## What is KINETIC Link?

Get Zone 2 right. Push VO2 Max up — this time on your sport watch.

KINETIC Link is the iPhone side of the KINETIC watch app, for sports watches: set your session up on the phone and push it to the watch; while you train, heart rate and zones stream back to a big phone dashboard; when you're done, the full report is on your phone.
(On Apple Watch? Look for "KINETIC: Zone 2 · VO2 Max" instead.)
KINETIC Link talks to our own KINETIC watch app. It does not control your watch's built-in features.

■ First, install KINETIC on the watch
Get the free KINETIC watch app on your sports watch, come back here, pick your watch, and you're linked.

■ Three ways to train

Open Session (OPS)
No type to pick, no time limit — it runs until you call it, and every second is recorded. Tap once each time you finish a rep and the count is kept for you.

Zone 2 (BASE)
The watch buzzes when you drop out of your zone, and again when you're back in — no staring at the watch. Aerobic base gets built exactly this way, session after session.

VO2 Max Intervals (PEAK)
Norwegian 4×4 and the Assault 60-second protocol built in — rounds, work and rest seconds all adjustable. The watch buzzes at every segment change, with a 3-2-1 countdown just before it.

■ Your phone on the floor is the dashboard
The clock is the hero; heart rate, calories and time in each zone sit below it. Turn the phone sideways and the numbers get big enough to read from two metres away.

■ Your own ceiling
In an open session, cross the heart rate you set and the watch buzzes right away, then every five seconds until you come back down.

■ Zones built from your numbers
Max heart rate, heart rate reserve or lactate threshold — with enough data, the most accurate method is picked for you. Got a table from your coach? Enter the five zone percentages yourself. Age, resting and max heart rate can come straight from Apple Health. Push once and the watch remembers — train on your zones even when the phone stays home.

■ Write it up whenever
Notes, photos and session detail (movement, sets, reps, weight) — add them to the report any time after you finish.

■ Every session, poster-ready
The verdict, your heart-rate curve and time in every zone, laid out on one share card.

■ Your data stays yours
No account, no sign-up, no server. Your records stay on your iPhone; 

■ About tipping
Optional tips inside the app for anyone who wants to support development. Every feature is free — tipping unlocks nothing.

Free — no ads, no subscription.

Requires an iPhone (iOS 17 or later), a smart watch paired with your iPhone, and the free KINETIC watch app . Supports 64 models. The watch shows Traditional Chinese or English, following your watch language.
