Outliner for iPad ٤+

My favorite feature is that it keeps copies in synch, so the shared checklists are always up to date on whatever devices they live on.

A nice to have feature would be to mark a task as in progress but not yet complete. The workaround is just to leave the task open and use notes for progress. One can also micromanage by splitting the task down into two or more sub tasks.

Another nice to have would be counts of how many tasks are in the outline, just informationally.

NEW CAVEAT: There is a setting to make font smaller, but not one to make it larger or even largest. Nowadays my vision won't let me work without a bigger font. Developers need to give more thought to accessibility. -- ORIGINAL REVIEW (5 STARS): OmniOutliner is prettier and offers columns, this outliner lets me get real work done fast. It's easy to make and rearrange an outline, and it works with both email and the developer's free online syncing service. Easy to get data in and out with OPML. I actually use OmniOutliner, too, but for specific purposes involving highly formatted documents I create on my Mac. For serious thinking and outlining on the go, whether on my iPad or iPod, this is what I prefer to use, because it gets out of my way and lets me work. Also let's me organize my outlines with tags, which I can treat like folders. Wishes? Dropbox support would be nice. UPDATE: The addition of Dropbox support has been very helpful. Unfortunately, one must opt for Dropbox support on a file-by-file basis, and the syncing is not automatic. Still, it's pretty easy.

This is the longest running app I’ve had. It’s so simple and it’s become a part of the way I think. I have other outliner apps and they simply get in the way. Yes they have lots of other bells and whistles but nothing comes close to the simplicity and straightforward way this app works.
Completely recommend this to anyone, and the web interface is icing on the cake. Great stuff.
