AI Lie Detector Party App

Ship an entertainment lie-detector app using voice stress and facial landmarks; monetize with subs and coins.

In plain English

Friends at a gathering can try a party lie detector that is labeled as entertainment only, and it is not a real police or court tool. It listens for strain in a voice, watches points on a face, and shows how sure it feels. People pay a subscription or buy packs of coins because they want a silly group game. The AI does almost all of the voice and face reading, and the phone store handles the purchases. The person running the app still writes the safety labels, posts party clips, and steps in if people misuse it.
