Notepine is an iPhone app that builds note trees. Notepine allows you to take notes and organize those notes within a tree-like hierarchy. It was designed to be your all-purpose personal information manager.
Notepine provides tag, filter, search, and sort capabilities for each level in your hierarchy. Use it as a personal database of tasks, key dates, or movies you are interested in.
Notepine provides note aliasing. Use this to organize your notes into multiple hierarchies.
Notepine provides a relationship feature for interlinking notes. Use this to create dynamic organization charts and family trees.
Notepine can work locally or in iCloud. Share most notes with your other devices, but keep sensitive notes securely on your local device only. Notepine takes advantage of iOS data protection, if enabled.
Notepine notes are each universally unique, and can be exported and imported through email messages. Share your notes and your hierarchies with your friends.
Notepine was designed for content creation. Use it to take notes in class. Use it to write a story. Use it to write a book. Or just use it, when you are out for a walk, to quickly write down that random thought that you don't want to lose!
