TooDo handles a very simple task, i.e. managing todos, but it does that in a smart way, with ergonomics considerations in mind. Here a list of features that TooDo supports.

• Geographically-based reminder notifications by tracking down the Android device location in real time
• Contextually-based reminder notifications when the end-user switches his current context and that a todo matches with that context
• Emission and reception of todos with a complete workflow to one or multiple recipients, via SMS. GTalk is not supported any more
• Two-way synchronization of TooDo todos and categories with the tasks and lists of the "Remember the Milk" service
• Two-way synchronization of TooDo todos and categories with the tasks and folders of the "Toodledo" service
• Supports quick notes: textual, audio, video
• Creation/edition of todos through a rich user interface
• Classification of todos through categories, which propose default behaviours to todos
• Filtering and search of todos
• Various reminder notifications through sound, vibration, led. All notifications can be suspended for a while
• Fully internationalizable (this is not possible for the moment in Android, but all texts are not "hard-coded")
• Extensible for synchronization to any task manager web service (provided its makes and API available)

In addition, TooDo is totally free of use.
