Does this sound familiar?
- You get into bed but take a long time to fall asleep
- You wake up several times in the night and struggle to get back to sleep
- Your bedtime and wake time change from day to day
- You are not sure how much you actually sleep
Sleep medicine guidelines recommend CBT-I as a first-line approach for chronic insomnia, and its starting point is a sleep diary: a short daily record of your sleep. A diary shows more than the impression that you slept badly. It shows when you actually went to bed, how long it took to fall asleep, and how many times you woke up. Read more about CBT-I at home

A sleep diary, not a sleep tracker
Many sleep apps measure your sleep with a smartwatch or a phone beside your pillow. Nyxtune is different: you fill in a diary yourself in the morning. You do not need a wearable, and you do not need to keep your phone on the bed. The sleep diary used in CBT-I includes how you felt about the night, and Nyxtune's items follow that approach.

Frequently asked questions
What is Nyxtune?
Nyxtune is an iPhone sleep diary app based on the sleep diary used in CBT-I (cognitive behavioral therapy for insomnia). Each morning you log bedtime, wake time, how long it took to fall asleep, and how often and how long you woke up, then review charts of your sleep time and time to fall asleep. It is developed by suplum.
Who is it for?
People who have trouble falling asleep, wake up during the night, or have had a run of sleepless nights, and who want to see their actual sleep pattern by keeping a diary. It also suits people who prefer not to use a smartwatch or other device.
Can I do CBT-I with an app on my own?
The sleep diary is the foundation of CBT-I, and Nyxtune is built to help you keep it. Nyxtune is not a medical device and does not replace CBT-I from a clinician. Make large changes to your sleep schedule, such as sleep restriction, with a professional.
Is Nyxtune a medical device?
No. Nyxtune is not a medical device and does not diagnose any condition. It is a tool for recording and reviewing your sleep habits. If poor sleep continues for weeks or affects your daytime life, see a doctor.
Do I need a smartwatch or other wearable?
No. Nyxtune does not measure your sleep with a device. You fill in a sleep diary each morning from memory. You don't keep your phone in bed, and it does not record sound while you sleep.
