Breathwork vs PostureFit Agent

Most breathwork apps want your email, your name, and a year-long commitment before you've taken your first breath. Tether does the opposite. Open the app. Pick a goal. Take three minutes. That's it. LIVE BIOMETRIC FEEDBACK If you wear an Apple Watch, Tether reads your heart rate and HRV in real time during sessions. Watch your numbers drop as your nervous system shifts. Health data stays on your device — your metrics never leave your phone. GUIDED BREATHING THAT ACTUALLY GUIDES Twenty exercises across four categories — Calm, Sleep, Energy, Recover. From Box Breathing for focus to Wim Hof for activation, each one has a voice guide, breath sounds, and an ambient soundbed. Three duration tiers (3, 5, or 10 minutes) so a session fits whatever time you actually have. THE LIVING ORB The breathing visualization is a hand-tuned canvas that pulses with your inhale and exhale. Not a video, not a stock animation — calculated frame-by-frame so it stays in lockstep with the audio guide. JOURNEY DASHBOARD Track your streak, see HRV trends over weeks, get a monthly recap shareable in one tap. Synced privately to your iCloud — no account, no backend. SEND A CALM Tap once after a session to send a friend a 60-second guided breath. They get a real Tether session right inside Messages, via App Clip — no install required.
