What If Your Smartwatch Proves You Were Injured—Can You Use It in a Personal Injury Case?

June 02, 2025

In today’s tech-driven world, your smartwatch can do more than track steps or monitor your heart rate—it might also play a pivotal role in your personal injury case. That’s right: if your smartwatch proves you were injured, you might be able to use it as evidence to support your claim. But how does this work in practice? What are the legal hurdles? Let’s break it down.

In recent years, wearable devices have played a surprising role in legal matters—from proving someone was active to establishing a timeline of events after a serious incident. For personal injury claims, they offer a unique way to support traditional evidence with data that comes straight from your wrist.

Can Smartwatch Data Really Be Used in a Personal Injury Case?

The short answer: yes, but it depends. Smartwatches like the Apple Watch, Fitbit, and Garmin devices collect massive amounts of biometric data. This can include heart rate changes, sleep disruptions, physical activity levels, and even blood oxygen saturation. When you’ve been hurt in an accident—whether it’s a car crash, slip and fall, or another injury—these changes can offer a digital trail of how your body responded to the trauma.

For example, if your device logs a sudden drop in physical activity following an accident, that can serve as supportive evidence of a change in your health status. Similarly, if your resting heart rate increases after a traumatic event, it may reflect ongoing stress or injury recovery.

Real-World Example

Consider someone who jogged every morning, with their smartwatch consistently logging each run—until the day of the accident, when the activity suddenly stops. Or imagine a spike in heart rate during the crash, followed by weeks of restless sleep data. These patterns can help support claims of both physical and emotional distress.

How Smartwatch Data Supports a Personal Injury Claim

Courts and insurers rely on credible, consistent evidence. While smartwatch data isn’t a replacement for medical records, it can back up what you tell your doctor—and what your doctor puts in your file. Here’s how smartwatch data can support your case:

  • Tracking a noticeable drop in activity levels post-injury
  • Demonstrating changes in heart rate related to stress or trauma
  • Showing interruptions in sleep linked to pain or anxiety
  • Comparing pre-accident and post-accident health patterns
  • Establishing a timeline of when the injury occurred

Is Smartwatch Data Admissible in Court?

In many personal injury cases, the use of smartwatch data is still a relatively new concept—but courts are starting to accept it when it's relevant and reliable. Like any evidence, it must meet standards for admissibility. This often involves authentication (proving the data belongs to you) and demonstrating that it’s been stored without tampering.

It’s also worth noting that as wearable technology becomes more common, courts are growing more familiar with this type of digital evidence. Still, success often depends on how well your attorney presents and explains the data in context.

The Role of Expert Witnesses

Sometimes, personal injury attorneys will bring in tech or medical experts to help interpret the smartwatch data. These experts can explain to a judge or jury what the numbers mean, and how they correlate with your reported symptoms or injuries.

How to Preserve and Share Smartwatch Data for Your Case

If you believe your smartwatch holds helpful evidence, don’t wait—preserve the data. Accident-related data can disappear if your device resets or overwrites older information. Talk to your attorney about how to back up and share this data properly.

Tips for Using Smartwatch Data as Evidence

  • Download and save all health and activity logs after the incident
  • Don’t alter or delete any data, even if it seems unimportant
  • Keep the device synced with your smartphone or cloud storage
  • Share the full timeline—not just isolated metrics
  • Let your attorney review everything before handing it to insurers

Should You Rely Only on Your Smartwatch to Prove Your Injury?

Not at all. While smartwatches offer compelling support, they should never replace traditional forms of evidence. Always seek medical treatment, follow through on appointments, and document your recovery with care. Your smartwatch data is just one piece of a larger puzzle.

At van der Veen, Hartshorn, Levin & Lindheim, we stay on top of emerging trends in personal injury law—including the growing role of digital health data. From investigating your injuries to building a strong case, we know how to incorporate new forms of evidence in ways that resonate with judges and juries. We understand how to use smartwatch data to reinforce your medical records and illustrate how the accident affected your quality of life.

What Types of Injuries Can Smartwatch Data Help Prove?

While smartwatch data won’t diagnose an injury, it can highlight symptoms that point to certain conditions. For example, consistent low activity and sleep disruption may support claims of chronic pain or traumatic brain injury. An elevated heart rate could correlate with stress-related disorders, anxiety, or internal injury.

Some common injuries where smartwatch data may be useful include:

  • Whiplash and soft tissue injuries
  • Post-traumatic stress disorder (PTSD)
  • Concussion or mild traumatic brain injury (TBI)
  • Back and spinal cord injuries
  • Chronic pain or fatigue syndromes following an accident
