Mike’s Quick Answer
Fitness-tracker data can help or hurt a personal injury case, but it rarely speaks for itself. A watch or app may record steps, workouts, heart rate, sleep estimates, location, or periods when the device was not worn. A meaningful change from the person’s pre-accident baseline may support an activity-loss claim. The same data may be used to argue that the person remained active. Neither conclusion is automatic. Consumer wearables are not medical instruments, step counts do not measure pain, and a recorded activity does not show how it felt or what happened afterward.
A Baseline Makes the Numbers More Useful
Five thousand steps on one day means little without context. The same number may be normal for one person and a major reduction for another. Data from before and after the accident can show whether activity, exercise, sleep, or routine changed.
The comparison period should be fair. Weather, work schedule, illness, vacations, device upgrades, and whether the tracker was consistently worn can explain apparent changes unrelated to the injury.
Recorded Activity Is Not the Same as Physical Ability
A person may walk through pain because a child needs care or a job cannot be missed. A tracker may count arm movement as steps, miss stationary cycling, or record a car ride as activity. It usually cannot show medication, limping, rest breaks, or symptoms later that day.
Heart-rate and sleep features use consumer algorithms and estimates. They can provide leads, but a doctor should decide whether any health conclusion is medically meaningful.
Preserve the Account Without Curating It
Do not delete unfavorable days, change historical entries, or begin wearing a device solely to manufacture proof. Preserve account access, device information, settings, and a supported export when the data is genuinely relevant.
Screenshots are useful for review but may omit raw fields and context. An export or forensic collection can be considered if the activity dispute is important enough to justify the cost and privacy intrusion.
Discovery Should Match the Claim
A defense request for years of heart rate, sleep, location, and reproductive-health information may reach far beyond a limited orthopedic claim. Relevance and proportionality still apply even when data exists in an app.
I first decide whether the tracker actually bears on a disputed issue. If it does, I use it with testimony, calendars, work records, and medical evidence. The device is one witness, not a verdict on the person’s condition.
Frequently Asked Questions
Can step counts prove that I am not injured?
No. They may show recorded movement, but not pain, mechanics, limits, necessity, or the effect afterward. Context and medical evidence matter.
Must I give the defense my entire fitness account?
Not automatically. A discovery request should be relevant and proportional. Scope, time period, privacy, and the claims actually made can be addressed.
Should I start wearing a tracker after the accident?
Do not create a self-monitoring program for litigation without advice. Existing habits are usually more reliable than activity produced for a lawsuit.
