Overview
- The device debuts in two packages: Proactive at $349.95 with one cartridge and Intensive at $429.95 with two cartridges and 44 total tests.
- Interchangeable Nutrio and Calci cartridges measure biomarkers such as urinary pH, hydration status, ketones, vitamin C, and calcium linked to kidney stone risk.
- Each cartridge supports about 22 analyses over roughly three months, with replacements priced at $99.95 each or $179.95 per pair and managed through a subscription.
- Users trigger scheduled measurement windows in the Withings app to avoid capturing others’ samples; the unit clips inside the toilet, then recharges and self-cleans between tests.
- The previously announced Cycle Sync reproductive-health cartridge is not available at launch, and the rollout highlights a broader push to embed passive health monitoring in home fixtures.
