Choose rPPG When...
- ✓Deploying to many users without device logistics
- ✓Users don't own or won't wear devices
- ✓Periodic health checks, not continuous monitoring
- ✓Telehealth integration is needed
- ✓Zero-friction onboarding is critical
- ✓Budget doesn't allow per-user device costs
Choose Wearables When...
- ✓Continuous 24/7 monitoring is essential
- ✓During-workout heart rate tracking needed
- ✓Sleep tracking is a key requirement
- ✓Step counting and activity logging required
- ✓Small user group willing to wear devices
- ✓Budget supports device costs and support
Comparison FAQ
Common questions about rPPG vs wearables
Is rPPG as accurate as Apple Watch or Fitbit?
For resting heart rate, our rPPG technology achieves comparable results to consumer wearables. During exercise, wearables with optical sensors maintain better performance due to continuous skin contact. rPPG is best suited for stationary measurements.
Can rPPG replace my fitness tracker?
For certain use cases like morning HRV checks, stress assessments, and periodic health monitoring - yes. For continuous activity tracking, step counting, sleep monitoring, and during-workout heart rate, you'll still benefit from a wearable.
Why would I use rPPG if I already have a wearable?
rPPG is ideal for organizations deploying health monitoring at scale (no devices to ship/support), for users who don't want to wear devices, and for adding vitals to telehealth without patient equipment. They serve complementary purposes.
What about blood oxygen (SpO2)?
Both rPPG and wearables estimate SpO2 using similar optical principles. Both provide valuable trending data for remote monitoring and telehealth applications.
