Siri to todo.txt
Setup: create a "to do" list on the iOS Reminders app. Whenever you want to add an item to your todo.txt: 1) Tell Siri "Add to 'todo' list". 2) Wait for its response "OK, just tell me what you want to be reminded about". 3) Dictate your todo. It may take a while for the IFTTT iOS app to realize there's a new reminder, before it adds it to your list. That's it.
