Lie Detector Finger Scan

Settle the moment with a playful truth test and skip awkward guessing. Run a finger scan, get a dramatic lie detector verdict, and turn any hangout into a quick party game.

Lie Detector Finger Scan helps friends run a simulated lie detector scan for laughs, party prompts, and shareable results.

Everything happens on this device, with no account needed and no real lie detection claims. The app is built for entertainment, keeps a clear “For entertainment only” label on results, and gives you quick ways to start a scan, stop it, replay past results, or jump into party games when you want more than a simple finger scan.

- Run a Fingerprint scan with a large touch stage, animated scan line, progress bar, and clear Start Scan or Stop control.
- Switch result mode between Random and Preset when you want a surprise verdict or want to pin TRUE or LIE for a repeated demo.
- Turn on MAYBE for an inconclusive result and add more variety to each truth detector moment.
- Watch the verdict reel spin into TRUE, LIE, or MAYBE for a playful reveal, with a simulated stress meter shown beside the polygraph-style gauge.
- Save recent lie detector results with time and simulated stress, review summary counts, or clear history in one tap.
- Add your own question before a scan or use the random question generator when nobody knows what to ask.
- Use Shake-to-Scan for a faster party flow, and keep a Truth Streak going when the same result lands more than once.
- Jump into Party Games with decks like Truth or Dare, Would You Rather, Two Truths One Lie, Never Have I Ever, Hot Seat, Couples Quiz, Friend Confessions, and Icebreakers.
- Save favorite party cards, filter by category, share a party card image, or test reflexes in Reaction Time with personal-best tracking.
- Check Insights to see your TRUE, LIE, and MAYBE split, daily activity, scan mode usage, and party deck activity over time.
- Share a result card image with a simulated entertainment badge so friends see the joke right away.

- Break the ice at a party with Duo mode, then pass the phone back and forth for turn-based scans.
- Add a random question before a Fingerprint scan when the group wants a quick truth or dare style prompt.
- Use the History list after game night to replay funny verdicts and compare simulated stress scores.
- Open the daily question from the Home Screen widget when you want a fresh prompt without thinking.
- Start a quick reaction challenge between rounds of Would You Rather or Never Have I Ever.
