Slog vs Monk

Slog — Zone 2 cardio you can glance at, not squint at. Just say "Hey Siri, Start Zone 2." A workout begins. Your wrist turns green when you're in Zone 2, blue when your heart rate is too low, red when it's too high. That's the entire app. No reading numbers mid-stride. HOW IT WORKS 1. Voice start. No tapping, no menus. Say "Hey Siri, Start Zone 2" from across the room. 2. Glance for color. Full-screen color tells you what to do — speed up, slow down, or hold steady. No squinting at a heart-rate number while running. 3. End when you're done. Workouts save to Apple Health and count toward your Fitness rings. WHY ZONE 2 Zone 2 is sustained aerobic work at 60–70 percent of your max heart rate — what exercise physiologists call conversational pace. It's the foundation of cardiovascular fitness, supported by decades of research and recommended by the American Heart Association. The catch: it's hard to stay in Zone 2 without a tool. Most apps bury heart rate behind charts and zones 1 through 5. Slog shows you one thing — are you in Zone 2 or not — and gets out of the way. WHAT'S IN (THE WHOLE APP) — Voice-activated workout via "Hey Siri, Start Zone 2" — Full-screen color UI: green, blue, red, gray — Heart rate displayed as a fallback number — Elapsed time — Auto-calculated Zone 2 from your age in Apple Health, or set manually — Workouts saved to Apple Health and Apple Fitness rings — Watch face complication for one-tap launch — Haptic taps when you cross zone boundaries ON YOUR IPHONE Your phone is the treadmill console. During a watch workout, Slog on iPhone mirrors your heart rate live — a big number, a full-screen color, and your elapsed time, readable from feet away. Afterwards, History shows every session with time in Zone 2 and your weekly minutes against the 150-minute aerobic target. Set your range once in Zones (age-based, or Karvonen if you know your resting heart rate) and sync it to your watch with one tap. WHAT'S NOT IN (INTENTIONALLY) No multi-zone display. No splits, no intervals, no audio cues, no Strava bridge, no chest-strap pairing. Saying no is the product. PRIVACY Heart rate stays on your device. There's no account, no servers, no analytics, no tracking. Slog reads from Apple HealthKit and writes your workouts back to it. That's it. PRICING Free.

Your practice stays on your iPhone unless you choose cloud sync and Sign in with Apple. Export your record when you want a copy. No ads in the app, and no tracking across other companies' apps and websites. To see whether our Facebook and Instagram ads work, Monk uses Meta's SDK outside the EU/EEA, the UK and Switzerland: Meta learns when Monk is installed and opened and for how long, with a random install ID and basic device and network details (which can show your approximate area). Meta never gets your advertising ID or anything you record. You can turn this off in Settings. TRY IT FREE FOR 7 DAYS Monk is free to download. Start the free 7-day trial and everything works. After that, starting or logging anything new needs Unlock Monk, a single in-app purchase. What you have recorded stays yours to see and export. If you bought Monk before, everything stays unlocked. Monk is a tool for self-mastery and reflection, not medical advice or treatment.
