Withings first announced its U-Scan, a non-invasive device you install in your toilet to track various health metrics, at CES 2023 two years ago. Unlike Kohler’s Dekoda, which uses a camera to analyze your poop, the U-Scan detects and samples your urine, tests it using replaceable cartridges, and sends the results to the Withings app, where you’ll get tips on how to improve your health if needed.

The device is finally launching in the US and Europe today with two different cartridges. The U-Scan Nutrio monitors nutrition by measuring four urinary biomarkers — including hydration, ketones, and vitamin C — while the U-Scan Calci tracks parameters such as calcium levels to monitor kidney health and the potential for developing kidney stones. The cartridge for tracking reproductive health that was announced alongside the U-Scan at CES 2023 won’t be available at launch, and while the device was originally waiting for FDA clearance, Withings now classifies it as a “wellness product,” so clearance isn’t necessary.

Pricing starts at $349.95 for the Proactive option, which includes the U-Scan itself, a charging and cleaning station, access to the Withings Plus service, and a single Nutrio or Calci cartridge with 22 tests that will last up to three months with just two weekly measurements. The $429.95 Intensive option instead includes two cartridges and 44 tests, facilitating more tests per week. Replacement cartridges, which can be shipped regularly as part of a subscription plan, are $99.95 each or $179.95 a pair.
