MetroRadar in Warszawa Nasze Miasto — an app that warns passengers about disruptions

On 27 June 2026, Warszawa Nasze Miasto published Greta Sulik's feature about MetroRadar. The article presents the app not only as a way to check disruptions, but as a response to a familiar passenger problem: information about suspended services often arrives only after someone has reached the station.

The feature connects the project's origins with regular journeys between the Wilanowska and Świętokrzyska areas. Repeatedly learning about problems too late provided the motivation to build a tool that could warn passengers earlier and leave time to change route.

The article explains that MetroRadar's creator works as a cybersecurity analyst and began learning programming after hours for this project. The first version was built in roughly three months and initially focused only on the Warsaw metro.

Coverage later expanded to trams, buses, SKM, Koleje Mazowieckie and WKD. At the time of publication, the app had around 7,000 users. The article also reports that nearly 1,700 people downloaded MetroRadar in one day after a recent metro disruption.

• M1 and M2 metro lines, stations and affected sections,
• tram and bus stoppages and diversions,
• SKM, Koleje Mazowieckie and WKD alerts in one place.

Warszawa Nasze Miasto also describes how MetroRadar combines official announcements with signals from passengers. One community report should not automatically trigger an alert for other users; additional independent confirmations help reduce spam and false alarms.

Coverage by a local news site offered a chance to explain why MetroRadar is not another journey planner. Its job is to warn passengers when the situation changes, show the source and provide a few extra minutes to make a sensible decision before leaving.
