Stratum Metrics High Bay: this week’s schedule rail, the workout in progress and today’s plan from two Directors
Stratum Metrics workout in progress: Safety Bar Squat sets logged against last time, Romanian Deadlift up next, with Type, the gold mic and Finish below

Never guessesA missed number is a question, not an invention.

Your phone, your dataWorkouts live on your device. No ads, never sold.

True Volume IsolationPrimary barbell mechanics, accessory circuits and conditioning live in distinct telemetry lanes. PRs remain clean.

Solo or coachedTrain on your own, or follow plans from your Director.

Engine benchmark // Zero-cloud parser

Say it naturally. Stratum Metrics logs it.

No rigid commands. Speak the way you talk to a training partner.

The parser runs on your phone, with no cloud. When a number or a name is missing, it asks instead of guessing. These are real results from the app’s engine.

“Bench 225 for 5, same weight, got 7”
Barbell Bench Press225 lb × 5 · 225 lb × 7
“8 raps at 185 on incline bench”
Incline Barbell Bench Press185 lb × 8 · “raps” read as reps
“Squats 225, three sets”
Which squat? Back, front, hack…3 sets at 225 lb · reps asked, never guessed
“Deficit RDL 3 sets of 8 at 185”
Deficit Romanian Deadlift3 × 8 at 185 lb · its own lift, never merged with the plain RDL
“Ran 2 miles in 18 minutes”
Run2 mi · 18 min · 9:00 /mi
How it works

Built for the gym floor, not the desk.

Most logs fail between sets: chalky hands, a timer running, plans buried in texts and printouts. Stratum Metrics takes your training the way it actually happens.

Stratum Metrics High Bay with no workout yet, and the gold mic in the middle of the tab bar
01 · Voice

Talk between sets. Don’t type.

Press the gold mic on the phone and try it. In the gym you say it the way you’d tell a training partner. Stratum Metrics turns it into the right exercise, weight and reps, set by set.

  • Gym talk works: “two twenty-five for five”, “thirties for twelve”, “same weight, got seven”.
  • Strength, accessory work and cardio land in the right place, in the order you said them.
  • Your music keeps playing. It only pauses while the mic is listening.
Stratum Metrics asks which squat and how many reps instead of guessing
02 · Trust

It asks. It never guesses.

Missed a number or said something it can’t be sure of? The card shows a question instead of inventing an answer. Nothing saves until you tap Save.

  • Missing reps show as “?”, never a made-up number.
  • Unclear names become choices: “Squats” could be back, front or hack.
  • A new variant like “deadlift with chains” asks first; it never logs as the plain lift.

03 · Session

Last time is already there.

Today’s plan and your last numbers wait in Session in Progress. Tap a set to log it as is, or say what changed.

  • Sets are numbered across the whole workout, newest card on top.
  • Supersets are bracketed together, and drop sets sit under their top set.
  • A chest press at one gym isn’t the same as the chest press at another. Machines and cables are tracked per gym, so your progress on each one is real.

04 · Import

Coach texted the plan? Paste it. On paper? Scan it.

Paste a workout from a message, an email or a note, or scan a printed page. Stratum Metrics sorts it into exercises, sets, reps and weights, and keeps supersets together.

  • Shorthand like RDL, DB and “3x8-10” just works.
  • Anything it isn’t sure of asks, like the voice card.
  • The scan is read on your phone and never leaves it.

05 · Your Director

Your coach plans it. You show what you really did.

A trainer, coach or Directing Team assigns the plan in Stratum Metrics, and it appears as Today’s Plan in the High Bay. Log as you go, or tap “Completed as planned” when you did it exactly.

  • Reports show planned against done, set by set.
  • Director-assigned work counts toward the plan it came from.
  • Sharing starts off. You choose what your Director can see.

06 · Progress

Numbers you can trust.

Every exercise keeps its own record, so a PR on incline dumbbell press never pads your flat bench. Weekly volume rolls up by movement.

  • Numbers that look off for you are flagged before they count.
  • Warm-ups and prehab stay out of PRs and training volume.
  • Your PR history is kept, even when you fix a set later.
  • Machine numbers stay with the gym they came from, so a lighter stack across town never looks like a lost PR.

07 · Handoff

Partner training app: Directive.

If you have both apps, tap Save Workout and you’re done. Stratum Metrics commits the session to Directive’s App Group vault on your phone, and Directive picks it up on its own. No export, no app switching, no cloud in between.

  • A two-second note confirms the handoff. You’re never sent to another app.
  • If Directive is closed, the workout waits in the vault until Directive takes it.
  • Prehab and joint work are never handed over. Without Directive, nothing changes.

Better with Directive

Stop guessing.
Personalized fueling for your exact workout.

Stratum Metrics captures the mechanical work. Directive engineers the recovery.

Don't Just Track the Work. Feed It.

Hands your workouts to Directive, on your phone.

Heavy volume load and hard intervals shouldn't end in a spreadsheet. Finish a workout in the High Bay, tap Save Workout, and Stratum Metrics hands the totals to Directive on your phone. No double entry and no cloud in between. Directive works out the fuel, and harder-than-usual weeks earn extra.

Ground-Truth Loading

Direct capture of mechanical work, set by set, plus optical heart-rate telemetry from your watch or armband.

Zero-Cloud Handoff

Instant, private on-device handoff via Apple App Group IPC. No server round-trips.

Predictive Glycogen Math

Directive calculates fueling and replenishment windows from training strain, not step counts.

Wearables & Watches Alone

Inferred Calorie Estimation

  • Infers strain strictly from pulse and wrist movement
  • Subject to cadence locks and grip-squeeze dropouts
  • Can't see mechanical load: the weight, sets and reps you moved
  • Offloads generic static calorie burn targets
Stratum Metrics + Directive Ecosystem

Drive Your Best Performance

  • Measures true mechanical load and work volume
  • Uses data from your wearables and health apps to sharpen your telemetry
  • Distinguishes neuromuscular and high-glycolytic strain from low-cost aerobic base
  • Dynamically shifts peri-workout fueling around the sessions you actually did

The training that matters

Stratum Metrics sends your session length, effort, hard sets and cardio zones. Directive uses them to read your day.

Data integrity

Prehab and joint work you keep in its own lane never inflates your volume load, earns PRs or adds calories, in either app.

Stratum Metrics stands on its own

No Directive or account needed. Stratum Metrics computes no nutrition; Directive is the only calorie calculator.

One sign-in for both

One Directive LLC sign-in works in both apps. Your workouts still move only when you send them.

Lifting while cutting

Keep your training fueled without giving up your deficit.

Training for longevity, managing weight

Accessory and joint work stays in its own lane while training and fuel stay honest.

Training long or mixed

Cycling, running, hybrid racing: fuel the long sessions and the harder-than-usual weeks.

Nothing moves between the apps unless you send it or turn the connection on, and we never sell your data.

FAQ

Questions, answered.

When can I get Stratum Metrics?

Stratum Metrics is coming to iPhone and Android. Leave your email below and we’ll tell you once, the day it’s in the App Store and Google Play.

What does it cost?

Stratum Metrics is free at launch.

Do I need an account, or Directive?

No. Stratum Metrics works on its own with no account. Signing in with Apple or Google is optional, and connecting Directive is optional too.

Where is my data stored?

On your phone. Your workouts, notes and check-ins aren’t uploaded to our servers, we don’t run ads, and we never sell your data. Data leaves your phone only when you send a report, a backup or a workout yourself, or turn on a connection.

What if it mishears me?

You see a card with everything it heard before anything is saved. Anything it isn’t sure of is a question or a choice, never a guess, and you can fix any set with a tap.

Can my trainer or coach use it with me?

Yes. A Director (a trainer, coach or Directing Team) can assign plans and movement boundaries, and you log against them. You choose what they can see; every kind of sharing starts off.

Does prehab or joint work count toward my PRs?

No. Work you put in its own lane stays out of PRs, volume load and training volume. You can move an exercise between lanes later if you logged it in the wrong one.
