About Speedown - Heart Rate Alert
Speedown monitors your heart rate in real time via Apple Watch. 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. Questions or suggestions? Feel free to reach out via the in-app feedback.
What’s new
Version 1.7 · Updated September 28, 2026
- New start screen on Apple Watch: after tapping RUN, pick Warm-up, Fat Burn or Cardio, or turn the Digital Crown for a custom heart rate target (Pro). The indoor/outdoor switch has moved to this screen's top-right corner - New workout history on Apple Watch: tap the bottom-left button on Speedown's main screen to review recent workouts, including distance, time, pace, route and average heart rate. Older workouts are on your iPhone - Redesigned post-workout summary on Apple Watch, now with your outdoor route, matching the new workout history - iPhone onboarding now helps you set a heart rate target - If another app takes over the workout session, Speedown now lets you know and keeps timing and the metronome going, but stops vibrating on a frozen heart rate reading - Workouts resume more reliably if Speedown quits unexpectedly, with more accurate pause state and duration - The metronome now retries automatically when another app is using audio - Fixed the zone name under the ring on the watch always showing Cardio - Fixed the first Digital Crown turn in watch settings switching a preset zone to Custom without changing the number (or skipping a value)
