## What is Tether?

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, so you can see how your body responds during and after each one. Your health data is never sent to us or to anyone else; your session history syncs only through your own private iCloud.

GUIDED BREATHING THAT ACTUALLY GUIDES
Twenty exercises across four categories — Calm, Sleep, Energy, Recover. From box breathing for focus to breath-hold rounds for energy, 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.

PRIVACY-FIRST
We don't ask for your email. We don't ask for your phone number. We don't show ads. We don't sell your data — there's nothing to sell. Anonymous usage analytics only, fully disclosed in our Privacy Policy.
