Northpace

Northpace is a focused fitness and wellness app that does three things well, with no social feed, no streak pressure, and no upsells — open it, do the work, get on with your day.

• Norwegian 4x4 — the interval protocol from published cardiovascular-fitness research: warm-up, then four rounds of four minutes hard and three minutes easy, then a cool-down.
• Breath — twelve guided breathing patterns, from Tummo Breathing and Box to Resonance, 4-7-8, and Buteyko. Phase-boundary haptics let you practice with your eyes closed, on iPhone and Apple Watch.
• Rucking — an open-ended weighted hike with GPS distance, pace, and elevation, a heart-rate-zone route map, and calorie estimates that account for your pack weight, the terrain, real-time hills, and your heart rate — shown live on your Apple Watch.

Every workout is heart-rate-zone driven, takes live heart rate from your Apple Watch, AirPods Pro 3, or a Bluetooth chest strap, and saves to Apple Health when you finish.

Private by design. Northpace has no account, no ads, and no analytics. Your heart rate, workouts, location, and audio stay on your device and in your own Apple Health — the developer never sees them. See the Privacy Policy for details.
