About this app

"Is the 5-second rule real?" "Do fans really cause death overnight?" "Must you drink 8 glasses of water a day?"

We've all heard these myths and old wives' tales. But are they actually real?

'Is it real?' never tells you a myth is simply true or false. Instead, it neutrally summarizes what real research has found, and shows you links to genuine sources like NIH, NHS, NASA, universities, and Snopes. The app doesn't decide for you. You read the evidence and make up your own mind.

117 myths inside, for example
- Health & food: 8 glasses of water, coffee as a diuretic, the 5-second rule
- Body & life: fan death, swallowed gum lasting 7 years, the 10 percent brain myth
- Animals: goldfish 3-second memory, blind bats, dirty pigeons
- Space & nature: the Great Wall seen from space, lightning never striking twice
- Safety: pumping the brakes on ice, AWD being safe on ice, black ice needing snow

Every myth shows an evidence strength at a glance (well supported / contested / little evidence / essentially a myth), plus a research summary and links to the originals. Perfect if you love science facts, trivia, and fact checking common misconceptions. Works fully offline and supports both English and Korean. Take on one myth a day and tell fact from fiction.

Note: For information and entertainment only, not medical advice. Consult a professional for health or medical decisions.
