I'm pleased to announce the release of a new macOS app: SheetPlanner. This is a powerful new app that combines an outliner, todo, spreadsheet, timeline, calendar, and more, enabling you to easily plan projects, manage tasks, organize information, and many other uses.

It includes support for multiple types of columns, inline notes and links, sorting, an option to focus on a subset of rows, flexible smart filter options, styles, dark mode, and many more features, yet is very simple to get started.

SheetPlanner was written by me over the past 18 months or so, as a Dejal consulting project for SheetPlanner Software LLC.

Start by picking one of the pre-made templates, or an empty document:

Configure columns, the theme, and other options in the Inspector:

You can show any combination of the Outline, Timeline, Month, Year, and Inspector views, in horizontal or vertical orientation:

And/or a year view for a heat map of tasks:

Include inline notes and/or attachments:

Customize powerful filters to show only matching rows:

Or edit the preferences:

SheetPlanner is available as a free download, and includes a free three-week full-featured trial. The app can be purchased for just $49.99, or continue with a free read-only mode if you're not ready to buy.
