Appointment Scheduling App

Only a simple app. But i think it can be useful. Why you just can schedule appointments for yourself only? I like to have the possibility to create an appointment for someone else too. And the app should be able to choose the best date/time for the appointment.<br><br>For example: <br><br>I have a meeting with my friend. <br>1. I put the people into the app who have to be there <br>2. What is the meeting about? (Maybe the app can recognize how long the meeting will take)<br>3. The app should find the best date/time for the meeting.<br><br>The same procedure should be possible for other people/calendar's. Why you can schedule appointments only for yourself? I think it can be useful if you can make an appointment for someone else too.
