Ekidex

What does it really mean to know a city? Subway and train stations tend to cover a city almost entirely. So if you've stood in front of every single one, you've basically been everywhere. Ekidex turns that idea into a simple collecting game: take a photo of a station's exterior, name sign visible, and it's yours. • 469 stations across JR, Tokyo Metro, Toei Subway, and private railways • Easy mode for beginners: just the Metro + Toei subway network (about 285 stations) • Achievements, line stamps, and ward-by-ward progress to unlock • A real, hand-drawn street map of Tokyo that works fully offline • English and Japanese, light and dark mode No account, no server, no ads, no analytics. Your photos never leave your device.
