Your next panic attack won't wait for you to find your meditation app. But your breath? That's always with you. Undulate turns your phone into a breathing coach that actually works — 5 modes, haptic guidance, 60 seconds to calm. No account. No subscription. Ever. 60 SECONDS. REAL TECHNIQUES. These aren't random animations. Every mode is built on a real breathing technique used by doctors, military, and therapists: - Paper Plane — Box breathing. The technique Navy SEALs use to stay calm under fire. Balanced 4-4-4 rhythm that stabilizes your mind when pressure hits. - Whale — 4-7-8 breathing, developed by Dr. Andrew Weil. Activates your vagus nerve and drops your heart rate in under a minute. - Dandelion — Extended exhale for winding down. Shifts your nervous system from fight-or-flight to rest-and-digest. - Shredder — Fast-paced release breathing for when you're angry, overwhelmed, or about to lose it. - French Press — Slow morning breathing ritual. Better than coffee for waking up your brain. FEELS LIKE NOTHING ELSE Haptic feedback pulses with every inhale and exhale — your phone literally breathes with you. No screen-watching required. Just feel the rhythm and follow it. Every session is tracked. Streaks, minutes, modes — see the proof that you're building a real habit. PAY ONCE. KEEP FOREVER. Two modes are free. Unlock everything with a single purchase. No subscription. No renewal. No "we'll charge you when you forget." You pay once, you own it. We don't collect your data. We don't have accounts. We don't know who you are and we don't want to. Start now.
