This is OmniOutliner 5: a flexible, svelte, and focused app for creating, collecting, and organizing information and ideas. OmniOutliner Essentials is simple—everything you need to get started. Pro adds powerful features like smart columns, password protection, keyboard shortcuts, and plenty more. Try out both for free!

Use an outline to put structure on new ideas, rearrange them and construct beautiful documents for sharing with built-in themes. But it’s way more than just an outlining tool—you’ve got multiple columns, smart checkboxes, pop-up lists, and a fantastically rich styles system.

Draft a simple to-do list, create an agenda for a meeting, take notes, plan events, write anything from diaries to screenplays, or any other task that calls for structured text.


With the free two week trial, you can try all of the features of Essentials and Pro. After the trial, you can continue to use OmniOutliner to view documents for free.

Cannot believe the makers of omnifocus are behind this product

This outliner app is just clunky and awful compared to other Omnigroup products. Try editing an outline at all or dragging parts of the outline around. You just can’t. Or at least I couldn’t drag a subheading from one top-level heading to another. Also, Select all doesn’t work, but you can hold down shift and select multiple items individually? Not great to introduce friction into an outlining app.

I feel like I’m back in the early/mid-nineties when drag and drop wasn’t universal and people were just figuring out intuitive elements of the UI. For $10? No thanks. I’d rather outline things in Omnifocus, as silly as that sounds, but it’s actually way superior app for the task. Save your money and just get OF and export as taskpaper.

I love Omni Outliner. It makes writing things down somuch fun!

Needs some work


This used to be my main app of choice. I can’t tell you how often I would use OmniOutliner on my iPhone, iPad, or MBP as I worked two different jobs and traveld around giving presentations. It was useful for jotting my thoughts down, organizing a template for a lecture, making an agenda, using a checklist at a beer tasting, and more. Somewhere, however, OmniOutliner has lost its way. I just re-re-redownloaded the desktop app as I love what the company puts out (generally) and thought they’d make the app better. It’s January and the iPhone X doesn’t have a version yet. It was a hassle to get OmniPresence started (and it is too much friction to find the documents on any platform). I’ve had issues with exporting it how I wanted to (I’ve hashed that out in the past). But one thing that really bugs me is that suppose I create a style of a document with different levels having different settings. You cannot apply that style to the entire document. I’ve spent fifteen minutes trying to figure it out and I can only get it to apply one part (level 1) style to all levels.

Basically, it used to be a great product that, for some reason, has lost some of its ease of use, and now is harder to use than before. Pretty much any of the other outliner apps out there will serve you better. However, this is OmniGroup and I have faith in them. I’m not sure for why their 2017 was a year of going backwards in everything, but I’m holding out that 2018 will be their year to right the ship and return to the form of the company we all know and love.
