-= Recent version history =-

Version 3.8
• Open In... support
• Ability to hide the outline list on iPad
• Minor UI tweaks

Version 3.7
• iOS 9 multitasking support
• One-tap access to notes on iPhone. To enable this, some UI was shifted around. The item chevron is gone, replaced by the "item info" toolbar button that previously only existed on iPad. The delete button was removed to make room for this, so swipe-to-delete is the only deletion mechanism.
• iOS 8.0 or higher is now required

Version 3.6
• Added zoom to focus on a single subtree
• Support for iOS 8 and the new iPhones

Version 3.5
• Automatic sync

Most used Ap


This is the Ap I use everyday, and the one which I wouldn't do without. I used to have ListPro on a Windows phone for To Do lists, and wanted something similar for iPad and iPhone. I chose Outliner because the software allows you to nest items and it is easy to indent them or to move them up or down without the need for complicated menus. The software doesn't try to organise you: it is a tool. Simplicity is its great virtue. I was able to import existing lists from ListPro with considerable ease. I have found myself using Outliner not only for lists and outlines, but also for taking notes - I just find it easier to use than some of the dedicated programmes designed for note-taking, and it is easy to reorganise material afterwards.
I use this Ap everyday, and can't rate it highly enough. It synchronises to a web version which, although clunky, means that you have access to your material wherever you have access to a computer. Also, it makes keeping everything synchronised across devices is easy. You used to have to remember to synchronise, but the latest update does it automatically - a great improvement.

Even better...


I have always liked this app but now with web-syncing it has reached a new level. My iPod Touch is (through no fault of any apps) a little flakey requiring more rebuilds than the Six Million Dollar Man. Every time I rebuild, I lose my apps and data. For those apps that did not have web-syncing I simply lost data, a real pain, and that happened to me several times - no fault of the apps, just the iPod Touch. Web-syncing is a way the developers are able to make up for the shortfalls of the iPhone software. For me it is a demonstration of a developer's commitment to their customers: whilst Apple is working on getting their software more stable, the developer provides a way of minimising inconvenience due to failures which are not the developer's making. Rather than saying "this is not our fault - speak to Apple" they are saying: "whatever the reason for the iPhone's issues, we want to make the user experience easy for you". Web-syncing makes my life easy - so thank you CarbonFin folks - if I had not bought the software already, the web-syncing would certainly have done it for me.

Expandable tree navigation


This expandable tree navigation style of a task list application is much quicker to locate relevant tasks as opposed to sideways scrolling screens which all the other task apps use. For this and the fact that it's easy to re-order tasks around I give this 5 stars.

I would like to see Outliner take on a couple of iPhone specific navigational features such as left swooping a task to reveal a red delete button like it does on iPhone Mail for example, and a feature that once a task is highlighted a further click would expand or go to the task properties similar to iPhone Calender.

I can't give any more than 5 stars since I've tried and paid for so many other task apps and this is the one I now use, but if I were writing this app I would include the above navigation features - good work CarbonFin
