What's in the app

  • Fifteen tests

    Baseline (Simple, Auditory, F1, Reflex Duel), Choice, Executive (Go/No-Go, Stroop, Dual Task), and Dynamic (Moving Target, Peripheral Vision, Disappearing Act, Memory Reaction).

  • Offline by design

    No account to create. Session history, personal bests, streak, and settings stay on this device.

  • Practice, not diagnosis

    Timing starts when the cue appears and stops when you tap. Compare scores with your own history on the same device. This is not a medical device.

  • Train your way

    Daily challenge, training plans, difficulty, rounds, and Light or Dark appearance. iPad layout with Split View.

  • Share when you want

    Export or share a result only when you choose to. Nothing is uploaded by the app.
