Spot the lie. Train your brain. — Support & FAQ
Questions, bugs, or feedback? We'd love to hear from you and usually reply within a couple of days.
How do I play?
Each round shows five surprising facts. Four are true and exactly one is a lie. Tap the fact you think is false, then submit to see if you spotted it.
Where do the facts come from?
A fresh set of rounds is generated every day across categories like Science, History, Pop Culture, Sports, and more. If you're offline, the app falls back to a built-in set so you can always play.
What is a streak?
Play and answer correctly on consecutive days to build your streak. Miss a day and it resets. Your stats are stored privately on your device.
How do free plays work, and what is Pro?
Everyone gets a few free plays each day. Going Pro unlocks unlimited plays and the explanation for why each lie is false. It's a one-time in-app purchase.
I bought Pro on another device — how do I get it back?
Open Settings inside the app and tap Restore Purchases. As long as you're signed in to the same Apple ID, your Pro access will be restored.
What data does One Lie collect?
None that identifies you. There's no account or login. Your game stats live only on your device, and no personal data is collected or shared.
