Quick answer
Who Knows You Best? is a how-well-do-you-know-me app for iPhone with private answers, guesses, match percentages, online play, and shareable result cards.
What the app does
One player answers questions about themselves. The other player guesses those answers. At the end, the app calculates a match percentage and shows what each person got right or wrong.
Why use an app instead of a list
A list gives you prompts. An app gives you hidden answers, anti-cheat flow, scoring, stats, online play, and a shareable result. That makes it easier to play more than once.
