Asana is one startup we’ve had our eye on for a while. A slick collaborative task and project management app from Facebook co-founder Dustin Moskovitz and ex-Facebooker Justin Rosenstein. It actually started off as a side-project while the pair were still at the social network.

And today Asana has finally landed on Android, 15 months after its first foray into native mobile apps with iOS, an app that was redesigned and rebuilt from the ground up six months ago.

Indeed, mobile was one area where Asana was typically lacking up until its last iOS update, and with an Android incarnation now in tow, this is another string to its bow.

Asana for Android

As with the iOS app, with Asana for Android, you can create, assign and edit tasks on the go, as well as tap-in to existing tasks and workspaces.

You can add comments, set tasks to ‘recur’, and through your mobile inbox you can keep tabs on all your own tasks and projects, letting you add due dates, notes and tags.

One of the features we previously noted was missing with the iOS app was drag-and-drop to reorder tasks on your task list, something that was recently remedied. And this is something we’re pleased to say features in the Android app too.

The search function also lets you peruse a workspace for any task, project or tag, while the mobile inbox (another recent addition) lets you collaborate in real-time with colleagues.

In addition to us at TNW, Asana has a slew of top firms on board, such as Linkedin, Twitter, Foursquare and Airbnb, and the company has previously claimed that 75% of the people who take up Asana stick with it, which isn’t a bad retention figure at all.

It’s been a steady growth for Moskovitz and Co at Asana, a startup which landed a nine million dollar round of financing back in 2009 while it was still in stealth, which followed a $1.2 million dollar round just before that. A $28M round from Founders Fund and existing investors last July brings the total to $38.2M.

In April last year, it launched premium workspaces, which essentially opened the platform to teams larger than 30 people, before rolling out a new Inbox feature, which it said would help cut down users’ email time by up to 50%.

“At Asana, we believe that when you and your teammates have a single, shared tool to plan your work, communicate, and stay organized, your potential expands,” they say in an announcement today.” But to stay coordinated in an always-on, ever-connected world, you need to take that tool with you everywhere, staying in sync with your team whether you’re at your desk or on the way to the airport or anywhere else you might go.”
