Last.fm iOS and Mac OS X SDK is a development kit created Kevin Renskers. Using the SDK, developers can work with blocks, use only KissXML as a dependency, return values in correct data types, hook catching methods, and cancel operations. This kit is actively developed and maintained and used in the official Last.fm Scrobbler app. Other apps using Last.fm include MetroLyrics and Radio.com. Requirements to develop include iOS 4 and Xcode 4.4 or higher, an API Key obtained at last.fm/api, and Kiss XML.
The power of choice is a valuable part of our everyday lives, and with so many options at our disposal along with wildly different tastes and opinions, it's a good thing we have the freedom to choose. Based on this idea, it's easy to see how things like music charts, recommendations from film critics and general ratings on social media platforms may not be the opinions shared by everybody, and a recommendation system that could focus more on a person's specific preferences would be quite useful. That's pretty much what Tumbz has set out to do. The Tumbz API also makes it possible for this functionality to be integrated with other applications.
InviteBox, social referral program, allows merchants, bloggers, developers (and anybody else with a web presence) to refer friends and customers to recommended products. Users can take advantage of pre-determined referral offers (e.g. coupons, promo codes, free products, cash incentives, etc.) or create custom incentive programs. InviteBox offers all the needed moving parts from creating the referral program to implementation, and the analytics to measure success. Users can simply insert a widget into a website or utilize the Reward Callback API.
