## What is Nod?

Lying awake at night, waking at 3 a.m., tired every morning? Nod is a six-week, self-guided sleep program. It is built on techniques from cognitive behavioural therapy for insomnia (CBT-I) – the approach clinical guidelines name as the first choice for persistent sleep problems. Five minutes a day, no account, nothing to wear.

Nod is not a sleep tracker and not a library of sounds. Nod measures nothing. Step by step, you learn the habits that give your sleep a steady shape again.

A DAY WITH NOD
• Morning: a 30-second sleep diary. When were the lights out, when did you get up, how long were you awake? Nod works out your sleep efficiency. With an Apple Watch or any other source in Apple Health, the times are filled in for you.
• During the day: one short lesson, three to five minutes. 42 lessons explain why good sleep does not come from trying harder – and what helps instead: a fixed rise time, a sleep window, stimulus control, dealing with a racing mind, relaxation, planning for setbacks.
• Evening: a guided wind-down. Day check, park your worries, 4-7-8 breathing or muscle relaxation – then put the phone away.
• Night: when you lie awake, Nod guides you calmly through the moment – breathing, a body scan, the cognitive shuffle or the get-up rule. This screen never shows the time, on purpose.

WHAT ELSE NOD DOES
• A personal sleep window: worked out from your diary and adjusted every week, with a separate plan for days off. Nod only ever suggests shortening it – you decide.
• Progress: sleep efficiency, time to fall asleep, time awake and total sleep for 7 days, 4 weeks or a year.
• Patterns: if you like, Nod compares your nights with day factors from Apple Health and your day check – steps, workouts, caffeine, alcohol, water, mindful minutes.
• A PDF report to take to your doctor.
• A Lock Screen card, widgets, Siri shortcuts and an Apple Watch app for the check-in, breathing and night help.
• In ten languages.

PRIVATE BY DESIGN
No account. No servers. No ads. No tracking. Your diary and all health data stay on your iPhone. Apple Health is only read, never written to – and only if you allow it.

NOD PREMIUM
The sleep diary, the evening routine, the night help and the first week of the program are free. Nod Premium opens weeks 2–6, the personal sleep window, the patterns and the PDF report – as a monthly or yearly subscription with a 7-day free trial for new subscribers, or as a one-time purchase with no subscription. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage and cancel them at any time in your Apple Account settings.

IMPORTANT
Nod is a wellness and education app, not a medical device. The method is well studied; Nod itself has not been clinically tested. Nod does not diagnose anything and is no substitute for medical or psychological care. The sleep window is not suitable for everyone; Nod asks about common contraindications and switches it off where they apply. If your sleep problems persist, or if you take medication, talk to your doctor.

## Version history (last 5 releases)

### 1.2.5 — 2026-10-11

„Morning check-in: once you’ve estimated your time to fall asleep and time awake, saving no longer asks again. If one of them is missing, the prompt now names exactly that one.“

### 1.2.4 — 2026-10-07

New app icon: a moon with a sprout.

### 1.2.3 — 2026-10-02

• Redeem a code right below the prices and any time in Settings – also during the free trial week.
• Evening routine reminder: now arrives more reliably at your chosen time before bed, even when Nod is closed and your iPhone is locked. Settings › Reminders shows when the next one is due.
• The evening routine now starts 30 minutes before bedtime by default.
• Minor improvements and fixes.

### 1.2.2 — 2026-09-28

New: see what affects your sleep

• What affects your sleep: Nod now puts your days next to your nights – steps, activity, daylight, standing, workouts, water, calories, protein, carbohydrates, fat, fibre, sugar and late meals from Apple Health (from any app that logs them there, such as Yazio). A new day grid shows your pattern at a glance; every pattern comes with real numbers, each night as a dot, and a clear or provisional label. First patterns after 10 nights.
• Morning check-in: “Got up” is the moment you tap to log the night. Nothing is pre-filled that Nod did not actually record – the estimates are yours.
• Optional alarm (iOS 26.1 or later): Nod can ring at your rise time, counts every snooze and takes stopping it as the moment you got up.
• Redeem offer codes right in the app.
• Smaller fixes and improvements.

### 1.2.1 — 2026-09-26

Bug fixes and improvements

• Daylight saving time: times and your sleep plan stay correct on the day the clocks change.
• Reminders stay reliably scheduled, and the evening reminder no longer arrives once you're already in bed. On free days, reminders come at the right time.
• Diary: a night you've already logged opens for editing instead of being overwritten. You can now delete single nights.
• Progress: the charts are more precise – every label sits right under its bar.
• Apple Watch: check-ins are merged safely (your notes are kept), the Watch shows your plan on free days too, and breathing keeps going with your wrist lowered.
• App Lock now also covers open screens and the app switcher.
• More small improvements to export, accessibility and display.
