For fifty years, the two 355 m masts of the Liblice B transmitter near Český Brod were the tallest structures in the Czech Republic. On 15 October 2026 they were brought down with explosives. This app puts them back on the horizon through your phone's camera, aviation lights blinking.
Lights on the horizon
Stand anywhere with a view towards Liblice and point your phone at the horizon. Using GPS and the compass, the app lights up both masts where they stood, at the right height and in the same rhythm as before. Six levels of red lights glow steadily, two more flash, and a white strobe flickers on top. You won't see the structure itself here, only the lights remain, as a memorial. From far away they are small, so arrows and a white ring show you where to look. If the compass is slightly off, drag sideways to fine-tune the direction.
Liblice at home
Set up a model of both masts in augmented reality on your desk or in the garden. Pinch to resize or rotate it. Its lights blink just like on the horizon.
In both modes you can save a picture from the camera to your photos or share it. The home screen has a short history of the transmitter, key facts and links to learn more.
Locals called them simply tyčky, the sticks. I miss those blinking lights on the horizon, so I made this app as a memory of them. I'm sure many others will enjoy it too. The app is free, has no accounts and collects no data.

Fixed the Back and Share buttons not responding on some iPhones, and a crash when placing the model in Liblice at home.
