It’s one of the most hassle-free ways to monitor your night, and at 99 cents, it’s the best deal in dreamland.

It just works. Period. It does exactly what it advertises which is absolutely amazing.


I’ve used the app for months now and truly believe it works… and I love seeing graphs of my sleep patterns over time.

The result is so gentle and lovely it feels like being woken up by a mermaid stoking your hair or a unicorn nuzzling your toes.

The Guardian

The app can wake you from the lightest phase of sleep, which is the natural waking point.


I was a little sceptical at first, but I’ve been surprised by the results.
