Quote from: Kirill on July 27, 2026, 14:23:50This statement is incorrect. All primary sleep tracking features—including detailed, minute-by-minute charts—are completely free, and I have been using them daily for two years. In the European version of the app, any related promotions can be entirely disabled in the settings. The author misleads readers by omitting screenshots of the sleep tab, likely because doing so would disprove their claims.

I think the same principle applies when evaluating fitness and health data: you need to look at the actual detailed measurements rather than relying on a simplified summary. For example, body composition can change even when body weight stays relatively stable. A body fat calculator can provide a useful estimate based on basic body measurements, and the Navy method is convenient because it doesn't require any specialized equipment. Similarly, with sleep tracking, detailed charts and actual data should be considered before concluding that certain features are unavailable or paid.
