Should I Sleep 1.0.3 – Prevents your display from sleeping by using face detection and other sensors

Should I Sleep will revolutionize the way your computer enters sleep mode to save energy. Instead of preventing sleep for a fixed amount of time, Should I Sleep uses a combination of unique heuristic sensors (such as face detection) to check if you are actually at the computer before it sleeps.

HOW IT WORKS When the display is about to dim (due to keyboard and mouse inactivity), Should I Sleep will start its sensors. Camera, microphone all other software processing will stay on for only about 3 seconds. After that (and depending on your sensor preferences), sleep will be allowed or prevented. No need to touch any button.

FACE DETECTION Give a life to your camera: Face Detection is the most effective sensor and works by capturing video from the camera just before the display is dimmed. If one or more faces are detected, sleep is prevented.

CAMERA MOTION Sleep is prevented if a moving object is captured by the camera (such as waving, walking or even slightly moving your head). A perfect combination for the default Face Detection as it works even when you are not directly facing the camera.

EXTERNAL DISPLAY Prevent sleep if an external display is plugged-in. A must-have for those who give presentations, speeches, demonstrations and/or trainings.

SOUND ACTIVITY Prevent sleep If ambient sound is detected. Useful in workshops, brainstorming, meetings and conversations where the camera may not be in a favorable position.

CUSTOMIZATION On the preferences screen you’ll be able to adjust sensors sensitivity so that Should I Sleep can work more effectively on unusual environments (especially on very noisy or crowded places).

MORE SENSORS Should I Sleep was developed with a modular, expandable approach. We believe that the best sleep prevention is done by analyzing as many environmental elements as possible. That’s why we’ll be actively adding more sensors in the near future. Feel free to send us your ideas.

MANUAL MODE Well, we’re not sure you’ll need this. But just for the sake of completeness, we have also added the old-style timed sleep prevention. You just choose a predefined time period for the computer to be kept awake. This mode also prevents screensavers.

DO I NEED IT? Having the display dimmed when we’re focused on the computer is certainly annoying. Staying alert to “press any key” and prevent (or worse, fix) that, is disturbing and counterproductive. And that may happen during many activities, such as:

  • Carefully reading a web page, book or documentation.
  • Following the progress of a software operation.
  • Doing a presentation, training or demonstration.
  • Listening to a song and following on-screen lyrics.
  • On a conversation, taking notes between intervals.


  • Sleep prevention with unique heuristic sensors.
  • Timer mode for display and screensaver prevention.
  • Face detection – the most effective sensor – free.
  • Additional sensors available as affordable in-app purchases.
  • Blazing fast, 3-second, hardware-accelerated detection.
  • OS X 10.8 notification center integration.
  • Sensor sensitivity and accuracy fine-tuning.
  • Modular development approach (more sensors on the way).

Should I Sleep is available for free download from the Mac App Store. It includes the Face Detection sensor and manual timer mode for free. Additional sensors can be purchased for an affordable price from within the application menu. Check the demonstration video on our home page.
