This app is wonderful! It has enough levels (instead of the other's two or three) to really organize your thoughts. It was invaluable to me while I was in school. And when I had to reset my phone, and thought I lost all of my outlines, I contacted Outliner and Freddy was immensely helpful and took the time to solve the issues.

This is the 2nd or 3rd time I downloaded and tried Outliner, but until now I couldn't get past those huge 3D buttons. This time I purchased the Pro version (only $5), then wrote the developer to ask for smaller buttons. People - if there is something in this app that is holding you back, I urge you to contact Freddy (yup, we're on a 1st name basis now). You will not be disappointed. Update: 2 years later and OutlinerPro is still my workhorse app. Reliable - no weird crashes to corrupt data.

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.
