API service provider Mashery (a ProgrammableWeb sponsor) has launched a new app directory at SXSW which features apps built on Mashery hosted APIs. It’s a great thing for three distinct groups. First, it helps the API providers who partner with Mashery by encouraging API usage through the apps. Second, it helps app developers seeking to build an audience. Third, it helps consumers that might be interested in finding an app that uses a particular API. Granted, those would be your super savvy mobile app consumers, but that doesn’t seem so far fetched after a week at "spring break for geeks."
Aviary, the photo editing suite that includes a number of Aviary APIs to incorporate photo editing into your web applications is moving its tools to mobile. Today it announced SDKs for iPhone and Android, as well as an impressively long list of launch partners who have already incorporated the platform in their mobile apps.
