Hyud

Hyud is a macOS application that helps user take more frequent breaks (to reduce work fatigue), optionally do some tiny workout during those breaks (to avoid sedentary lifestyle and being seated for too long, which is extremely bad for health), monitor and fix their posture (so that they have more breathing capacities, less back pain, stand taller and look overall more confident) and finally help them block distractions by allowing them to block access to any websites.
