I never updated my review after Google sync was implemented. Thanks! The developer is very responsive & put up with a lot of my nagging questions. This is one of the first apps that I ever bought & still one of the best. One more wish list item: it would be great to set a specific time for a due reminder. I can currently only choose the calendar day. But this is just a minor note. I'd give the app 6 stars if I could.

I was never able to create useful outlines until outline programs/apps became available. Finally, I was able to restructure hierarchies without tearing up each draft. They are very useful in capturing unstructured ideas, and then forming them into logical structures. My favorite was, and continues to be, ECCO PRO, a discontinued Windows program. Unfortunately, no one has reverse engineered ECCO PRO to run on Android devices, such as my cell phone. This "Outliner" is the best Android substitute I could find. I often reccomend it to others.
