Catch is a service, similar to Evernote, that allows you to capture notes, photos, voice memos, and more and then access it anywhere. You can use the iPhone, iPad or Android app or access it through the web. Data is synced on your device so you can access it even when offline. They have browser extensions for clipping web content also (Chrome, IE, Firefox).
The free account is pretty powerful and offers the mobile notebook and journal, text, web clippings, photos and voice memos, 3 streams and 70MB per month of content uploaded. You can even Geotag your notes.
You can also upgrade to paid accounts to add brainstorming and conversations, along with increased streams and data upload amounts.
A stream is a way to group different data (notes, photos, etc) into a topic to keep them organized.
You can share your content with others, or keep it private. They also have Catch-U, a help site that can help get you started using Catch.
You can create a free account or login using Google or Facebook.
Catch seems like another great way to collect and organize data and notes.
