## What is Nyxtune?

Last night, roughly as you remember it, is enough. Nyxtune is a sleep journal for people who struggle to fall asleep, built for staying with it rather than for precision. Informed by the ideas behind CBT-I (cognitive behavioural therapy for insomnia), it brings your nightly log, a weekly look back, and short readings about sleep together in one place.

■ A sleep log you can keep roughly
Record when you went to bed and got up, how long it took to fall asleep, and how often and how long you were awake during the night. It is built for staying with it rather than for precision — a rough estimate from memory is fine.

■ Tonight and tomorrow, at a glance
Your day is laid out on a timeline, anchored to the wake-up time you set. Opening the home screen is enough to see what comes next.

■ Patterns take shape as you go
Once entries build up, you can see how your sleep duration and time-to-sleep move over the weeks.

■ Learn about sleep, a bit at a time
Short readings cover how sleep works and how to sit with a night you can't sleep through. More opens up as you keep logging.

■ Everything stays on your device
Entries are stored and charts are calculated on your device, so they work without a connection. You can write your entries out to a file from the settings screen.

■ A quiet design made for the dark
Built to be opened before bed, with colours that don't glare in a dark room. Available in English and Japanese.

■ About the subscription
The features described above require a paid auto-renewing subscription; every feature apart from the initial setup is for subscribers. The price and renewal period are shown on the purchase screen in the app. It renews automatically unless cancelled at least 24 hours before the end of the period, and you can cancel any time from your App Store account settings. Exporting your data and deleting your account remain available without a subscription.

■ Please note
Nyxtune is not a medical device and does not diagnose or treat insomnia. It is not a substitute for care from a doctor or other professional. If you cannot sleep night after night, or you notice low mood or strong anxiety, please talk to a healthcare provider or a support line.
The content draws on general knowledge about CBT-I, but makes no claim about the clinical effect of this app itself. It has not been reviewed by a clinical specialist.
