Started using this for work to keep my stuff scraped in a pile. Am now using it for To Do Lists and such at home. Has a lot of capabilities including attaching pictures, creating checklists, synchs with multiple devices, etc. I have Android devices...not sure about iJunk. Its called "Evernote". Not designed with fishing or hunting in mind, but I think it'll do. I intend to give it a shot this year.
