Japan has always been at the forefront of bathroom technology. But just when you thought heated seats, automatic air deodorizers, and air conditioning below the rim was cutting edge, one company took the toilet to the next level, creating an app that not only controls it but quantifies bowel movements too. There's just one problem: any toilet is hackable by anyone with the app.

The security firm Trustwave found that anyone with the "My Satis" app could remotely control the Satis-brand toilets, made by Japanese commode company Lixil. All these would-be hackers have to do is enter the hard-coded Bluetooth PIN (0000) and they would have full access to control any of the Satis toilet's features, according to NPR.

"An attacker could simply download the 'My Satis' application and use it to cause the toilet to repeatedly flush, raising the water usage and therefore utility cost to its owner," Trustwave wrote in the warning. "Attackers could cause the unit to unexpectedly open/close the lid, activate the bidet or air-dry functions causing discomfort or distress to user."

The Rolls-Royce Of Toilets

Although it's unclear how the issue will be resolved, the $4,000 toilet might still be worth it. Besides deodorizing and heating, the toilet also has a two-nozzle bidet, and an otohime, which is essentially a "princess sound" that can be played to block out more embarrassing sounds.

But it's in the app that the toilet truly shines. It can manipulate all of the toilet's features, connect your cellphone's music library to the toilet's speakers, and even check-up on detailed records of your bowel movements, which are stored on the commode.

The app's promotional site says that tracking bowel movements is "essential for understanding" your health status, and that having consistent bowel movements is important when looking for any "changes in the body and disorder of the mind."

While it may sound strange, they're kind of right. The shape, color, consistency, and even pain while letting it out, can tell you about your intestinal health. Most importantly, it can tell you if you're getting enough fiber in your diet.

Poop Speaks Volumes

"On average we're supposed to get at least 25 grams [of fiber] per day," Dr. Anish Sheth, author of What's Your Poo Telling You?, told ABC News. "The average American gets about 10, and that can actually manifest itself in the size, consistency, and frequency of our bowel movements."

Looking at color can tell you various things as well. According to Mayo Clinic, green stool can be an indicator quick movement through the large intestine, while black stool can be an indicator of bleeding in the upper gastrointestinal (GI) tract.

"Blood can also have a dark, tarry black consistency as well, and that's actually if you're bleeding more slowly from higher up in the GI tract. If you have an ulcer in your stomach or abnormal blood vessels in your intestines," Dr. Sheth said. "So even darker stools can be a sign that you need to see a doctor."
