Your body already knows what to do. It's just waiting for the signal. Sleep better. Boost your energy. Manage stress, strengthen immunity, stay focused. No gadgets, no guru: ancestral protocols — cold, breath, fasting, stillness — backed by science, guided step by step. 100% free. Modern comfort made us forget what the body has always known: how to use cold, breath, deprivation and stillness to repair and grow stronger. HÄK isn't another coaching app — it's a reminder. A biological wake-up call. HÄK brings together ancestral practices — those of the Samurai, the Stoics, the Vikings — and validates each one with science (PubMed, meta-analyses, clinical trials). No pseudo-science. No magic promises. Just what has worked for millennia. THE HÄK METHOD — THREE BIOLOGICAL LEVERS THRESHOLD — the art of controlled stress Cold, effort, fasting. Your body adapts and becomes antifragile. (Cold shower, Wim Hof breathing, intermittent fasting.) MATTER — the art of good input Light, water, dense food. You're literally built from what you take in. (Morning sun, conscious hydration, functional nutrition.) ANCHOR — the art of regeneration Breath, sleep, presence. The parasympathetic system repairs and rebuilds. (Heart coherence, evening ritual, meditation.) WHAT'S INSIDE • Immersive widgets that guide you step by step — never a protocol left to interpret • Multi-mode timer: countdown, stopwatch, intervals, EMOM, AMRAP — from Tabata to 16/8 fasting • 5 guided breathing exercises with animation and synced haptics: Box 4-4-4-4, 4-7-8, Wim Hof, Coherent, Physiological Sigh • Binaural soundscapes for focus, meditation, sleep, alertness and relaxation (Alpha, Theta, Delta waves — headphones recommended) • Decibel meter for vocal-release practices • Learn cards: origin, science, myths and sources for every practice • Expert Sessions: complete 3-to-5-practice protocols in the right order (Deep Sleep, Deep Work, Vagal Reset, Immune Armor…) • Free Mode to build your own session • Persistent timers: your 16/8 fast keeps running even when the app is closed • A personalized routine based on your goals, with gentle reminders — never spammy LEARN → PRACTICE → REPEAT Understand the why. Follow the guided protocol. Anchor the habit. Knowledge becomes the act, the act becomes instinct. DUAL VALIDATION Every practice passes two tests: ancestral heritage (they already did it) and scientific evidence (now we know why). Both are mandatory. 100% FREE Every practice, every widget, every Expert Session — no subscription, no credit card. HÄK is completely free. Cold awakens. Deprivation builds. Calm repairs. Rediscover what the body already knows. Welcome to HÄK. Our very first release is here. Reawaken your biological intelligence with ancestral protocols backed by science: cold, breath, fasting, sleep, stillness. We just launched — tell us everything at contact@hak-method.com.

Verdict
The clearest difference is update cadence: HÄK at fortnightly against Sofrocay's every 6 weeks. Sofrocay's advantage is iOS requirement (13.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
