Catch is another idea manager that's well-suited to the Galaxy Note. You can create notes with text, voice, and images whether you're online or off, and add multiple images and voice memos to a single note. Catch can scan barcodes too--handy for remembering gift ideas. It automatically backs up notes across your Android devices, and to Catch.com's cloud service.
Want to work collaboratively? You can create a shared space in Catch and invite friends and colleagues to add their notes and ideas. The free version comes with three spaces (private or shared), and lets you save 70 MB of new content each month to Catch's cloud service. Pro and Premier plans are available as well.
