Twitter co-founder Biz Stone launched Super — the second mobile app from his Jelly Industries operation — which enables users to share ideas and observations combined with images.

The app has built-in prompts to start messages, such as ‘I’m thinking’, ‘Check out’ or ‘The best’, which users can complete with the addition of text and a photo from a preloaded selection or taken by their smartphone.

“I’ve decided not to come up with some slick and pithy marketing description for Super. I’m also not going to proclaim that it’s the most innovative thing ever or that it’s going to save the world. It’s not, it’s just fun,” Stone said in a post on the Medium blog.

“We laughed a lot while prototyping Super and that was a sure sign we were onto something. I remember doing just that when we were prototyping Twitter eight years ago,” Stone added.

The app has been beta tested, with feedback determining what features to retain or cut from the first release. Stone said there are more ideas for Super in the pipeline but that these are being held back until the app is being used more widely.

Jelly, the first release from the business in January, helps users ask questions with the help of pictures. Like Super, Jelly was released on Apple’s App Store and Google Play.

It’s designed to “search the group mind of your social networks” but is pitched as more than a search engine.

“Jelly changes how we find answers because it uses pictures and people in our social networks,” a company blog stated. “It turns out that getting answers from people is very different from retrieving information with algorithms.”

Jelly was updated in March to include the ability to ask questions using the smartphone’s camera and an interactive map. The process for asking a question was also improved.

Stone co-founded Jelly in 2013 with Ben Finkel, who came to Twitter after his social Q&A service Fluther was acquired in 2010.

Jelly investors have strong links to Twitter. The WSJ previously reported that Spark Capital’s Bijan Sabet, an early Twitter investor, is on the board of directors, as is Twitter chairman Jack Dorsey, Twitter co-founder Evan Williams and Jason Goldman, an early Twitter employee.

Spark Capital led the first big funding round, which closed in May last year. The amount raised was not disclosed. Other investors include singer Bono and LinkedIn founder Reid Hoffman.
