Sleep Tracker - Sleep Recorder

Sleep Tracker - Sleep Recorder is an app that monitors sleep cycles, records snoring, and provides sleep-aid sounds. It allows users to view sleep depth and cycles, explore sleep trends, record night voices, and customize smart alarms. It also includes a feature to log sleep notes and wake-up mood, which aligns with the 'mood-and-fatigue-tracker' feature. While it tracks sleep data, it doesn't explicitly offer comprehensive educational eBooks or personalized care plan templates for sleep apnea, which are must-have features for the ApneaCare Companion. However, it does offer daily tracking and reminders, and the ability to export data, making it a partial match.
