Iris Guard от Leila

Iris reminds you to rest your eyes every 20 minutes using the 20-20-20 rule: look at something 20 feet away for 20 seconds. Simple, quiet, and effective.

KEY FEATURES

• Custom message — write your own reminder text or keep the default 20-20-20 prompt
• Preview button — test the overlay instantly before your next scheduled break
• Live countdown in popup — see exactly how many minutes until your next break
