Breva skips the usual breathing-app formula of animated circles and soft chimes and puts the rhythm directly under your fingertips: rest a hand on your MacBook’s Taptic trackpad and it taps out the cadence of whichever pattern you pick — Coherent, Box, Calm, or 4-7-8. No camera, no data collection, no screen to stare at while you’re trying to look away from screens. Free on the Mac App Store.
