I tried [URL="https://itunes.apple.com/us/app/any-do-to-do-list-calendar/id497328576?mt=8&at=10l3Vy]Any.do[/URL] and [URL="https://itunes.apple.com/us/app/todoist-organize-your-life/id572688855?mt=8&at=10l3Vy]Todoist[/URL] that have a lot of great functionalities.
I have also tested [URL="https://itunes.apple.com/us/app/microsoft-to-do/id1212616790?at=10l3Vy]Microsoft:to-do[/URL] but I am still staying with Wunderlist (for now) because I cannot find an equivalent to [URL="https://itunes.apple.com/app/id1205902510?at=10l3Vy]Wunderlist: Quick Capture[/URL]
This app helps me record my thoughts in the least amount of time possible and I have to do this very often during meetings or even conversations. With the other apps the process of creating a new task is often too long and end up procrastinating and at the end of the day forgetting to create my note ....
So maybe I should open a thread how to replace Wunderlist:Quick add
If you do not have the need to create task on the spot, then Any.do or even [URL="https://itunes.apple.com/us/app/microsoft-to-do/id1212616790?at=10l3Vy]Microsoft's To-do[/URL] may be a good alternative
