Is Outliner legit?
✅ The Outliner app appears to be high-quality and legitimate. Users are very satisfied.
I’ve used it daily for over a decade now. There’s simply no better app for nestling lists within lists within lists. Now, I wouldn’t say it absolutely needs an Apple Watch companion app but it sure would be awesome on the watch.
Super Multi Use App
I have used this app, and relied on it, for many years. I just count on it so much, it’s a part of life for me. It keeps my lists, checklists for when I have to travel, outlines for classes I teach, etc. Super features for me: Easy movement of whole outline blocks, simple to do and without the complicating logistics of other programs The ability to access outlines from ipad, iphone and the web. Easy export Just puts from my knothole. Thanks a ton for keeping this going.
I wrote this review several years ago and my opinion hasn’t changed a bit!!
Love This Outliner App
It’s so incredibly simple fast & easy to use. Elegant software at it’s finest!
Best Outliner App
Great for all kinds of outlining. Also great for Goal tracking and other aspects of linear time management. Excellent integration with Dropbox and seamless text exporting. It is not perfect, but it is a minimalist app which perfectly handles outlines.
Perfect again!
Let me start by saying I love this app. I’ve reviewed it with 5 stars before but I’ve recently ran into a problem. I use Dropbox to sync my OPML files and this has worked flawlessly for a long time. However, I had to create a new Dropbox account a few days ago due to a lock. This meant I had to re-connect apps that relied on the platform to Dropbox from scratch. Outliner was one of those apps. Unfortunately, a few hours after authorizing the app, Outliner threw a sync error asking me to re-authorize. I did so thinking it was a fluke. However, this kept happening every time I used Outliner thereafter, the app kept asking me to re-authorize. At first, I thought this was an issue with mine alone or my Dropbox having a problem. However, upon researching, I found that Dropbox have updated their API with short-lived access tokens that expire in 4 hours time. According to Dropbox team, the app itself needs to be update to make use of permanent tokens if one wishes to authorize access once and have syncing without interruption after. And so I’m asking the devs here. Please update the app to correctly sync with Dropbox once more. Since there aren’t many cloud storage services available to use for syncing, users are limited on their choices and the buggy behavior slows workflow a lot besides being plain annoying.
Edit: just like that it’s back! Much thanks to the good folks at CarbonFin for fixing the Dropbox issue. Now it syncs perfectly like it did before. This app is indispensable!

My go-to app for personal, business & university teaching. Intuitive and easy to use.
One small suggestion: If there was a way to put projects into folders such as home, business, School, etc. as they say in Texas “I’d be in Hog Heaven!”
