It changes the plan.
It shows the number.
Lifting, running, food and sleep on one log.
Separate apps can't see each other, so none of them can
decide.

Every figure below is on the screen above
A morning it changed the plan.
Two readings under your normal, one change, one reason. In the

Why
Coach
Slept 5:42 and resting HR is 6 over your usual 52 —
I'd keep today easy.
Nothing changes silently. Every adjustment
carries its reason, and the coach has an off switch in Settings.
One log
Five apps' worth, on one log.
The coach can only decide because it sees all of it.
Instead of a logger
Sets, PRs, plate maths, rest timer, editable history — free and
uncapped.
Instead of a macro tracker
Meals, barcodes and targets that move with what you actually
trained and what your body actually burns.
Instead of a mobility app
A guided routine built from the muscles you loaded in the last
few days — not a library you have to shop in.
Instead of a running app
Your runs come in from your watch. A hard one is named in
tomorrow's readiness, so the squat day knows about it.
Instead of a coach app
The programme, the autoregulation and the form check — each one
showing the number behind it.
One honest exception: no GPS. Your watch
records the route. Antaeus reads the run.
How it works
One loop, closed.
-
01
Say the goal
Five questions. Or start a proven program as written.
-
02
Get the plan
A multi-week block with real sets, reps and loads.
-
03
Log the work
One hand, mid-set. Or tell Siri and keep lifting.
-
04
It adjusts
Rough week? Volume moves. Stalled lift? The cause gets named.
-
05
See it arrive
Strength, muscle coverage, and the reason behind each change.
What it does
Six things it takes off your plate.
The coach
It plans your training — and shows its work.
Every decision comes with the number behind it. You can disagree
with it, which is the point: nothing changes silently.
- Programs built from your goal, schedule, and the gear you actually have
- Stalled lift? It names the likely cause and changes one thing
Coach · Squat
Up 2.5 kg this week. Last top set moved fast at RPE 7.
Coach · Chest
Holding volume. Two short nights logged — we consolidate, not push.
Coach · Bench
Plateau broken — e1RM +4%. The deload did what it was for.
The logger
Log a set in seconds, one-handed.
Tonight's target, last time's numbers, then out of your way.
- Last week's numbers sit behind today's, so "same again" is zero typing
- Steppers sized for a tired hand, plus plate maths, rest timer and warmups
- Say "225 for 5 on bench" to Siri and it's logged
The map
See which muscles are actually on track.
Green is in range, amber is short, deeper green is past what you
need. It's a decision surface, not a badge.
- Sets per muscle per week, against a range that fits your experience
- Tap any muscle for what trained it, how fresh it is, and what to add
The fuel
Eating and training on one page.
Calories left with the training already counted in. Barcodes
are free, forever — no AI, no quota.
The proofPR
Watch strength arrive.
Bests, estimated maxes and the trend behind them. Named goals
with an honest date, or an honest "not enough data yet".
The tools
A form check, a sore shoulder, a question at 11pm.
Film a set: depth, bar path and tempo measured on your phone,
clip never uploaded. Something hurts? A triage that adapts the
plan and flags what needs a clinician.
Where your data lives
No account. No feed. No server of ours.
Logging works in a basement gym with no signal. Your log can't be
lost, sold, or fed to anyone's algorithm.
Sign-up
There isn't one. Open the app and lift.
Your log
A database on your phone. A full backup you can save anywhere.
Form videos
Analysed on-device. Never uploaded, never synced.
AI features
Send only what they need — numbers, or a photo you pick. Never your
form video. The specifics.
Leaving
Export the whole database, or delete the app. That's the exit.
