Slog vs Zone 2 Training App

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.

Zone 2 Heart Rate Training Tracker Train smarter, build endurance, and improve stamina with a simple heart rate training app designed to help you stay in the right heart rate workout zone. Zone 2 helps you track how much of your weekly workout time is spent in the zone 2 heart rate training range, typically around 60–70% of your maximum heart rate. This lower-intensity training zone is widely used by runners, cyclists, athletes, and fitness enthusiasts to improve aerobic fitness, support fat-burning efficiency, and build long-term endurance without overtraining. Whether you are working on pacing, stamina, VO2 max, or overall cardiovascular fitness, Zone 2 makes it easy to understand your heart rate training zones and track your progress over time. Track Your Heart Rate Zones See how much time you spend in each heart rate training zone during your workout: • Zone 1 – Easy recovery • Zone 2 – Aerobic endurance and fat-burning • Zone 3 – Moderate tempo training • Zone 4 – High-intensity threshold training • Zone 5 – Maximum effort and VO2 max training With clear heart zones, you can better understand your effort level and train with purpose. Built for Zone 2 Training Zone 2 heart rate training is one of the most effective ways to build endurance, improve stamina, and create sustainable fitness gains. The app helps you stay consistent by showing your weekly zone 2 minutes and helping you aim for 150 minutes or more of weekly zone 2 exercise. Your ideal zone 2 target may vary based on your fitness level, age, and goals, but tracking it consistently can help you improve your aerobic base over time. Live Heart Rate Workout Tracking Use Zone 2 during running, cycling, walking, gym workouts, cardio sessions, or any heart rate workout where pacing matters. If you have an Apple Watch, you can track your heart rate zone progress directly during your workout. If you do not have an Apple Watch, you can connect common Bluetooth heart rate monitors such as Polar H10, Garmin chest straps, and compatible Garmin watches to view your heart rate zones live.
