Big Board is a tool that consolidates point-in-time events from collaborative work environments, chat services, calendars, and other apps into a single analytical display of cumulative activity. It can be used for project management, understanding team workflow, and as a launchpad for work. In order to connect custom applications, developers working in PHP can use the Big Board SDK to create a simple interface to the Big Board API. Installing with Composer is recommended for fluidity of use. The API is made accessible for Big Board users who obtain an access token after registering their custom application.
Guerilla Mail is a simple idea with one purpose: to avoid spam. The idea is dead simple: go to the website, it gives you a random e-mail address that's good for one hour, and links to nothing else.

For those cases, one might want to look into using the Guerilla Mail API.
The Transit App, an application that provides commuters with real-time transit information on iOS, makes its Transit App API available to developers who may want to integrate the functionality with other applications. The app has already been widely downloaded and received positive customer reviews, and filling the gap that was left when Apple removed transit from its own Maps app, it seems to be a really useful tool for anyone who relies on public transportation and the ability to get accurate and timely travel information.
