Strength coaching for iPhone

Add weight the week you earn it.

No cloud AI decides what goes on your bar. Every weight and every set is calculated directly on your phone using your own training data. Jerry runs on your phone and coaches you: he adjusts your next set while you rest, locks in what he expects before you lift, and grades his own accuracy. When he is wrong, the misses count.

Ask to try it free See him change a set

In testing on iPhone, and free for testers. No waiting list: you write to a person, and a person writes back.

The OrderedStrength home screen after one logged workout. It says Building, meaning Jerry is still learning you; fatigue is 7 percent and recovery 66 percent, both marked Estimate; and the Consistency score is still empty.
The OrderedStrength home screen after a hundred logged workouts. It now says Individual, with a hundred workouts of this athlete's own evidence behind it; fatigue reads 18 percent and recovery 56 percent, both marked Your Data; and Consistency reads 54 percent.

What he actually does

He decides, then he reacts.

A plan hands you a program and stops listening. Jerry picks the lift and the weight, then changes the rest of the session the moment a set goes differently than he expected.

Two phones showing the workout screen. Behind: The workout screen before the first set of the athlete's 101st workout. For the Barbell Bench Press it asks for 3 sets of 6 to 10 reps, stopping with 2 reps to spare, the first at 72.5 kg for 8 reps. It lists three warm-up sets and the plates for each side, and notes that last Sunday was 2 sets of 8 reps at 70 kg with 1 rep to spare, and that today is 2.5 kg heavier because the anterior deltoid is fully recovered. In front: The same workout screen after the athlete confirmed the first set as 8 reps with 4 more still in the tank. A line reads Next Set Raised, the next set is 75 kg for 8 reps, and Jerry explains that 4 reps to spare earns a step, so the next set goes up one step. The rest timer reads Rest Complete.
Before set 1 he asks for 72.5 kg for 8 reps, stopping 2 reps short of failure. You do 8 and could have done 4 more, so he answers “That earns a step. The next set goes up one step.” and raises the next set to 75 kg · 8 reps · RIR 2.
The plate goes on when your reps say soWhen you reach the top of your rep range at the effort he asked for, the weight goes up.
You finish what you startHe cuts a set today so you still have something left on Thursday. Your energy goes where it pays off.
You keep training when something hurtsTell him. He removes what is unsafe, keeps everything else at full effort, and brings the movement back in steps you can see.

Your body, muscle by muscle

See which muscles still need rest.

Every muscle is colored by the recovery it still needs, worked out from your sets. Teal is fresh, yellow needs some rest, orange and red need more. Turn the body with a finger and tap a muscle for its detail.

Recorded on Jeremiah's own phone, played at twice the speed.

I am Jeremiah, and I built this. Jerry, the coach inside it, carries my name.

Every app promises to personalize your training from the first session, as though it had met you. On day one it has only your age, your sex, and your bodyweight: an average for people like you, wearing your name. Every coaching app I paid for was certain about me on day one, and not one ever told me it had been wrong. So this one writes its guess down before you lift and grades itself where you can read it.

Behind it is me and a group of testers, not a company with a support desk. If you write to jeremiah@orderedstrength.com, I am who answers.

Testing on iPhone now

Want it on your phone this week?

I am looking for athletes to train with it and tell me what breaks.

You get the whole app, freeEverything, for as long as it is in testing. No watch needed, and your history from Strong or Hevy comes with you.
You train your normal weekYour gym, your equipment, your days, in kilograms or pounds. He plans around the days you train.
You tell me the truth, good or badWhat breaks, what confuses you, and after each set, how many more reps you could have done.
Message me on WhatsApp Email me instead

I read every message myself. If the app fits how you train, I send you a TestFlight invitation, Apple's free app for trying apps before they come out, and you install it in a few minutes. If it does not fit yet, I will tell you.

Where other apps stop

Four kinds of app, and where each one stops.

None of them changes the set you are about to do.

A logbook
Records your sets beautifully. Decides nothing.
A plan
Adapts between sessions. Not during one.
A wearable
Scores your recovery. Never writes your workout.
A chatbot
Ask twice, get two answers. Nothing to hold it to next month.
Jerry
Decides your set, changes it while you train, remembers you for months, and keeps score on himself where you can read it.

Already have a coach?

Keep your coach. Give them Jerry's report.

In Profile, one tap makes a PDF on your phone that you can send to your coach. It is free, whether or not you pay.

What you didYour sessions from the last 28 days, with how many more reps you could have done, each time you typed that number.
Where you standYour estimated max on each lift, and last week's hard sets for each muscle.
How Jerry didHow often his predictions about you were right or wrong, and any injury with the days left until full load.

Day one against day one hundred

On day one, he tells you he does not know you yet.

On day one he knows only what you told him: your sex, age, experience and bodyweight. That gives him an average for people like you. If you bring your history from Strong or Hevy, he starts from your recent lifts instead, but he learns you only from the sets he watches you log. Drag the slider: only one of these two ever changes.

A typical coaching app

Your one rep max is 137 kg.

It shows no source, states no certainty and gives you no way to check it.

unchanged since day one

Jerry

I do not know you yet. Until your own sets exist I start from averages for people like you, matched on what I actually know about you, and I say so every time I do.

Based on: published research averages. Nothing here is a claim about your body. It becomes one only when your own sets say so.

Averages

0

This box is an example, not a screenshot: the app says Building, not a percentage. A web page can only count sessions. In the app, each lift moves onto your own numbers as you log it, and the home screen says Individual only after at least 30 workouts across at least eight different weeks, plus a few more checks. He trusts his own numbers less when his predictions miss. Details on how it works.

The seal

Try to make him look better than he was.

Any app can claim after your set that it knew. Jerry seals his prediction before you touch the bar, like a letter in an envelope. Change any detail and the seal breaks. Try it: widen his range, or change the lift.

For the technically curious: exactly what is sealed

These are the exact fields the app seals, in the exact form it seals them, which is why the seal above can be checked at all. The seal is their SHA-256 fingerprint, worked out together with a random number, the nonce, so that nobody can guess it in advance. The weights are written as whole numbers so that no rounding can creep in: 1025000 is 102.5 kg. The last line is the date, counted in seconds since 1 January 1970.

Nothing you change here leaves your device. The check ran right here, on your own phone or computer.

Separately, our own server checks the original sample seal, never your edits, so you can see that our server and your device agree.

His forecasts for a session, a set, a goal date and the month ahead are all sealed this way. Every night we join the day's seals into one code and post it in public: a postmark that proves each prediction existed that day. See every day posted so far.

The pressure test

Three things most apps never show you.

The same screen on day one and after a hundred workouts, and the page where Jerry checks his own predictions. Real screenshots, nothing retouched.

The home screen after one logged workout. Fatigue reads 7 percent and recovery 66 percent, both labelled Estimate, the Consistency score is still empty, and the best lift on record is a Barbell Back Squat at an estimated max of 60.9 kilograms.
On day one. The screen says Building. Fatigue 7% and recovery 66% are marked (Estimate): averages for people like you, until your reports of how sore you feel replace them. Consistency is empty: one workout is not enough to measure it. And in the app's own words, what he can tell you opens on evidence, not on time.
The same screen after one hundred logged workouts. It now says Individual, fatigue and recovery read 18 and 56 percent labelled Your Data, Consistency reads 54 percent, and the best lift on record is a Barbell Back Squat at an estimated max of 139.8 kg.
After a hundred workouts. The screen says Individual, and fatigue and recovery read (Your Data), which happens once you have told him often enough how sore you feel. Consistency, 54%, is how steadily you report how many more reps you could have done on each set, not how well he knows you.
The app's detailed view, on its Patterns page. My Track Record says 75 percent of the predictions Jerry checked landed in the range he gave and is marked Individual; What I Have Confirmed reads 4 of 6 and Fitness Age 25 years, both still marked Observing.
How he checks himself. The Patterns page opens with My Track Record: 75% of the predictions Jerry checked for this athlete landed inside the range he gave, and what he has not confirmed yet still says Observing. Yours are checked the same way. Athletes who publish theirs are on the record.

All three screenshots are of the same athlete, captured from the app as it ships.

Is it for you?

Who it is for, and who it is not for.

Better to read this now than to find out in week three.

It is for you if

  • You lift at least three days a week and plan to keep going for months
  • You want to know what weight to put on the bar, set by set
  • You want a coach who tells you when he is guessing
  • Something hurts and you want to keep training without loading the part that hurts

It is not for you if

  • You only want a log to look at. The logbook is free, but the reason to be here is a coach who tells you what to lift
  • You mainly want to run or take classes. Jerry is a strength coach
  • You plan to stop after two weeks. Jerry needs at least 30 workouts across at least eight weeks to really know you

What it costs

Free while it is in testing. Logging and the daily readings stay free after that.

Testers get everything today. When it reaches the App Store, Jerry coaches every new athlete in full for 28 days, with no card. After that, these are the prices, written down now so you can hold us to them.

Free, and it stays free

Every day, whether or not you pay

  • Log every set, and build your own sessions
  • Your fatigue, recovery and readiness, every morning
  • Every session you have ever logged
  • Every warning: a stalled lift, a week that must be lighter, a body that cannot take what you planned. Pro tells you what to do about it
  • His scorecard on you: how many of his predictions about your strength landed inside the range he gave, misses counted
  • His voice in the gym after your sets: what the set showed, and when to back off

Pro. Jerry coaches you.

The first 28 days are on us

  • His prescribed sessions, built for your body: the lifts, the weight on the bar and the warm-up. He changes them while you train
  • After every session, what it cost you and what changes next week
  • Ask him anything, like what a heavier week or a different lift would do to you
  • Let your Apple Watch or AirPods read your sets: reps and bar speed. He checks each device against what you log before he trusts it
  • Everything he has learned about your body, your six-week forecast, your records
  • At day 28, his summary of your first four weeks: what he built, what he learned, and his scorecard on you
