ChatGPT
BRAND (4)
SUMMARY
ChatGPT provides a comprehensive analysis of wearable health tech accuracy across major brands. Apple Watch leads in heart rate monitoring (1-7% error) but overestimates energy expenditure by ~28%. Fitbit shows variable accuracy with 2.4-17% heart rate error and tends to underestimate steps. Garmin achieves ±3% heart rate accuracy 49% of the time but underestimates energy expenditure 69% of the time. Oura Ring excels in sleep tracking accuracy. The analysis emphasizes that accuracy varies significantly by device and metric, recommending clinical-grade equipment for critical health monitoring.

Perplexity
BRAND (2)
SUMMARY
Perplexity offers a metric-focused comparison with specific accuracy data. Fitbit Charge devices excel in step counting with <25% error rates. Apple Watch achieves <10% heart rate error in studies but shows limitations in clinical settings. Most wearables struggle with energy expenditure (>30% error). The analysis reveals heart rate errors up to 20% and calorie estimation errors up to 100%. Emerging applications in disease detection show promise, with wearables demonstrating potential for atrial fibrillation and COVID-19 detection.
Google AIO
BRAND (5)
SUMMARY
Google AIO presents a balanced overview of wearable accuracy limitations and factors affecting performance. Heart rate and blood oxygen show good accuracy, while energy expenditure and sleep stage detection remain challenging. Step counting typically underestimates by 9-12%. The response highlights how device type, user characteristics, and activity levels influence accuracy. Specific brand mentions include Fitbit for sleep tracking, Apple Watch for user experience, Oura Ring for sleep accuracy, Garmin for overall accuracy, and Polar H10 for heart rate precision.
