Editors’ Review
AFib monitor, developed by Andrius Sološenko, is a Wear OS app for continuous screening of Atrial Fibrillation using smartwatch optical sensors. It analyzes photoplethysmogram signals to flag suspected irregular rhythms and provides historical logs plus vibration notifications. The tool targets adult Wear OS smartwatch users seeking non-invasive rhythm awareness and trend data to inform conversations with healthcare professionals.
Can the app serve as a personal AFib screening aid?
The app is positioned as a screening and wellness aid that helps users collect long-term rhythm information from their watch sensor. It aggregates episode timestamps so a person can observe trends over days or weeks, supporting self-awareness of irregular rhythms rather than formal diagnosis. This use-case suits adults who want ongoing monitoring to share pattern evidence with a clinician.
How does the app reduce false detections from noisy signals?
The detection pipeline combines an automated rhythm algorithm with signal quality checks to lower false alerts caused by motion or poor contact. On devices that expose raw data the app can run a Raw PPG mode, bypassing firmware heart-rate smoothing for direct analysis. Those two elements address the practical challenge of separating artifact from suspected arrhythmia in wrist-based PPG recordings.
Is it appropriate for typical Wear OS owners and who benefits most?
The app requires a Wear OS watch with a functioning optical sensor, so compatibility drives suitability; performance is best on devices that allow raw PPG access. It targets adult users focused on proactive heart-health tracking rather than clinicians. No specialist training is required to run continuous monitoring, making it accessible to self-learners who want longitudinal rhythm insight from everyday wear.
How does the app communicate suspected events and preserve records?
When the algorithm marks a suspected episode the app records the event in a historical log and plots heart-rate data over time for later review. Vibration patterns notify users at episode start and end (three pulses at start, two at end). A built-in demo mode simulates signal input for previews, and monitoring automatically suspends when battery level falls below 15 percent to conserve device power.
Pros
- Continuous PPG-based rhythm screening from smartwatch optical sensors
- Integrated signal quality checks to reduce motion-related false alarms
- Raw PPG mode available on compatible devices for direct signal analysis
- Vibration alerts plus historical logs for trend review and clinician discussions
Cons
- Not a certified medical device, not for clinical diagnosis
- Raw PPG features depend on device hardware and firmware access
- Monitoring auto-suspends when battery drops below 15 percent
- Requires a Wear OS watch with a functioning optical sensor
Bottom Line
Practical, research-grounded screening for informed self-monitoring
AFib monitor is a practical option for adult Wear OS users who want ongoing, non-clinical rhythm screening. The developer’s role as a Senior Researcher at the Biosignal Analytics Laboratory supports its technical approach, but the app is not a certified medical device, so outputs must be treated as informational and verified with a healthcare professional when concerns arise.
