Happy High!

Healthy highs. Naturally.

Free · In‑App Purchases · Designed for iPhone

Every fitness app tells you what to do. Happy High! tells you when you feel good - and helps you get there faster. Your body has built-in mood technology. Scientists call it the endocannabinoid system - a network that produces your own "bliss molecule" called anandamide. When you exercise at the right intensity, this system activates, creating natural feelings of euphoria, reduced anxiety, and enhanced wellbeing. The problem? Most people exercise at the wrong intensity to trigger it. Go too easy, and nothing happens. Go too hard, and stress hormones overwhelm the effect. Happy High! solves this with real-time heart rate tracking that shows you the exact moment you enter your Happy High Zone - 70-80% of your max heart rate - where the magic happens. HOW IT WORKS - We calculate your personalized Happy High Zone based on your age - Start any activity - running, walking, cycling, dancing - Watch your heart rate in real-time - Feel a vibration alert when you enter the zone - Track your "time in zone" as it accumulates - Enjoy the afterglow - mood benefits that last for hours THE SCIENCE For decades, we thought "endorphins" caused the runner's high. Research now shows we had it wrong. Studies from Johns Hopkins and published in PNAS demonstrate that endocannabinoids - not endorphins - are primarily responsible for exercise-induced euphoria. Unlike endorphins, which are too large to easily cross the blood-brain barrier, anandamide (your bliss molecule) directly enters your brain when triggered by moderate-intensity exercise. Happy High! puts this science in your pocket. KEY FEATURES Real-Time Heart Rate Tracking See your BPM update live during any workout. Know exactly where you are relative to your zone.
