TruthScan AI is an entertainment app that turns any iPhone into a party lie detector. It analyzes voice stress and 43 facial landmarks to detect micro-expressions and delivers a “truth or lie” verdict with a confidence score. Features question templates, video recording and sharing, and multi-person mode. Freemium model with subscriptions and coin packs. Live on the App Store with zero paid marketing so far; I built it solo and have no experience running ads, so all traction to date is organic.
