Zener Game

A calm, meditative app to explore extrasensory perception (ESP) with the five classic Zener symbols. Train your intuition and see if practice really matters.

Zener Game is a minimal, meditative app to explore and train your intuition using the five classic Zener symbols: circle, cross, waves, square, and star. Inspired by the deck designed in the 1930s by psychologist Karl Zener for extrasensory perception (ESP) research, the app replaces physical cards with an algorithm that picks a symbol each round. Your task is to perceive which one was chosen and tap it. No physical deck, no pressure — just you, five symbols, and a quiet moment of focus. FEATURES • Two deck modes — Random: each symbol is drawn independently. — Balanced: a shuffled virtual deck with an equal number of each symbol, closer to the classic paper test. • Flexible sessions Choose 10, 15, 25, 50 rounds, or set any custom number from 5 to 200. • Customisable feedback Three independent toggles let you decide what to see during play: round counter, hits & accuracy, and whether to reveal the correct answer after each choice. Turn them all off for pure intuition. • Rich statistics Every completed session is saved locally. Track sessions, total rounds, average and best accuracy, longest streaks, and per-symbol performance. • Scientific color mode An optional setting switches the colour thresholds from simple to statistical: green appears only when your result is statistically unlikely to be chance (outside ±2σ of 20%). • Calm audio Soft ambient background music and gentle tap sounds, both independently toggleable. • Export your data Generate a clean text report of all your statistics and share it anywhere. DESIGN Zener Game is designed to feel like a quiet moment. Warm cream paper, Japanese-inspired minimalism, hand-crafted symbols, soft serif typography. Nothing screams for attention — everything invites focus. PRIVACY All your sessions are stored locally on your device. Nothing is uploaded, no tracking, no analytics. Your intuition is yours alone.
