DayFit — Daily Calendar Puzzle

8 wooden pieces, 2 minutes

$0.99 · Designed for iPad. Not verified for macOS.

No ads. No in-app purchases. No account. Works fully offline, even on a plane. Every past date stays open to replay — other calendar puzzles charge extra for that. 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.
