For sometime, I have been experimenting with various productivity apps on the Play Store. I want an application that allows me to enter my to-do's, meetings and other notes. An important consideration is the ability to quickly add a task off the cuff i.e. not too many menus etc. Any suggestions for such an application are greatly appreciated, especially if you can tell me how you use it on a day to day basis. I am really expecting some gems from you, people!
