Still the best
     
by Brad Henry · March 5, 2019

I’ve been using a different outliner app for a while because I’ve been sort of forced to. Recently I missed this one so much I switched back, it felt so good to use it again. Efficient display of information and can quickly edit and move things. Love it.

Love that it works on all devices (ipad, mac, iphone)

Very good outliner that syncs and works well on all devices. Optimized for touch devices, but servicable on desktop. Keep up the good work!

Best Outliner App
     
by Ex_Palm_Loyalist · January 26, 2023

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.

Excellent outline app

I have used this app for a number of years and it stays on all my devices and is used constantly. If you're looking for an outline app this is a must for you!

Passcode

Definitely need a passcode option.

Feature Suggestion
     
by BethWCox · August 6, 2019

One feature I’d really like to see is a “New list from checked”. This is my main list app. I use it for shopping, packing, etc. For shopping, I’d really like to keep a main list, check off the items for that day, and then create a new shopping list from just the checked items. That’s the only thing keeping me from a 5-star rating.

I’ve used this app for many years. Super easy, super flexible, and dead simple. Full print, export, import. Can’t say enough good about it.

Unclear on the concept
     
by silly redux · October 1, 2020

The app provides for the use of tags. I had intended to make an outline of a project and use tags to identify resources and people for each item. The developer just told me that tags can only be applied to a WHOLE outline, not individual entries. Makes the app useless for my purpose. Why tag a whole outline when you have a title. Support, when explaining this limitation asked. “Does that make sense?” Well...no.
