Yen near multi-year lows means your dollars go further in Japan this summer. Convert prices instantly, tally shopping totals, and practice thinking in yen before you fly.
Yen Sense is a fast, private pocket converter for Japan travel. Enter a yen amount, see the USD estimate instantly, add up shopping totals, refresh the live rate when you have a connection, and keep a manual or cached rate for offline use.
The built-in Practice mode helps you learn common Japan travel prices before you are standing at a vending machine, train gate, cafe, or shop.
Yen Sense Pro is a one-time unlock for travelers who want more depth: the full Practice deck with history, extra home currencies, and the Home/Lock Screen rate widget. The free core converter stays useful forever, with no ads, no tracking, and no subscription.

Practice mode, redesigned. Practice is now a fast full-screen game: rounds of 5 real Japan prices, a custom keypad (no more system keyboard), an accuracy meter that shows how close your guess was, and a round summary with your streaks. Same spaced-repetition smarts underneath — it quizzes you on the prices you're shakiest on.
