Springpad, a productivity app that struggled to stand out from similar offerings from Evernote and Pinterest, is planning to close its doors, The Verge has learned. The six-year-old Boston company, which raised more than $7 million, had around 400,000 people using its digital notebooks to save tasks, notes, checklists, and more. But it never came close to matching the momentum of Evernote, which said this month that it now has over 100 million users.

It's unclear when the service will end or how Springpad plans to tell its users, but the move appears imminent, according to a person familiar with the company's plans. Last year, Springpad incorporated features into its app to make it feel more like Pinterest, letting users search public posts and follow other users' notebooks. But the company never developed a unique identity in a landscape crowded with better-funded and slicker alternatives. The company hasn't tweeted since May 1st, though it seems to still be fielding requests on its support account on Twitter.

The team behind Springpad plans to build a new product, a source said, but it's unclear what it will be.

Springpad declined to comment on this story.

Update: Springpad has confirmed its closing in a blog post. The service will shut down on June 25th. "At that point Springpad.com will no longer be available, all online and sync features of the mobile apps will stop working, and your personal data will no longer be stored on our servers," the company said. It will make available an export tool to help users with the transition to another service.
