Data Pocket is a versatile note-taking app that lets you easily customize text with adjustable font sizes, colors, and other formatting options using simple one-tap controls. 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. Starting from version 2.0, WebLink feature has been added, allowing users to view and create notes in this app from a web browser on a PC or other devices. We regret to inform you that, since then, features that require the use of server resources has been made available only as a paid option. To use it, a subscription or ticket purchase is required. Your use of this application is subject to Apple’s standard Licensed Application End User License Agreement (“Standard EULA”). https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Please note that there may still be some bugs remaining, and we cannot take responsibility should any issues arise. However, we are releasing it in the hope that it will be useful to many people, so we would be grateful if you could try it out casually at first. Enjoy utilizing this app and make the most of it.
