Real-time BPM dashboard
Live blinks-per-minute, session duration, blink count, last-blink indicator, and status — glanceable at a distance.
On-device blink tracking
Know your blink rate.
Not your data.
BlinkSense watches your blink-per-minute rate in real time while you work, and gives you a gentle nudge when it drops into a low or critical zone — using the front camera you already have, processed entirely on-device.
BlinkSense is an awareness tool, not a medical device. It does not diagnose, treat, cure, or prevent any condition.

Why blink rate
Deep focus quietly drops your blink rate — and you won't notice until your eyes do.
Reading, coding, designing, and meetings on screen can cut blink rate well below its resting baseline. BlinkSense keeps a private, real-time readout of that rate so a drop is visible before it becomes discomfort.
How the detection pipeline works
From camera frame to alert, entirely on-device.
- 01
Capture & landmarks
The front camera feeds a local vision pipeline — Apple Vision, ML Kit, or ARKit TrueDepth blend shapes — that finds your eyes every frame.
- 02
EAR & calibration
Left and right Eye Aspect Ratio is computed against its own baseline, calibrated only from plausibly open-eye frames so a closed-eye startup can't poison it.
- 03
BPM & alert zones
A debounced blink-state machine produces a rolling BPM, compared against healthy / low / critical zones with quiet hours and category-aware thresholds.
What's in the app
Everything the dashboard actually does.
Alert zones
Healthy, low, and critical zones with configurable thresholds, quiet hours, and category-aware sensitivity.
Session categories
Tag sessions as Work, TV, Reading, Gaming, or Other so trends reflect what you were actually doing.
Local history & charts
Every session is recorded on-device with BPM trend charts you can review — nothing leaves your device.
Docked Mode
A keep-awake, dimmed near-black overlay so a phone or Mac can sit docked on the desk and keep tracking without sleeping or glaring.
Debug camera overlay
An optional live view of face/eye landmarks and per-eye EAR values, for verifying tracking quality.
macOS only
Performance diagnostics that stay on your Mac.
BlinkSense tracks thermal-state transitions, capture/Vision FPS, dropped frames, CPU time, and resident memory so you can see how tracking is behaving — and steps analysis down automatically under thermal load. Diagnostics are counters only: no camera frames, no face data, and the JSON export never leaves your device.

Private by design
Your face is not our product.
All camera analysis runs locally on your device. No camera frames, facial data, or session video ever leave the device or get uploaded — verified in Settings and in the code itself.

On-device processing
Every frame is analyzed locally — there is no networking path in the tracker.
✓
No video upload or storage
Camera frames and face data are never recorded, sent, or stored off-device.
✓
Diagnostics stay local
macOS performance counters export to JSON on your device only — never uploaded.
One blink model, five platforms
Built native for where you actually work.
macOS
Swift / SwiftUI · AVFoundation · Vision
Front camera, EAR-based blink detection, adaptive thermal policy, and local performance diagnostics.
Windows
Electron · local Vision/landmark pipeline
Webcam landmark-to-EAR mapping, with a Setup installer and Portable fallback.
Android
Kotlin / Jetpack Compose · CameraX · ML Kit
Face contours drive EAR calibration and blink state; the dashboard session owns the camera lifecycle.
iOS Vision
Swift / SwiftUI · AVCaptureSession · Vision
RGB front-camera face landmarks — works on any iPhone front camera.
iOS Sense
Swift / SwiftUI · ARKit
TrueDepth blend shapes (eyeBlinkLeft / eyeBlinkRight) for the highest-fidelity signal on compatible iPhones.
Device validation pre-releases
Device Test Builds
These downloads are pre-releases for device validation only. They are not medical devices and are not production releases. Builds are currently unsigned — expect a Gatekeeper or SmartScreen warning.
Choose your Mac
Use Apple Silicon for M-series Macs. Use Intel for Intel-based Macs.
Setup is recommended
Choose Windows Setup for the usual installation. Use Portable only if Setup is unavailable for your device.
Android & iOS
Android APK installation may require enabling installs from unknown sources. iOS requires TestFlight or Xcode and is not downloadable yet.

Questions, answered
Clear about what BlinkSense is—and is not.
We believe thoughtful technology starts with plain language.
Is BlinkSense a medical device?
No. BlinkSense is an awareness tool. It does not diagnose, treat, cure, or prevent any medical condition, and it is not a substitute for professional medical advice.
Does BlinkSense record me?
No. All camera analysis happens locally on-device. No camera frames, facial data, or session video ever leave the device or get uploaded — there is no networking path in the tracker.
What is Docked Mode?
A keep-awake, dimmed near-black overlay for when your phone or Mac sits docked on the desk facing you. It stops the display sleeping or glaring while tracking continues in the foreground — camera access on iOS can't run in the background, so Docked Mode is the accepted workaround for desk-docked counting.
Which devices does it support?
macOS (Apple Silicon and Intel), Windows, Android, and iOS — with a Vision app using the front camera and a Sense app using ARKit TrueDepth on compatible iPhones. Download links for current device-test builds are below; iOS requires TestFlight or Xcode until the Apple Developer account is active.
Will it interrupt my work?
Alerts are configurable per zone, category-aware, and support quiet hours — you decide when and how BlinkSense speaks up, and can pause it anytime.
