My Sleep Tracker.

As of December 2023, the My Sleep Tracker app is no longer available from the Microsoft Windows and Google Android app stores. This is due to changes in the requirements for advanced applications impossed by Microsoft and Google. If we can find time to rearchitect My Sleep Tracker to meet the new requirements, we may release a revised version of the app in mid 2024. Tentatively, the revised version of the app will be free, but will not include the sharing feature to directly connect sleep therapists with their clients sleep records. Instead clients will need to manually share screen shots with anyone they wish to have their data (such as their sleep therapists).

An easy-to-use application for keeping track of sleep patterns and activities that effect your sleep or insomnia.

The perfect companion app for sleep therapists and people being treated for insomnia.

  • Anyone can record and analyze sleep-related information for free.
  • Easily see charts and sleep statistics to help you understand the most important features of your sleep.
  • As of December 2023, the My Sleep Tracker is no longer available from the app stores. See above for details.
  • If you want, you can share sleep information with your sleep therapist or doctor (if you both opt-in).
  • Designed for use with CBTI (Cognitive Behavior Therapy for Insomnia).
