Instagram has reportedly asked Luxogram to stop using 'gram' in its application name. Jeff Broderick of Luxogram has posted an email on his Twitter account sent by Instagram.
The mail states, "We appreciate your interest in developing products that help people share with Instagram. While we encourage developers to build great apps with Instagram, we cannot allow other applications to look like they might be official Instagram applications or endorsed or sponsored by us."

"It is important that you develop your own distinctive branding for your applications and use Instagram's trademarks only as specifically authorized under our policies," Instagram wrote in the e-mail to Luxogram.
