The watch has been counting all along.
Heart rate, movement, sleep and VO2max, next to your food and your labs.
File import, not a live connection. Apple Health hands you your own history as a zip, and Ojava works from the watch records inside it.
- Heart rate
- HRV
- Activity rings
- Sleep
- VO2max
What crosses over
Five signals,none of them alone
The watch is very good at the hour you are in. It is not built to hold the meal you logged at lunch, the panel you had drawn in July, or the visit summary sitting in a portal. Ojava keeps those in one record and reads them together.
Example screen, with illustrative values.
Heart rate and resting heart rate
Every sample the watch took, gathered into a resting baseline that a hard block of training or a short week visibly bends.
Heart rate variability
Your own seven-day line rather than a population average, so a low morning reads as low for you.
Activity rings and move goal
Move, exercise and stand, read against the goal you actually set and the week you actually had.
Sleep
Duration, the stages the watch recorded, and how steady your bedtime has been across the month.
Blood oxygen
Overnight readings kept as trend context beside sleep and heart rate, never interpreted on their own.
VO2max
The watch estimate preserved as it came, plus the fitness age Ojava computes from it, so you can watch the pair move together.
How it arrives
Three steps,then it is quiet
Setup is a file, not a project. Nothing joins your record until you accept it, and anything the reader got wrong can be corrected by hand first.
Export it once
Ask the app for your own history and drop the file in. The type is read from the file itself, and each type has its own parser rather than one hopeful reader for everything.

Values are checked back against the source, and readings that overlap with another device are collapsed rather than counted twice. The result sits in review until you accept it.

Sleep debt, readiness and training load are derived in code, the same way each time. The coach reads those finished values. It never redoes the arithmetic, and it says what is missing instead of filling the gap in.

A recovery number on its own is a number. Read next to what you ate, what you trained and what your last panel said, it starts to explain itself.

- Labs
- Wearable
- Records
Example screen, with illustrative values.
The Health app on its own
- Three rings a day, and a lot of charts under them.
- No idea what you ate before the workout.
- No lab result anywhere near the heart rate line.
- Records live in a portal the watch cannot see.
In Ojava, beside everything else
- Rings and training load beside the meals that fuelled them.
- Fourteen days of resting heart rate under a July lipid panel.
- Sleep debt and readiness computed from one deduplicated store.
- A coach you can text that reads those finished numbers.
File import, and a wellness read.
Ojava works from your own Apple Watch export as patient-owned wellness context, and keeps it there. It explains, trends, organizes, and helps you prepare for a visit.
- Not continuous monitoring, and not a medical device.
- No diagnosis, no prescription, no dose, no lab order.
- No clinical alert, and no replacement for your clinician.
The real questions
Does Ojava talk to my watch directly?
Does Ojava talk to my watch directly?
Not today. Ojava works from the Apple Health export you download yourself. A signed-app HealthKit path is built and stays gated until store and real-device verification is complete, and nothing here claims a live sync before there is one.
The watch and my phone both counted that walk. Which one wins?
The watch and my phone both counted that walk. Which one wins?
One of them, and only one. Overlapping readings from two devices are collapsed before anything is stored, so a walk is never counted twice in training load or in your own baseline.
Is any of this medical monitoring?
Is any of this medical monitoring?
No. Ojava treats the watch as a consumer wellness device. Readings become trend context and material for a conversation with your own clinician. They are not clinical alerts, and Ojava does not diagnose, prescribe, dose, or order labs.
How often should I export again?
How often should I export again?
Whenever you want the trend to be current, which for most people is monthly. Ojava shows how old the newest reading is, so a stale line is visible rather than quietly assumed to be fresh.
Sources
What this page stands on.
Consumer wearable readings are useful trend context, not clinical measurements. These are the papers and official sources that set that boundary.
Reliability and Validity of Commercially Available Wearable Devices for Measuring Steps, Energy Expenditure, and Heart Rate
Fuller, Colwell, Low, et al., 2020
Supports treating consumer wearable data as useful trend context with device and metric limitations. It does not validate wearable data as a standalone medical finding.
Patient Generated Health Data Use in Clinical Practice
Cohen, Keller, Hayes, et al., 2019
Supports auditing whether patient-generated data have provenance and clinical-use context before treating them as useful care context. It does not validate Ojava as a diagnostic system.
Recommended Amount of Sleep for a Healthy Adult
American Academy of Sleep Medicine and Sleep Research Society, 2015
Supports adult sleep-duration education. The tool does not diagnose sleep disorders or validate a specific wearable score.

Nights and labs,one record
Export Apple Watch once, accept what the reader found, and the trend sits beside your food, your training and your last panel from then on.
You accept it first
Every reading waits in review. Nothing joins your record until you say so, and a wrong value can be fixed by hand.
Computed the same way each time
Readiness, sleep debt and training load are derived in code. The coach reads those finished numbers rather than inventing its own.
Yours to take back
Export or delete what you brought in whenever you decide it should leave. No ad targeting, and no model training on your health records.
Ojava is a General Wellness product. It organizes and explains your own data and helps you prepare for a visit. It does not diagnose, prescribe, dose, order labs, or replace your clinician.
