Wearable technology has become part of everyday life. Devices such as Apple Watch, Fitbit, Garmin, and other fitness trackers record heart rate, physical activity, sleep patterns, and movement throughout the day. While many people use these devices for health tracking, insurers are increasingly reviewing wearable data during claim investigations.
In some accidental death and life insurance claims, insurers now analyze wearable device data to reconstruct the final hours of the insured’s life. In 2026, this type of digital evidence is appearing more often in investigations involving disputed causes of death.
Attorney Christian Lassen represents beneficiaries nationwide in disputes involving denied life insurance claims.
What Wearable Devices Actually Record
Modern wearable devices collect a surprising amount of information. Depending on the device, the recorded data may include:
Heart rate measurements throughout the day
Steps and movement activity
Exercise sessions and workouts
Sleep patterns
Location and GPS activity
Irregular heart rhythm alerts
Many devices also store time stamped data that allows investigators to reconstruct activity during specific time periods.
Why Insurers Review Wearable Data
In accidental death claims, insurers often attempt to determine exactly what happened during the final moments before death. Wearable device data may provide clues about physical activity, heart rate changes, or sudden stops in movement.
Investigators sometimes analyze the data to determine:
When the insured stopped moving
Whether the insured experienced a sudden heart event
Whether the insured was physically active before the death
Whether the death occurred during exercise or recreational activity
Insurers may argue that the data contradicts the reported cause of death.
Claims Involving Disputed Accidents
Wearable data is often used in claims where the insurer questions whether the death was truly accidental.
For example:
A person is found after a fall and the claim is submitted under an AD&D policy. The insurer reviews wearable data and claims the heart rate pattern suggests a medical event occurred before the fall.
In another case:
A drowning is reported as accidental. The insurer analyzes wearable data and argues that physical activity patterns suggest the insured experienced a health episode before entering the water.
In these situations, insurers may attempt to argue that the death was caused by illness rather than accident.
Heart Rate Data and Medical Event Arguments
Heart rate monitoring is one of the most common features in wearable devices. Insurers sometimes review this data when investigating claims involving sudden deaths.
For example, investigators may look for:
Rapid spikes in heart rate
Irregular rhythm alerts
Sudden drops in heart activity
Periods where no data was recorded
If the insurer believes the pattern suggests a medical condition such as a heart attack or arrhythmia, it may argue that the death was caused by illness rather than an accident.
Activity Data and Risk Behavior Allegations
In some cases insurers analyze activity logs to determine whether the insured engaged in potentially risky behavior.
Examples may include:
High intensity exercise sessions
Mountain or trail activity
Swimming or water activity
Late night physical activity before death
Insurers may attempt to use this information to argue that the insured knowingly engaged in hazardous activity.
The Limitations of Wearable Data
Although wearable devices collect extensive data, the information has limitations. These devices are not medical diagnostic tools and are not designed to determine the cause of death.
Several issues may affect the reliability of wearable data:
Devices can lose contact with the skin
Heart rate readings may fluctuate due to sensor error
Data may stop recording when the device battery dies
Movement data may not reflect actual events accurately
Despite these limitations, insurers sometimes rely heavily on the data when analyzing claims.
Digital Evidence in Modern Claim Investigations
Wearable device data is part of a broader trend where insurers examine digital information when investigating life insurance claims.
Investigators may review:
Fitness tracker data
Smartphone activity logs
GPS location records
Smart home devices
Vehicle telematics
These sources can sometimes help reconstruct events, but they can also lead to disputes about how the data should be interpreted.
Legal Help With Claims Involving Wearable Device Data
Life insurance and accidental death claims that involve wearable device data can become complicated because insurers may attempt to interpret digital information in ways that affect coverage decisions.
The Lassen Law Firm focuses exclusively on life insurance disputes nationwide. Attorney Christian Lassen has more than 25 years of experience representing beneficiaries in denied life insurance claims.
If a life insurance or accidental death claim has been denied based on data from a wearable device or wellness app, legal review may help determine whether the insurer properly interpreted the evidence.
