A bra that can test "true love"? There's an app for that. Oh, and of course, a bra.

As website IT Media reports, Japanese lingerie maker Ravijour has developed a "True Love Test" as part of its 10th year anniversary.

The company is marking that milestone with the theme "Mood Up." And unusual underwear.

You can see how it works in the video below:

The tech sounds vaguely somewhat like the smart bra Microsoft has been working onโ€”minus the emotional overeating tracking bit. Or perhaps Nintendo's Love Tester.

But as NicoNico reports, the True Love Tester is currently not for sale. But! If you purchase over 5,000 yen (about US$50) worth of Ravijour lingerie, you can enter to win a chance to test it out at hotels in six different cities (you pick the city!) across Japan. Five lucky couples will be selected.

So, yes, this is part of a promotional campaign. It's also the first time a bra like this has been developed. For science!
