Metroji is a Czech app designed for iPhone users who frequently travel on the Prague metro. It offers convenient features that assist users in catching their nearest metro departures efficiently. The app displays the three closest departures, provides hints through emojis derived from ticket markers, enabling users to gauge if they need to hurry to catch the next train.

Moreover, Metroji works offline, ensuring functionality even without an internet connection. Users can also benefit from the widget and Apple Watch app, allowing quick access to metro information directly from the Lock screen or wrist, which is especially useful when in a rush.
