Base: Zone 2 Cardio Tracker

Base counts your weekly zone 2 minutes from Apple Health — across recorded workouts and qualifying everyday activity — so you can see where your week stands without adding up sessions yourself. YOUR WEEK, ALREADY COUNTED Connect Apple Health to follow your zone 2 minutes against a goal you choose. Outside a recorded workout, activity needs sufficiently frequent heart-rate readings and supporting Apple Exercise Time. Unsupported gaps do not count; Base does not credit every movement. STAY IN YOUR ZONE Start an optional workout in Base on Apple Watch for live guidance in your personalized zone. Follow your session on your wrist or its mirrored iPhone display. SEE WHAT COUNTED Explore the walks, runs, rides and qualifying everyday activity that contributed. Look back through your history and follow your consistency over time. ONE GLANCE AWAY Keep your weekly progress visible with iPhone widgets and Apple Watch complications. YOUR HEART, OVER TIME See resting heart rate and HRV trends alongside your zone 2 activity. Personal trends, not a diagnosis or a promised health outcome. PRIVATE BY DESIGN Your heart-rate readings, workout records and measured zone 2 totals are processed on your devices, not sent to our analytics services. Usage analytics and crash reporting are optional and off until you agree. No Base account required. Base needs compatible heart-rate data in Apple Health, with workout records or supporting Apple Exercise Time for qualifying activity. Live workouts require a compatible Apple Watch.
