Pasadena-based Wallaby, the developer of mobile apps to help consumers pick the best credit card to use for a purchase, said today that it has launched both a new, Google Chrome web browser extension, as well as an updated, iPhone application. Wallaby's Chrome Extension lets users pick the best credit card for their online purchases at merchants, helping users to optimize their points and rewards for what they're buying online at e-commerce sites. Wallaby said the Chrome extension works with a wide range of merchants, including Amazon, eBay, Staples, and others. The company's new iPhone application update includes personalized suggestions on cards, and the company said the update is its most significant since its original iPhone release in 2012. Wallaby is led by Matthew Goldman.
