Free to download. Pro is $4.99/month or $49.99/year, and both start with a 7-day free trial.
Every finished workout is distilled into what actually happened — the lift you swapped out, the set you cut short, the day you finished twenty minutes early, the movement you rated down twice. That record is in front of him the next time you talk — the post-workout note, the question you ask mid-set. And what you rated down twice doesn't come back: two thumbs-down and the app pulls that movement out of your plan and out of workouts already on your calendar.
Post-workout notes reference where a specific lift was weeks ago, not a generic "great job."
Rate a movement down two sessions running and it stops appearing. Excluded lifts are stripped before a session ever reaches you.
Ask for a lighter top set, a different lift, or why today's rest is 150 seconds. His answer applies to the session you're standing in.
Your last two bench sessions both ended at 185, and the final set was slower each time. We're holding 185 today and adding a set instead of weight.
You've swapped out the pec deck three weeks running, so it's off the list. Cable fly in its place.
Most apps hand you a workout. Kinetics hands you a position in a plan. Each phase has its own set and rep character, its own rest, its own effort range — and the app tells you which one you're in, which week of it, and what comes next. Foundation runs once, to calibrate. After that the cycle repeats.
Want to sit in Hypertrophy indefinitely with a chest-and-back emphasis? Turn off the clock and stay there.
Kinetics plans the whole week's split first, then the sessions, so your pulls, pushes and hamstrings balance across the week rather than per day.
A 45-minute session counts the real rest between sets. Ask for 45 minutes in a Strength phase and you get fewer exercises, not a session that secretly runs 70.
The Kinetics Watch screen mid-set. The pinch hint under the button appears on watches that support double-tap.
Hit start and the Watch app comes up on its own. The set you're on, the weight, the reps, the rest clock and your heart rate are all on your wrist from there — so for a normal session in the gym, that's the last time you pick the phone up.
Pinch your finger and thumb twice to finish the set, skip the rest, or start and stop a timed hold. Chalk, gloves, a loaded bar — nothing has to touch a screen.
Needs watchOS 11 and an Apple Watch Series 9, Ultra 2 or newer. On older watches it's a button on the same screen.
It counts down on the Watch itself instead of waiting on your phone to push every second, and taps your wrist through the last five. You look up when the set starts, not thirty seconds after.
The Watch tells your phone what you did; it never sends a copy of your log back. So a stale watch can't overwrite sets you've already recorded — the most common way a lifting app loses your work.
Live BPM on your wrist, written to Apple Health, and folded into the intensity breakdown on your post-workout report.
Pause, skip and the full exercise list are all on the wrist. Reopen the app mid-workout and it lands on the exact set you're standing on.
The Watch works with your phone, not instead of it. Keep the phone in the room — taps sent while it's out of range for more than a minute don't make it back. The Watch moves you through the sets at the prescribed reps and weight; changing a number is still a phone job. Auto-launch needs permission to write workouts to Apple Health.
Chalk on your hands, a bar to load, forty-five seconds of rest left. You should not have to unlock a phone to find out what's next.
At the top of every rest, your next exercise, weight and reps are spoken aloud, so you can load the bar while the clock runs.
With AirPods in, a double-nod completes the set. Sensitivity is adjustable and there's a guided calibration.
Coach K walks you into the session and names what you're working on today, in his voice, before the first rep.
Both hands-free features are off by default. Settings › Audio Cues and Settings › Hands-Free.
Not "machines" and "cardio equipment." Lat pulldown, leg press, hack squat, pec deck, leg curl, rower, SkiErg — named, so a session never asks you for a piece of kit that isn't in the building.
Save separate profiles for the commercial gym, the garage rack and the hotel. Switch and the programming follows.
Filter the whole library by muscle group, difficulty, or just My Gear. Every entry carries form notes and its equipment requirement.
Rack taken? Replace any lift with a same-muscle alternative you have gear for. Sets, reps, weight and rest carry over.
Mark the days you're away. The week gets scheduled around them and your streak pauses rather than breaking.
Sets, reps, total volume, intensity, muscle activation, heart-rate range, and every personal record with the estimated one-rep-max change next to it. Then the volume trend, so you can see whether the block is doing what it's supposed to do.
Spots a lift that hasn't moved in three weeks, flags it, and offers a one-tap weight bump or rep progression.
A weekly written take on your last eight weeks, with every metric tappable down to the chart underneath it.
Sleep, HRV and resting heart rate come in from Apple Health and score your readiness, with sub-scores so you know which one is dragging. It's a reading you act on — you decide whether to push or back off. Your training load and how you rated recent sessions are what feed the next week's plan.
Six sessions in seven days, or a run of workouts you rated brutal, and Coach K writes the next one lighter — roughly 10–20% off the weights and about a third fewer sets. Triggered by how training is actually going, not a recovery week pencilled into the calendar.

A photo, or a sentence. Either works.
