stretchly is a cross-platform electron application that reminds you to take breaks when working on your computer. By default, it runs in your tray and shows a reminder window every 10 minutes to remind you that you need to take a microbreak. Every 30 minutes, it displays a window that notifies you about taking a longer break. You can pause and resume the break reminders. You can also skip to the next break or microbreak anytime from the menu, or reset the breaks.
