If you’ve seen ‘Lie to Me’, you’ll recall Cal Lightman saying we lie every 10 minutes in conversation. Well, today, I want to tell you about some entertaining lie-detector apps that can help spot lies or even prank your friends!
Now I know these apps aren’t as accurate as real polygraph tests, but they can still be fun ways to get a sense if someone is stretching the truth. Apps like SpyLie analyze eye movements and microexpressions using your phone’s camera, while Truth Detector monitors vocal pitch changes.
While not foolproof, a little lie detecting with these apps can spice up a night with friends, as long as you don’t take them too seriously or use them unethically. So give them a try for some laughs, but don’t judge someone’s honesty solely based on what these apps say!
Best Apps for Lie Detection
These popular lie detector apps use different methods – scanning fingers, and palms or reading faces – for fun laughs with friends and family. Some claim to detect lies by finger scan, others by palm scan, and some analyze facial expressions.
While not foolproof, playing with these diverse apps can spice up a night in, especially if someone claims something unbelievable like “I love grandma more than my girlfriend,” and it says “Truth!” Just remember to take any results lightly and only use them as willing participants for entertainment.
Note for Users: Lie detection is a science that requires experts who can either pick up lies on the basis of human emotions and responses or on the basis of psychoanalysis. Forensically, this science requires medical experts who administer certain narcotics that make you lose all inhibitions. These apps, however, are only for fun.
