iPhone Developer Lisa Coumont has released aptodo, a simple, location-aware task manager for the iPhone and iPod touch. Unlike most other simple to-do list applications, aptodo organizes tasks by location and uses the iPhone and iPod touch location services to help identify which tasks can be performed in relation to the user’s current location. Tasks are organized into lists which are in turn assigned to one or more places. Users can then quickly determine which tasks are available to them based on their current location, or can choose to display a map of their places and tasks by turning their device into a landscape orientation. Aptodo is available on the App Store for $2.
