EchoTrace

An offline sequence memory game built for light entertainment and personal practice. Start with a guided tutorial that uses two symbols and a short three-step sequence. Then move into classic, reverse, and missing-step stages that scale up to longer runs with steady pacing. Classic mode grows the sequence one step at a time. Reverse mode asks you to recall the pattern backward. Missing-step mode hides one item and lets you restore it from candidate choices. The app tracks your best length, best score, recent runs, and common miss positions locally on the device. A daily challenge uses a fixed local sequence for the current date so you can practice the same run again later. You can adjust demo speed, sound, haptics, motion reduction, symbol codes, and theme preferences. Replay is available once before input, pause is supported during a run, and every stage includes clear feedback and recovery. The app works fully offline and does not require an account, cloud sync, advertising, or network access for play.
