A "hierarchical spreadsheet" that is a great replacement for spreadsheets, mind mappers, outliners, PIMs, text editors and small databases.

Comment summary: TreeSheets is praised for its flexibility and unique features that combine mind mapping, spreadsheets, and outlining. It is particularly appreciated for its ease of use, with an understandable tutorial that aids quick adoption. Users enjoy its ability to handle nonlinear notes effectively, although some wish it had more polished features, a dark theme, and support for RTL languages. Despite lacking certain functionalities like a calendar and Android compatibility, it remains a valued tool for structured information storage.

Extremely well thought out app, very different from almost anything else out there. Would be nice to get more active developers on it again. Though its fully functionally currently.

It does not support RTL (Right-to-Left) languages.

Best mind mapping app i used in Windows, it have a understandable and useful tutorial it makes it quite easy to learn the app and use it. You can understand the app and start to use it comfortably fast thanks to app's well thought tutorial.

It's only downside can be the abscence of the dark theme but you can have a dark theme by simply painting table and background a dark color.

TreeSheets does not have a calendar and it does not work on Android. Therefore, it is NOT an alternative to EssentialPIM.

I am a fiction writer, and this program is like having a plot board on steroids. It is like a mind mapper, spreadsheet, outliner and tagger in one. Nothing else I have seen comes close!

Great way to store information in a structured way. Though I do wish the spreadsheet features and embedded images were more polished.

What is TreeSheets?

The ultimate replacement for spreadsheets, mind mappers, outliners, PIMs, text editors and small databases. Suitable for any kind of data organization, such as To-do lists, calendars, project management, brainstorming, organizing ideas, planning, requirements gathering, presentation of information, etc. Its like a spreadsheet, immediately familiar, but much more suitable for complex data because its hierarchical. Its like a mind mapper, but more organized and compact. Its like an outliner, but in more than one dimension. Its like a text editor, but with structure.
