DozyBlue

Pick up where you left off

DozyBlue is a sleep-aware app that recognises when you drifted off whilst enjoying your favourite media. Whether you’re immersed in an audiobook, catching up on a podcast, or watching films or series, it seamlessly connects with Apple Health to pinpoint your sleep onset, estimate the moment you nodded off, and calculate your media resume window — ensuring you can effortlessly pick up where you left off.

All you need is a compatible sleep tracker

DozyBlue works with sleep tracking devices that sync sleep data to Apple Health on iPhone. If your device records sleep and shares that data with Apple Health, it can be used with DozyBlue. Your tracker records your sleep as normal, and DozyBlue uses the sleep data available in Apple Health to estimate when you fell asleep and suggest where to resume your media.

Key features

Sleep-aware resume

DozyBlue estimates when you drifted off using data from your sleep tracking device in Apple Health, then suggests the right place to continue your media.

Media smart

DozyBlue supports films, series, podcasts, and YouTube videos — with the flexibility to also add audiobooks or any audio/video manually.

Pre-Content Rewind (PCR)

DozyBlue allows you to fine-tune how long it usually takes you to fall asleep so resume points feel natural and memorable.

Advert handling

If your media includes adverts, mark them as expected. DozyBlue will ask about them at the end of your session and adjust your progress accordingly.

Episode chaining

Autoplaying episodes? DozyBlue will follow the next episode to keep resume estimates accurate across your sleep session.

Continue previous sessions

DozyBlue remembers your previous sleep sessions and pre-fills the details, so you can continue a previous session with just a few taps.
