app coins or a rewarded video, depending on the feature. Rewarded video access to mood rounds lasts for the current app session.

For entertainment and pranks only

All lie and mood results are entertainment simulations. They do not measure truthfulness, real emotions or vital signs.
