Doodle is a free online scheduling app that can quickly and easily poll the availability of the people you need to gather for both your business and social life instead of sending email messages or making phone calls.
Doodle lets you suggest several dates and times and allows your contacts to indicate which work best for them. Users who initiate the event must register for a free MyDoodle account, but your contacts don’t need to register in order to indicate their scheduling preferences. Once you’re signed up, you can connect your calendar and keep track of all of your meeting requests. Doodle mobile lets you Doodle on the go.
