Coaching that already knows the week.
Load, sleep and food, read together before it says anything.
Ojava is a general wellness product. It coaches training, recovery and food, and it does not diagnose, prescribe, dose, or clear you for exercise.

WHY IT LANDS
It reads the week,then it speaks
A generic plan does not know you slept badly twice and trained hard on Tuesday. This one starts from four signals it already holds, says what it saw, and then makes the call, so you can disagree with the reasoning rather than the tone.
- Recovery this week
- 62 of 100
- Training load
- 412, line 386
- Sleep debt carried
- 1.2 h

Example screen, with illustrative values.
- It shows the reason
Every suggestion arrives with the numbers it came from, so nothing reads as an oracle.
- It uses your own line
Load is measured against your own rolling four week average, never against a population or a leaderboard.
- It stays wellness-only
Training, recovery, sleep and food. Never a diagnosis, never a prescription, never a clearance to exercise.
THE BOUNDARY
A coach,not a clinician
What Ojava does
- Suggest a session for today from load, recovery, sleep and the time you have
- Show the numbers behind every suggestion
- Track sessions, weigh-ins, food and the week against your own line
- Say plainly when something looks worth a professional look
- Export or delete everything, at any point
What stays with a clinician
- Clearing you to train, or declaring an activity safe for you
- Diagnosing an injury, or naming what a pain is
- Prescribing, dosing, or managing a medication
- Rehabilitation after an injury or a procedure
- Anything sudden, severe, or getting worse
Ojava is a general wellness product. If something hurts, changes suddenly, or worries you, stop and speak to a clinician rather than to a coach.
HOW IT WORKS
Three inputs,and one honest answer
The work is already happening on your wrist and on your plate. The coach simply reads it before it opens its mouth.
The week arrives on its own
Sessions from the watch or by hand, nights from the phone, meals from a photograph or a sentence. Nothing here asks you to fill in a form.
412Slightly above your own line, with one rest day taken.
The numbers are computed, then read
Load, recovery and sleep debt are derived in code, the same way each time. The coach reads those finished values rather than estimating around them, and it says what is missing instead of inventing it.
- Recovery
- 62 of 100
- Sleep debt
- 1.2 h
- Week load
- 412
Then it makes the call, with its reasoning attached
One suggestion for today, the four numbers behind it, and the freedom to ignore it. Ask why in the same thread and it answers with your own figures.
- what should I do today
- Easy 40 minutes. Load is 412 against your 386 line and you are carrying 1.2h of sleep debt.
Every suggestion is a suggestion. Nothing here clears you to train or tells you an activity is safe.
THE FOUR SIGNALS
What it works from,before it answers
- 01
Recovery
How the week has actually gone, from the nights and the sessions you logged.
- 02
Training load
412This week against your own rolling four week line, never against anybody else.
- 03
Sleep debt
- Last night
- 6h 04m
- Debt carried in
- 1.2 h
What the short nights added up to, carried forward rather than quietly forgotten.
- 04
Time available
- Today
- 40 min
The session it suggests fits the window you actually have, not an ideal one.
QUESTIONS
The awkward ones,answered first
A coach that will not clear you to train needs to be clear about what it does instead.
Is this a replacement for a human trainer?
No, and it does not pretend to be. It is daily coaching built on numbers you already generate, available at the moment you are deciding what to do. A human coach watching you move sees things no app can.
Can it tell me whether it is safe to train today?
No. It can tell you what your load, recovery and sleep debt look like and what it would suggest given them. Whether an activity is safe for you is a clinical judgment, and it belongs to a clinician.
What if I am injured?
Stop and speak to a clinician. Ojava does not diagnose an injury, name what a pain is, or run a rehabilitation plan, and it will say so rather than guessing.
Does it need a wearable?
It is better with one, because recovery and sleep are what make the suggestion specific. Without a device it still reads your logged sessions, your food and your own weekly line.
Does the coach make numbers up?
It is not allowed to. Load, recovery and sleep debt are computed in code first. The model reads those finished values and puts them into words, and where a value is missing it says so.
