Heart rate zone training, done right. Live zones on Apple Watch, full history on iPhone. No subscription. Limen, from the Latin for threshold. A heart rate zone training app for Apple Watch. See your zone live during workouts, review time-in-zone afterward on iPhone. TRAIN IN THE RIGHT ZONE Different intensities trigger different adaptations. Zone 2 builds aerobic base and fat-burning efficiency. Zone 3 develops VO2 max. Zones 4 and 5 push your lactate threshold and anaerobic capacity. Limen shows you which zone you're in - in real time, on your wrist. YOUR PERSONALIZED ZONES Five zones calculated from your max heart rate (estimated as 220 minus your age). Not generic targets - ranges built around your physiology. THE AFTERBURN EFFECT Intense exercise triggers EPOC - Excess Post-Exercise Oxygen Consumption - keeping your metabolism elevated for hours after you stop. Limen tracks your time in high-intensity zones as Burn Points. Aim for 12-20 per workout. APPLE WATCH + iPHONE - Live zone display during workouts - Time-in-zone breakdown for every session - Full workout history on iPhone - No subscription, no ads Limen is independent and free. If you find it useful, a tip from the tip jar keeps it that way.
