CheatSheet - Liquid Glass Notes

CheatSheet is a free, open-source app for Mac, iPhone, and iPad for keeping short coding notes, command references, and checklists close by.

Create and search plain-text notes, choose note colors and fonts, and pin one note to a small, medium, or large widget. Note previews and widgets display headings, bullets, and checklist items. On Mac, the menu bar provides quick note capture and access to recent notes.

Notes are stored locally, with no account or internet connection required. Deleted notes can be restored from Trash for up to 30 days. The app is available in English and Spanish and is published under the MIT License.
