Ever wondered if someone is telling the truth? With Truthr, you can now get real-time insights into truthfulness by leveraging the advanced biometric sensors on your Apple Watch. Truthr monitors key physiological indicators known to shift under stress or deception. These include heart rate, heart rate variability (HRV), skin conductivity, and blood oxygen levels — all collected seamlessly from your Apple Watch. Our algorithm interprets these micro-changes to estimate the likelihood that someone is lying during a conversation, test, or personal reflection. Whether you're testing yourself or having a conversation where honesty matters, Truthr helps you uncover hidden patterns beneath the surface. How It Works: Once connected to your Apple Watch, Truthr continuously collects biometric data in real time. When the app is in lie detection mode, it compares your baseline vitals with changes triggered by emotional or cognitive stress — known signs of deception. Using signal analysis and deception probability scoring, the app presents a clean and intuitive result: likely truthful or possibly deceptive. Key Features: • Continuous heart rate & HRV tracking • Real-time skin conductance monitoring • Blood oxygen level detection • Proprietary stress/deception algorithm • Seamless Apple Watch support • Session history & insights • Privacy-focused: Your data stays on your device Why Truthr? Most peoplanalysisw subtle physiological changes when they lie — but they’re nearly impossible to notice without advanced tools. Truthr brings lie detection science out of the lab and onto your wrist, giving you a powerful tool for personal awareness, playful challenges, or private testing. Premium features: - Unlimited analysis and tests Disclaimer: Truthr is designed for entertainment and personal insight. While grounded in real biometric science, it is not a substitute for professional or legal lie detection.
