A smart, lightweight Windows desktop app that protects your eyes from screen fatigue using the 20-20-20 rule.
Every 20 minutes, take a 20-second break and look at something 20 feet away.
This app makes sure you actually do it — no skipping, no cheating. 💪
202020Pro is a personal wellness companion built with C# (.NET Framework 4.7.2) and DevExpress components.
