Teacher: Now, understand the problem? Solve this instance: (CNN) -- So much for Instagram? Facebook on Thursday launched a photo-sharing app called Facebook Camera, which aims to make it simpler for the social network's users to upload and browse photos on smartphones. The news comes only weeks after Facebook spent $1 billion on a similar photo-sharing app called Instagram. And only days after the company's initial public offering got a lukewarm reception from Wall Street and raised the eyebrows of financial regulators. The company says the app, which will be available late Thursday for Apple iOS devices, makes Facebook photos more fun and accessible. "When you launch the app, you'll see a feed of just great photos from the people you care about," the company said in a press release. "You can swipe to see more of any album or tap to enlarge an individual photo."Facebook launches a 'Camera' app on ThursdayThe app lets users edit, filter and share photosIt is being compared to Instagram, which Facebook recently purchasedBloggers say the app was developed before that $1 billion deal
