Telegram Bot API allows to create bots with AI capabilities such as teaching, broadcasting, and connecting. To include developers who work with Python language, Datamachine created an unofficial SDK, which provides installation, documentation, and quick start. See more of what the documentation could do for a development project at http://pythonhosted.org/twx.botapi/
Shoudio is an amusing iOS application made to tag places with audio snippets. These can be anything a user imagines, and a lot of fun could be had with this. For example, integrating this into Geocaching could be a lot of fun, allowing things like audio hints to help Geocachers find the cache. However, the developers of Shoudio didn't want it limited to just one platform, so they released a Shoudio API to allow clients for other platforms, and fun mashups.
Localscope, the app that:
"lets you see and know your locality like never before," now "enables third party applications to use the Localscope app to search for and discover geo tagged information via the Localscope API."
