Build any apps lately? Maybe you're a small outfit, or part of a huge enterprise with an entire strategy for brands and apps. But every enterprise needs to answer this question: Who are the people that use your apps--do you know your customer? Appboy specializes in that issue--and in many other aspects of mobile CRM, from getting messages out to users when a bug causes a problem, to integrating social network information for sharing, from customer feedback modules, to push messaging for special deals, and cross promoting with notifications and updates.
Podio is a web service that aims to provide a customizable online workplace. There are a lot of apps, and you can set up and position your dashboard as you please. However, sometimes the app you want isn't in the set. In that case, they also offer the Podio API to code your own custom apps for use within your Podio workspace.
