Everybody breathes. Few do it right. Logic Breathing gives you 23 science-backed breathing patterns — each just 60 seconds. No 10-minute sessions. One minute to shift your nervous system. Why 60 seconds? Elite runners synchronize breath to stride in sub-minute cycles. Research on breathing cadence shows your autonomic nervous system responds in seconds, not minutes. We designed every pattern to deliver a measurable shift — in heart rate, cortisol, or mental clarity — before your coffee gets cold. One minute. One pattern. Pick your state: → Can't sleep — 4-7-8 Sleep (Dr. Andrew Weil's clinically studied technique) → Stressed before a meeting — Box Breathing (used by Navy SEALs) → Need to focus — Cyclic Sighing (Stanford-validated, outperformed meditation — Huberman et al., 2023) → Heart rate too high — Resonance Breathing (HRV optimization at 6 breaths/min) → Headache coming on — Headache Relief (relaxes cranial tension, boosts cerebral oxygenation) → About to train — Pre-Workout (sympathetic priming) → Spiraling — Calming Vortex (Fibonacci-inspired deceleration from agitation to calm) → Brain fog — Brain Fog pattern (sharpens cognition in under 60 seconds) → Plus 15 more for recovery, running, freediving, lifting, immune support, and craving control How it works: Pick a pattern. Press start. Follow the visual, audio, and haptic guide through each inhale, hold, and exhale. Done in 60 seconds. → Daily reminders so breathing becomes a habit → Apple Watch support — guided breathing on your wrist Logic Breathing changes your body and mind in one minute.

About

ISOBEAST

Stop logging dynamic repetitions for a static workout. Muscles respond to tension, and isometric bar training is the ultimate way to build raw, injury-resistant strength. But standard fitness trackers are built for dynamic gyms. They do not understand force-based holds, strap-slot heights, or the precise progressive overload rules required for true isometric gains. Enter ISOBEAST. ISOBEAST is a premium, high-contrast training log designed specifically for isometric bar (ISO-BAR) equipment. By tracking exact force, hold duration, and strap slot positions (1–36), ISOBEAST removes the guesswork and guides you through deterministic progression rules to ensure consistent, measurable strength increases. PRECISION ISOMETRIC LOGGING Log force, hold duration, and exact ISO-BAR hook slots (1–36) to record performance at specific muscle lengths. The speed-first UI lets you log a set in under three taps. DETERMINISTIC PROGRESSION ENGINE ISOBEAST automatically scores sets (Success, Neutral, Failure) and updates targets using transparent rules like double progression, time-target holds, and average-capacity tracking. BUILT-IN ISO-BAR / ISOCHAIN / ISOMAX PROGRAMS Load read-only training templates straight from the manual: • The Promethean (6-second holds with double progression) • 6x6 (fixed percentage of tested 1RM) • Military Power (max-effort singles with slot variation) • Iron Man (long holds for conditioning) • One-Rep Max Testing (averages peak force attempts) DEVELOPER-PREMIUM UX • Pre-filled target inputs based on previous session data. • Custom haptic logging alerts for clear tactile confirmations. • Automated rest timers with skip commands and background notifications. • Persistent Active Workout banner to resume or discard sessions safely. PR VAULT & TRENDS Track your all-time bests per slot/mode and watch your strength curve rise with interactive volume charts. SECURE SYNC & PRIVACY ISOBEAST securely stores your profile, routines, and workout logs in a private cloud database. All logins and tokens are encrypted and kept in the iOS secure keychain. We collect no tracking data and never sell your personal information. Unlock true tension-based strength. Track with ISOBEAST. Terms of Use: https://isobeast.app/terms/
