Tera 7.83

Tera 7.83 is a meditation timer — no spoken guidance, just phases (Calm, Meditate, Come Out) marked by chimes so you can sit with your own practice. What makes it different: the audio is built around the Schumann Resonance, the 7.83 Hz electromagnetic hum produced between the Earth's surface and ionosphere — sometimes called "Earth's heartbeat." Binaural audio guides your brain toward that frequency, while gentle haptic pulses give your breath a rhythm to follow. The Premium unlock ($6.99, one-time) adds heart rate insight: it pairs with your Apple Watch, which auto-launches alongside your iPhone and samples your heart rate roughly every 5 seconds throughout the session. Afterward, you get a phase-by-phase HR chart showing how your body responded — before, during, and after — plus session history synced via iCloud to track trends over time. - Free to start, no account required - Chime-marked phases with haptic breathing guidance - iPhone + Apple Watch (auto-launch, no interaction needed on the Watch) - Premium: post-session HR phase chart, session history, trend tracking - Privacy-first: HealthKit data stays on-device, no third-party tracking or ads Available on the App Store: https://apps.apple.com/app/tera-7-83/id6781022637 Free Premium unlock code for the first 100 people — fill out this quick form: https://forms.gle/FfAr7NpcTN5hbwETA
