An Android application by Gina Trapani and the Todo.txt community designed to manage your todo.txt file stored in Dropbox.
Purchase Todo.txt Touch in the Android Market or download the apk, but be aware this app is in development and there are several known bugs and todo items.
Todo.txt Touch requires that you have a Dropbox account in order to be able to capture the todo.txt file elsewhere than just on your Android device. Eventually, we hope to support other cloud sources.
There are already a multitude of decent task managers for Android, but Todo.txt Touch is a minimalist, plain-text focused solution we built to learn by collaborating on Android development.
