l'orange

Train smarter. Live longer. Your heart knows the way.

l'orange turns your Apple Watch into a focused heart-rate training tool. It guides you into the "Orange Zone" (80–90% of your max heart rate) and counts every Orange Minute you earn toward a weekly goal.

WHY THE ORANGE ZONE?

Time at higher intensity is one of the most effective ways to build cardiorespiratory fitness (VO₂ max), and higher fitness is strongly associated with a longer, healthier life. l'orange keeps it simple: one zone, one weekly goal.

ON YOUR APPLE WATCH

• Live heart rate on a full-screen zone colour, with your percentage of max
• A haptic cue when you enter and when you leave the Orange Zone
• Pause and resume, then a clear summary of your time in every zone
• Rate how each workout felt
• Works on its own: no iPhone needed during your workout
• Every workout is saved to Apple Health

ON YOUR IPHONE

• Home: your weekly Orange Minutes fill a progress lens toward your goal
• History: a list and a calendar, with a day view
• Workout detail: heart-rate graph with zone bands, zone mix, 1-minute heart-rate recovery and, for outdoor workouts, your route
• Trends: Orange Minutes per week, resting heart rate, HRV, VO₂ max and recovery over time
• Set your max heart rate on iPhone, and your Watch follows
• Home Screen widgets and quick actions
