Cambridge-based car sharing service Zipcar, which recently beat the street with shares soaring 60% in their initial public offering (IPO) just weeks ago (Nasdaq: ZIP), has released a new Android app.

According to the company, an incredible 90% of its members own smartphones. When the company conducted a study this past December with members on device type ownership, they found that the share of Android owners had skyrocketed.

At its core, the app allows members to search for, find, and reserve Zipcars in their area. Like online, users can perform these searches by time, location and vehicle type. And like its iPhone app, the app also delights. It includes features that allow you to unlock your reserved car right from the app — and even honk it’s horn. If you’re not a Zipcar member, you can also download the app to learn more about Zipcar and membership.

The beta release means Zipcar is allowing members to provide timely feedback back to the company so it can expand features and ensure it is delivering a rich and seamless experience. Companies as large as Zipcar rarely do this when releasing apps, so it is great to see the company opening up a dialogue with customers in this way, as it certainly conveys a commitment to the customer and providing the best experiences possible.

The launch expands Zipcar’s mobile portfolio, which already includes iPhone and iPod Touch apps. Time ranked this app as one of the 50 Best iPhone Apps of 2011. When the iPhone 3GS was released back in 2009, Apple chose this Zipcar app for feature in one of its commercials for the device. The company also has a mobile website for non Android or iPhone owners, as well as 2-way texting alerts.

“We offer car ownership, one hour at a time and we are dedicated to pushing easy-to-use, self-service innovations through the entire spectrum of our service. The beta launch of our Android app, demonstrates our continued commitment to delivering the best member experience in the category,” offered Zipcar Chairman and CEO Scott Griffith.

Zipcar’s IPO has made it a billion dollar Boston company – and we look forward to following their expansion plans, both geographically as well as with new services like these apps.
