Update: Quist owner Sarah Prager received a phone call from an Apple representative Tuesday telling her that the use of "bisexual" is no longer flagged in the company's App Store.
"I'm very pleased Apple responded positively," Prager said in a statement. "It is important that we all stand up for every letter in LGBTQ and not treat the bisexual community as a spam word."
Quist first announced the news in a tweet from its official account Tuesday morning.
