Find Your Notes Fast!
Search using terms and/or tags. Term/tag auto-completion and keybooard suggestions minimize typing. Searching for "word" automatically matches "words", "worded", "wordy", etc. (English only.) Search results ordered with best matches first. Supports Siri Search. Multiple search terms are easily distinguished by highlighting with different colors. When not searching, most recently modified notes are shown first.
Repeat previous searches with two taps. Instant acces to 'favorite' or recently viewed notes. No need to format your text: bold headings and subheadings are automatically styled (or use Markdown syntax for greater control). Syncs to all of your devices via iCloud; also, automatically backs up to iCloud. One tap access to next/previous note. Built-in viewer for attached PDFs. Search within long notes and PDFs. Drag-and-drop support (requires iOS 11).
Power User Features
Optional hierarchical tags. Logical AND, OR, NOT, and BEGINS-WITH for tag and term searching. Action sheet support for creating new notes or appending to favorites from within other apps. Text file import. Back up (archive) and restore any subset of your notes. Slide Over, Split View, and 3D Touch support. Easily handles thousands of notes. Automation via x-callback-url support and Siri Shortcuts.
Note editor automatically gets text from the clipboard when creating a new note. Can attach PDFs or images (e.g., manuals, technical papers, photos, screenshots), insert checkboxes, bullets, current date and time. Can easily add, remove, or rename tags across multiple notes. Notes are plain text, not a proprietary format, so your data is not captive and easily exportable exactly as you entered it. You can reset and rebuild the notes database from any full back-up.
