EchoTrace

Practice short-term sequence recall in a calm offline game built around four clear symbols and simple local progress tracking.

Start with a guided round that uses only two symbols, then unlock the full set of practice levels. Choose classic forward recall, reverse recall, or missing-gap recall, and use the daily challenge when you want a stable local route for the current date.

Each session moves through prepare, demo, input, error, advance, and finish states. The demo phase shows the pattern first, input accepts taps in order, and the one-time replay option is available before you answer. Mistakes are counted locally, and the round replays so the next attempt is easier to learn from.

The app keeps local records for best length, best score, recent sessions, daily challenge results, and the positions where mistakes happen most often. You can also adjust sound, haptics, symbol labels, theme choice, reduced motion, and demo speed.

Everything works without an account and without a network requirement for the core experience. The app does not make claims about intelligence, health, or professional ability.
