## What is Zone 2 Buddy?

Zone 2 training only works if you actually stay in Zone 2. Zone 2 Buddy taps your wrist the moment you drift — down-taps to ease off, up-taps to push — so your easy days build an aerobic base instead of turning into junk miles.

Start a workout on your Apple Watch, put your phone in your pocket, and train by feel. No account. No sign-up. Your health data never leaves your devices.

HOW IT WORKS

• Set your zones in under a minute — percentage of max heart rate, or the Karvonen (heart rate reserve) method using your resting HR straight from Health
• Pick your sport — 82 workout types, from outdoor and indoor cycling to running, rowing, hiking, swimming, strength training, and skiing
• Train — distinct haptics for too-high and too-low, plus optional spoken alerts that duck your music instead of stopping it
• Every session saves as a real Apple Health workout with heart rate, calories, distance, and GPS route. It closes your rings and shows up in Fitness.

FREE

• Real-time zone alerts on Apple Watch — haptic and spoken
• All 82 workout types with GPS route recording
• Workouts written to Apple Health
• Five-zone setup with two formulas
• Workout history with time in zone for every session

ZONE 2 BUDDY PRO

• LIVE DASHBOARD — mount your iPhone on the handlebars for big, glanceable heart rate, zone, speed, and distance streamed live from your watch
• WEEKLY TRENDS — time-in-zone charts week over week, so you can watch your aerobic base build instead of guessing
• WEEKLY RECAP — a plain-English read on your training week, generated entirely on your iPhone with Apple Intelligence. Nothing is uploaded.
• CUSTOM ZONES — tune every zone boundary to your own physiology
• LIVE ACTIVITY — heart rate and zone on your iPhone Lock Screen and in the Dynamic Island while a watch workout runs

WHY ZONE 2

Most endurance adaptation comes from long, easy efforts. The hard part isn't the training — it's the discipline to keep the effort low when you feel good. Zone 2 Buddy is the thing on your wrist that keeps you honest.

PRIVACY

There is no Zone 2 Buddy account and no analytics server. Heart rate and workout data stay on your iPhone and Apple Watch.

Requires an Apple Watch. Weekly Recap requires an Apple Intelligence-capable iPhone.

Zone 2 Buddy Pro is available as a monthly or yearly subscription, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple Account.

## Version history (last 5 releases)

### 2.0 — 2026-11-06

The biggest update since launch. Zone 2 Buddy now records the workout instead of just watching it.

REAL WORKOUTS ON YOUR WRIST
Start on Apple Watch and every session saves as a genuine Apple Health workout — heart rate, calories, distance, and GPS route. It closes your rings and shows up in Fitness alongside everything else.

PICK ANY SPORT
All 82 Apple Watch workout types are now startable, indoor and outdoor, each with the right distance metric and route recording — cycling, running, rowing, hiking, swimming, skiing, strength, and the rest.

SPOKEN ZONE ALERTS
Optional voice coaching that calls out your heart rate and whether to ease off or push. It ducks your music instead of stopping it.

BETTER ZONES
Set zones by percentage of max heart rate or the Karvonen (heart rate reserve) method, pulling your resting HR straight from Health. Zone boundaries are more accurate, and they persist properly across devices.

HISTORY
Every workout, with time spent in each zone, distance, calories, and route.

A NEW LOOK
Redesigned first-run experience that actually explains Zone 2 training, plus a new app icon.
