Alarm clock

I always wanted to have a simple alarm clock on a computer that would live quietly in my tray, because I could not find one like this, I painted it myself in the hope that someone could translate. Comrades, developers of air applications, are there any interested persons? The alarm clock will naturally be free and accessible to everyone!
