Vivoo brings lab-style hydration tracking to your bathroom

A toilet sensor that reads your hydration level in seconds is not something you see every day. But that’s exactly what Vivoo is now offering.

Vivoo puts hydration tracking on autopilot

The new Vivoo Smart Toilet is a clip-on sensor that fits onto your existing toilet bowl. It works during normal use, runs without user input, and beams data to your phone within minutes.

This is not Vivoo’s first foray into urinalysis, but it’s by far its most streamlined. Previous offerings from the company relied on urine test strips and phone-assisted scanning. The new version moves everything inside the bowl. A tiny scoop collects a small sample mid-stream, then passes it through a chamber where onboard optical sensors measure specific gravity. The result is a hydration score, accurate enough to replace guesswork and manual logging.

It takes less than a minute to complete a scan, and there’s no need to alter your bathroom routine. Once set up, the system runs in the background. The sensor connects to the Vivoo app, where you’ll see your hydration status and get simple recommendations on what to do next.

Aiming for everyday integration

Vivoo’s sensor is designed for simplicity. It’s rechargeable, lasts over 1,000 tests per charge, and is easy to remove for cleaning. Early adopters who order now get a version with no subscription fees, although future buyers will need to pay $5.99 per month for app access starting in September.

Unlike systems that rely on cartridges or recurring supplies, this one doesn’t require physical test strips. That helps keep ongoing costs down. It also means fewer things to replace or maintain.

Beyond hydration, the Vivoo app can already analyse test strips for a wider panel of biomarkers, including ketones, vitamin C, calcium, magnesium, and more. But the Smart Toilet focuses on hydration for now, offering one clear metric delivered passively.

Positioning against Withings

There’s an obvious point of comparison here. Withings’ U-Scan system launched earlier with a similar concept but takes a more mechanical approach, involving cartridges that need changing and specific user targeting for each stream. Vivoo’s system skips all that. It’s less complex, and potentially more scalable, especially for households with multiple users.

Pricing is also a factor. Withings’ device is more expensive upfront and long-term. Vivoo is trying a different angle – less hardware complexity, lower entry cost, longer lasting as there are no physical consumables, at least for this model.

From hydration to hormone testing

Alongside the Smart Toilet, Vivoo has announced a second sensor-based product. The Hygienic FlowPad is a smart menstrual pad that can track biomarkers related to fertility and ovarian function. This one does require manual scanning after use, but it adds another layer to Vivoo’s growing interest in at-home biochemical tracking.

At $4 to $5 per pad, it’s positioned as a monthly-use product for people looking to understand their cycle better through FSH and related hormone levels. While still early, it points to a broader strategy from Vivoo—turn everyday items into data sources.

Not just data, but advice

Vivoo isn’t only focused on diagnostics. The app is built around providing personalised, actionable suggestions. When it flags hydration issues, it doesn’t just tell you that you’re low. It gives you context, tracks your historical patterns, and helps guide your next steps.

That advice engine is grounded in a large recommendation database, built from thousands of scientific papers and vetted by a team of dietitians and doctors. There’s also an AI assistant named Welly that helps explain the findings and supports you in making changes.

Vivoo says its system delivers over 96 percent accuracy across its parameters, though this is based on internal validation and third-party reports not yet widely available. Still, the combination of image processing, real-time analysis, and a clear feedback loop makes it more than just a tech gimmick.

Early bird pricing and next steps

The Smart Toilet is available now for $99 as part of an early launch window, shipping in March. This includes app access at no extra cost. A second launch batch is scheduled for July at the same price but with a $2.99 monthly fee. By September, the price goes up to $129 with a $5.99 per month app subscription.

Quantities are limited for the early batches, and Vivoo is already warning that initial units may sell out quickly. For anyone interested in low-effort hydration tracking or curious about the future of passive health monitoring, it’s an unusual but potentially useful new option.
