TabNote is an iPhone application designed for creating colorful notes akin to sticky notes. With a palette of 10 colors at your disposal, you can customize notes to your liking. The app allows categorization of notes into tabs for easy organization, making it convenient for managing tasks related to shopping, work, and daily affairs.

The app automatically adjusts note sizes based on content length, optimizing screen space for efficient viewing. Users can switch between two or three-column grid views or a single-column list view. TabNote features a notification function for setting reminders and to-do lists, offering date and time specifications with recurring options. Additionally, users can attach photos to notes, choose from a photo library, lock important notes with face, fingerprint, or password authentication, search notes by keyword, and access various customization options like text size and theme colors.
