Glyphrail.

One connected run, not one disposable board.

You get ten guesses to spend across three connected five-letter words. Clear one and some of its letters lock into place as anchors in the next, so the chain carries forward. It's word deduction without a clock, and it plays the same on iPhone and iPad.

A short run you can finish in a sitting — and no guilt on the days you skip it.

What's in the app.

• A daily relay, every day — with streaks for the consistent.
• Fifteen bundled practice drills — none of them touch your streak.
• A notebook of your last thirty runs — unlock the full archive once, for $4.99.
• Anchors that carry forward — clear a word and its locked letters seed the next.
• Offline by design — no accounts, quiet by default.
• Hardware-keyboard play on iPad — type your run without lifting a hand.

Color never works alone.

Every tile state carries a shape as well as a color, so meaning never depends on color alone — plus three colorblind-friendly palettes tuned for protanopia, deuteranopia, and tritanopia.

• Full VoiceOver labels on every tile, key, and control.
• Dynamic Type to the largest sizes, with the board reflowing to a single vertical column.
• Reduce Motion trades springs for quiet crossfades.
• Forty-four-point touch targets throughout.
