Escape rooms, spy movies, treasure hunts — ciphers are everywhere. Cipher Academy teaches you to actually read them — fast.

Pick a cipher. Start with single letters. Build up to full words. Each one has its own progression, its own challenges, and its own way to test you.

What you'll train

Twelve ciphers and three presets, each with its own progression. Start with the four free ones and add more whenever you like.

Morse Code
Braille
Pigpen
A1Z26
Binary & ASCII
Polybius Square
ROT13 & Atbash
Semaphore & Flags
Bacon's Cipher

Built with respect

No ads. No subscriptions. No tracking. No internet required to play. One optional purchase unlocks everything — forever.

Cipher Academy runs entirely on your device, collects zero data, and will never send you a notification.

How it works

Every cipher follows a carefully designed learning path. Morse starts with symmetrical patterns for intuition, then shifts to recognition-based progression inspired by the Koch method. Braille pairs each base shape with its extended counterpart, building from simple one-dot patterns to complex combinations. Pigpen traces the geometry of its grid. A spaced repetition engine schedules your reviews so symbols stick in long-term memory.

Research-informed, transparently

Cipher Academy's learning paths draw on well-established ideas from cognitive science — spaced repetition, the Koch method, and recognition-based progression.

These principles are well-supported, but their specific implementation in Cipher Academy hasn't been validated through controlled studies — and we're upfront about that.
