User Reviews

The app is praised for its accurate sleep tracking when paired with Polar H10 and its intuitive design that offers helpful sleep insights. However, multiple users find the subscription pricing prohibitively expensive and feel the free version lacks meaningful features. Common issues include bugs, limited data export, interface confusion regarding sensor connectivity, inability to log multiple sleep sessions daily, and lack of integration with other fitness platforms. While the technology is impressive, significant improvements are desired to justify the high cost and enhance user experience.

Pros

Highly accurate sleep tracking especially when used with Polar H10 sensor.
Intuitive and visually comfortable user interface.
Provides useful insights and helps users understand their sleep patterns.
Responsive and helpful customer support.
Compatible with comfortable and relatively inexpensive sensors instead of requiring smartwatches.

Cons

Very expensive subscription price (around 20-25 euros/month), making it unaffordable for many users.
Free version provides limited functionality with many features locked behind a high paywall.
User interface issues including unclear sensor connectivity status and inability to record multiple sleep sessions per day (e.g., power naps).
Bugs and occasional inaccuracies such as reporting zero awake time, which is unrealistic.
Lack of data export options and limited integration with other apps such as Google Fit.

Recent reviews

Wish it was possible to export sleep cycles to google fit, good accuracy and insights otherwise

Tooo expensive. And the free version does not show you enough to even make it worth using it. Devs think people can afford to pay subscribtion for everything nowadays. 20/month is crazy.
