DataPocket by NACALMO

DataPocket is a memo creation app that allows you to easily adjust text color, size, and other text formatting with a single tap.

You can:

Organize and save your memos in a folder hierarchy
Attach memos to a calendar for easy management.

The app also features cross-text searching and string manipulation tools.

In addition to text memos, you can manage photos, videos, and web pages in the same folder hierarchy. The app allows you to automatically play videos in sequence within a folder and display images with comments in a tile layout.
The app includes automatic text recognition and extraction from images. It also offers features like auto-scrolling of text memos and the ability to display them 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.
