Read full description

The power and beauty of time—felt in every step, every turn of the stone. Sisyphus is a living Greek landscape for iPhone: classical black-figure bodies, finely animated movement, and time tools that stay with you on the hill. Choose Sisyphus or Aphrodite. Walk, pause, and reflect while the clock—and your intention—remain in view. FREE TO USE • Walking Sisyphus and Aphrodite’s Garden • Current-time Clock on the journey (always free) • An Antikythera clock you can show apart from the stone display • Four stone-clock designs, plus Antikythera mechanism and numeral choices • Nine languages, automatic or manual • Myth-inspired lines and character stories • Local records for distance, time, activities, honors, and wreaths • Seasonal scenery, a sky that follows the hour, sound, haptics, and visual alerts FULL SISYPHUS — ONE-TIME PERMANENT UNLOCK • Eternal Ascent: choose boulder weight, size, material, and slope, then continue the complete journey • Random Sisyphus: walking, running, jumping, flight, prayer, and rest shaped by time, season, and sky • Thinking Sisyphus and Thinking Aphrodite: quiet scenes for reading and reflection • Focus Timer for study, work, and deep work blocks • 24H Plan with alerts at the start and end of selected time blocks • D-Day with a custom title, target date, and alerts • Assign Clock, Timer, 24H Plan, or D-Day separately to the stone and to Antikythera This is not a subscription.
