DayFit — Daily Calendar Puzzle

DayFit is a calendar you rebuild every day.

Eight wooden pieces. One calendar. The shape and the pieces never change — only the date does. Cover every square except today's month and day, and the day is yours. About two minutes.

WHAT MAKES IT DIFFERENT

• All 372 month–day combinations are solver-verified. There is no date where the puzzle can't be solved.
• Hints that keep your work — three a day. DayFit finishes the board around what you've already placed instead of wiping it.
• Check, don't spoil. Ask which pieces are wrong; the app marks them and leaves the rest alone.
• No streak shaming. Miss a day and your total stays. Come back whenever.
• Offline by design. Progress, streaks and settings live on your device.

FEATURES

• Daily puzzle, the same for everyone, everywhere
• Drag to place, tap to rotate, hold to flip
• Undo, redo, and a board that survives closing the app
• Calendar archive — revisit any past day
• Stats that stay kind: current streak, longest streak, average time, difficulty mix
• Twelve languages, light and dark wood themes
• Wooden sound effects on every placement, plus a looping tune you can switch off
• Runs on iPhone, iPad and iPhone Duo — the board rescales when you unfold it

ONE PRICE, EVERYTHING IN

DayFit is a paid app: $2.99 once. No subscription, no ads, no coins, no energy, nothing else to buy. Everything — the full archive, three hints a day, every theme, all stats — is included from the first launch.

A small note: this is a puzzle about a calendar, not a calendar app. It won't remind you about meetings. It will, however, make the date mean something.
