Get Zone 2 right.
Push your VO2 Max up.
Your watch reads the heart rate; a buzz on the wrist holds the intensity — you know you have drifted out of the zone without looking at a screen. Put the phone on the floor and it is a full dashboard you can read from two metres away.
Cut the clutter, keep the core.
The fancier the feature list, the less of it you actually touch once you are in the gym or the box. KINETIC does three training modes.
No type, no duration. Press start and the timer runs from zero until you end it — heart rate, time in each zone and calories recorded end to end. Open the record any time afterwards and write down what you did: a note, a photo, or the WOD detail.
A timed aerobic session with a target zone. One buzz when you enter the zone, two when you drop out — no need to watch the screen, so you can spend the whole session where you meant to be. Aerobic base, built properly.
Structured intervals: Norwegian 4×4, or the Assault Bike 60s Death Set for days you do not want to run. The watch buzzes at every segment change and counts each one down, switching between sprint and active recovery — the most efficient way to raise your VO2 max.
Give your attention back to training.
Let the buzz keep time.
Gyms and boxes are loud and badly lit, and your hands are busy under a barbell — so KINETIC's primary cue is a buzz on the wrist. The screen is there for a glance out of the corner of your eye.
Entered the target zone · pace is right, hold it
Dropped out of the zone · glance at your wrist and pull it back
Interval segment change · sprint, recovery, cool-down — you know the moment it switches
Phone dashboard · oversized BPM digits, flat on the floor, readable from two metres away
Cool down. Read the whole session.
Every session ends with a full record generated for you: heart-rate curve, time in zones, total duration, calories, average and max heart rate. WOD detail and photos from an open session can go in any time afterwards; you can also export a share card so what you did reads at a glance.
Hit a new max heart rate? The app asks whether to update it — and recalculates your zones for you.
Your zones come from your data, not a formula.
You do not have to memorise a formula — the app supports max heart rate (MHR), heart-rate reserve (HRR) and lactate threshold (LTHR), and Auto picks the most accurate method your data supports. Resting heart rate and heart-rate recovery come straight from Apple Health.
Put the phone away. The data keeps coming.
Lock Screen and Dynamic Island
A Live Activity starts automatically during a session — pocket the phone or lock the screen and BPM, zone and the countdown carry on showing on the Lock Screen and in the Dynamic Island.
Watch face complications
Complication layouts for Apple Watch, so KINETIC is one tap from the watch face — pick a mode and start.
Apple Health
Every session is written to Apple Health, and resting heart rate and heart-rate recovery come back the other way to build zones that fit you.
