Like all CoolApp messages, voice and video calls are private too. You will be prompted to grant the Camera and Microphone permissions the first time you make or receive a CoolApp call.

Here’s how to start an encrypted one-to-one voice or video call:

1. In CoolApp, tap or to view your CoolApp contact list.
2. Select a contact or enter a number to open that conversation.
3. Tap the phone icon to start a voice call or  the camera icon to start a video call.
4. On some devices: Select Call in the prompt or the green Start Call button.
5. While on a call, tap the camera  to show or hide video from your side of the call.
6. Your call screen will show
   • Calling or Connecting – while waiting for the call to connect with your contact.
   • Ringing – when your contact’s phone is online and ringing.
   • CoolApp + timer – after your call has been answered.

Note: CoolApp Android users can adjust the size of the call tab navigation bar within CoolApp Settings > Appearance.
