Best overall of the many I tried. My "go to" "to do" app – Outliner Review

Love this app! And I am not easily pleased. The focus feature is HUGELY beneficial and not matched by others I have tried. Worth having this app for this feature alone. As an avid outliner user for projects and to do lists, I find this is the most stable, feature appropriate, and easy to use of the many outline apps I have used on my iPhone 6 and two iPads. Syncs quickly and accurately. My only three additional requests from Carbonfin would be (1) notes, (2) a night mode and (3) a Mac app, however the web version is adequate for me. Of course I would prefer more than "adequate." Though my second and third too choices for iOS outliners have one or more of these features, this is still my preferred everyday outliner because it is just that superior. Though there is room for improvement its utility still ranks above the others plus the developer is continually upgrading therefore I give it 5 stars.
