ChromaticLove is a simple API proxy for Instagram. It's currently a free service and is the easiest way to add your Instagram pictures to any website without exposing your Instagram credentials to the web.
With revision 1.1 of SignalFlare, we launched a simple web service to share GPS coordinates called sgnl. It takes a latitude and longitude and returns a device-appropriate link to a map. Right now, it supports iOS & Android, but will support other options in the future.
We have a few other apps in the pipeline, so subscribe to our blog or follow us on Twitter if you want the latest and greatest.
