The moment you exceed your target zone, a gentle wrist tap reminds you to ease up — no glancing at your watch, no fumbling with buttons, just pure focus on every stride. WHY CONTROL YOUR HEART RATE? Running isn't about going as fast as possible. Staying in the right heart rate zone builds aerobic fitness more effectively, so you run easier and healthier. HEART RATE ZONE GUARDIAN Choose from preset zones — warm-up, fat burn, aerobic, and more — or fully customize your own. When your heart rate drifts out of range, Apple Watch vibrates instantly, keeping you in a safe and efficient training intensity. Your heart matters more than your pace. BUILT-IN CADENCE METRONOME An adjustable metronome provides rhythmic cues to help you maintain a steady cadence. A higher cadence can reduce over-striding and lower impact on your knees and Achilles tendons. YOUR DATA STAYS YOURS All workout data is saved to your personal iCloud through Apple Health. We never collect or upload any personal information. Even if you uninstall Speedown, your complete workout history remains in Apple Fitness. Speedown requires an Apple Watch to use.
