# How to create a conference
With TrueConf for iOS/iPadOS application, you can schedule or create ad-hoc meetings in one of the four modes: all on screen, smart meeting, moderated role-based conference or video lecture.
Go to the Conference → Meet now section, enter the meeting name and select the conference mode in the settings.
If you select a smart meeting or a moderated role-based conference, it will be possible to specify the number of vacant spots on the podium. Use the Number of presenters and participants slider to select the correct number. To learn more about smart meeting mode, read the TrueConf for Windows user guide.
When you join a meeting by calling its owner, the owner receives a corresponding request by default. You can change these settings by enabling the Automatically approve join requests. In this case, a user who wants to participate in the meeting will automatically connect to the meeting when calling its owner.
To make sure that new participants can always join your conferences without asking for permission, go to Options → General and activate the switcher Accept new participants automatically.
To make sure that participants join the conference with their cameras and microphones turned off, activate the following switchers:
- Mute participants on entry
Stop participants' video on entry.
Next, tap on the Create button to start the conference. Participants will have to be added during the conference.
