This does not work with latest versions of Android. It seems to work up to Android 8 with some caveats. With Android 9 and up, the app can't access the matrix to reconfigure the city or any setting at all. You end up with a clock with weather info from London. Impossible to adjust anything. And the author is MIA.
hello, dude. I appreciate your great job. I wanna ask whether the clock could be an alarm with sound or increase its height by adding the LED dot matrix? I suggest that the clock could add the function of Bluetooth speaker.
