It also supports creating photo journals by inserting images into your notes. Your notes can be: - Organized by attaching them to a calendar. - Sorted and stored in a hierarchical folder structure. The app also includes a shared calendar feature that allows multiple users to edit the same calendar collaboratively. In addition to text notes, you can manage photos, videos, music data, and web pages in the same folder hierarchy, each with its own comments. You can automatically play videos or music stored in a folder, with customizable playback order and repeat settings, and even transfer music files to your Apple Watch for standalone playback without your iPhone. The app also allows you to extract audio from videos, such as screen recordings, and compress and save it as music data. Data Pocket also provides powerful features such as full-text search across all notes, text editing utilities, and automatic text recognition (OCR) from images. Furthermore, text notes can be displayed with automatic scrolling or viewed directly on your Apple Watch. Additional features include RSS news feed integration and options to customize button layouts and the startup screen appearance, among many other useful tools.
