Shklanky v1.0.0
If you find yourself sitting at you computer, longing after regular chimes of ship's bell this is made for you. Coincidentally, it is not a bad idea to stretch or let your eyes rest every thirty minutes. 😉
You can choose to get a sound, a notification or both every time when the crew would ring a bell to indicate the passing of time. If you'd rather focus, there are a few convenient options to silence the extension.
The name "shklanky" is a transcription of Polish word "szklanki" [ˈʃklãnki]. The word usually means glasses (e.g. of water), but it can also mean ship's bell strikes that tell the crew what time it is now (like German "Glasenuhr").
