Do [Not] Forget
Read full descriptionHide full description
DNF is a retro-styled memory game rendered on a glowing CRT phosphor screen. Each trial, a pattern of cells lights up on a 5x5 grid.Study it. Then recreate it from memory. Sounds simple — until the patterns grow larger and the display time shrinks.
Lattern
Read full descriptionHide full description
Lattern is a 60-second daily memory ritual. Calm, precise, and deliberately not brain training. Each day, a grid lights its cells one by one. After it rests, you light the same path back from memory. The sequence builds as you go: three for the day, a little longer each round. Get it, and your Lattice fills in, a quiet pattern of light that grows day by day. • One new Lattern every day, the same for everyone • A gentle build-up, a few tries, never a harsh fail • The Lattice: your streak, as a calendar of light • Apple Watch and home-screen widgets • No accounts, no noise, no pressure Lattern+ unlocks practice grids, 1,000 training levels, your full history, and removes ads. Quiet work. Same time tomorrow. Privacy policy: https://lattern.app/privacy Terms of use: https://lattern.app/terms
