Google Play and Apple have rejected an app designed to help women post nude photos on Instagram.
Model Melina DiMarco has designed an app to provide simple illustrated "lady parts" to post over your own, to get round the sites rules on nudity.
She claims other options for censoring photos, for example black bars and crosses, encourage the sexualisation of the female form.
But the App Store and Google Play Store say her app promotes explicit content.
