Setster is compatible with the .ics file format. If you use calendar applications like iCal, Google Calendar, IBM Lotus Notes, Outlook, and Yahoo!, you will receive appointment confirmations with the time and details directly into your calendar.
There is nothing you need to do. Once you’ve accepted an appointment, we send the .ics file with all the appointment information to both you and your client.
Some calendar applications will default to automatically insert those .ics files and details into your calendar for you. Some calendar applications require you to take an action, like save the file. Once the item is in your calendar, it will look like every other appointment or busy spot in your calendar.
