Peeka is a small ghost that lives on your Mac and gets sleepier while you work, so a break never comes out of nowhere. Every 20 minutes it waits until you stop typing, dims your screen for 20 seconds and suggests something far away to look at. It stays out of calls, screen shares and full-screen slides, and naps when you step away. Skipping is one key, with no streaks to lose. Native Swift, no account, no analytics.
