The Newest Health Trend Is Tracking Your Pee

when my dog Sniffing certain spots during our morning walks, my daughter calls it “checking your pee matches.” Yes, that’s right in the animal kingdom: Urine carries health information, and by analyzing it, you can access important data about your body without wearing a fitness tracker 24/7 or getting stuck with needles.

Over the past few months, I’ve been inundated with a steady stream of urine trackers, of which Vivo’s Smart Toilet is the latest. The smart sensor debuted at CES 2026 and went on sale this week. It costs a relatively affordable $99 and clips inside any toilet basin.

When you’re ready to go about your business, connect the sensor to its companion mobile app using Bluetooth. The sensor collects a sample for testing and uses an optical sensor that measures the specific gravity of your urine. An onboard processing unit then uses proprietary algorithms to tell you whether you’re hydrated or not. Most importantly, this gadget uses antibacterial components, has antifungal nanotechnology, is designed for over 1,000 uses, and is completely touch-free.

Since I potty trained my kids I’ve been spending more time on my toilet than ever before. I recently tested the Withings U-Scan, which is a more expensive and more premium-looking urine analysis device at $380. There are two versions: Nutrio checks for ketone levels, hydration status, and urine acidity (basically, for diabetes), and Calc checks for the calcium content in your urine, which is an early indicator that you may have kidney stones.

Like a smart toilet, the U-Scan opens and uses a cartridge to take urine samples. This means it’s not completely waterproof, and you have to aim as you go, which required some fun and necessary conversations with my husband about placement. Plus, you have to take it out of the toilet to clean and charge it when you change the cartridge, which is about every month. Helpfully, the cartridge replacements come with a pair of rubber gloves.

Still, it’s a much better and safer process than the one with Kohler Decoda, which was also announced last year. It’s basically a toilet bowl camera; It takes photos of everything you deposit in your toilet and uses AI to analyze it and give you recommendations on your gut health. Only, it turned out that the end-to-end encrypted camera wasn’t actually end-to-end encrypted. Also, its price is $599.

About a decade ago, the idea that someone would want to track what’s going on in their toilet was so universal that Adult Swim copied the concept. But now, we are not only tracking our steps and heartbeats but also testing our blood and saliva. The idea of ​​keeping an eye on what’s going on in our toilets doesn’t seem so strange anymore.
