SheetPlanner
Organize. Plan. Do.

SheetPlanner is a powerful macOS 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 Dejal, under contract for SheetPlanner Software LLC. To find out more about Dejal's consulting / contract programming service, visit the Dejal Consulting page.
