Breakly is a menubar app that uses macOS's native notifications system to remind you to stand up every 20 minutes or so.
Use it if you are:
- Looking to save your eyesight with the 20-20-20 rule
- Looking to combat the negative effects of sitting with the stand two minutes every twenty minutes rule
- Or just have trouble remembering to take a break every once in awhile.
