A calm daily memory grid game. Each day, the grid lights its cells in sequence: watch the order, then light it back from memory. Three quiet rounds, and a streak that's yours to keep.
Free on the App Store & Google Play.
The daily grid, the growing sequence, and the Lattice your days light up.






No timers, no pressure, no notifications begging you back. Just a small daily moment of focus.
The Lattern lights one cell at a time. Notice the path, position and timing.
Repeat the sequence from memory. A calm pulse tells you how you did.
Each solved day adds a cell to your lattice. Come back tomorrow, or don't, it'll keep.
Every day you play lights one more cell in The Lattice. Over weeks, a quiet pattern builds, a record of showing up, not a scoreboard.
No flames. No badges. No "don't lose your streak."
Memory grids, sequence spans, Simon nostalgia, and honest answers about training.
Watch the path, light it back: why the format endures and how Lattern plays it.
