A new app is hoping to provide women with some support — for their breasts.

ChiChi, which translates to boobs in Japanese, will help women measure their busts so they can buy the proper size while bra shopping.

“Place your smartphone between your breasts and you’ll find your cup size,” one ad for the app boasted.

Developers in Japan are still testing the app, which is set to go on sale next month.

But its busty benefits are being slammed by feminist groups that say it serves an unnecessary purpose.

“A woman can tell instinctively if a bra fits her or not,” a Japanese group told Central European News. “We consider it a gimmick best avoided.”
