iOS App Settings and Toggles


This article outlines all of the options and settings available in the iOS Zello application. Any settings changes that are made will only impact the device on which they are made.

Starting Screen

  • Sign up - Create a new Zello account for free or Zello Work. 
  • I already have an account - log into an existing account (free or Zello Work)
    • If Zello Work is chosen, a new field for the Network name will be displayed. Additionally, an option to scan a QR code for login is available.
  • Zello Work - Log into an existing Zello Work Network

Invite Coworkers Screen

  • Upon initial login, the user is presented with the option to invite coworkers by email or by SMS
  • Full name and email address or cell phone number with country code are required.


  • The menu is accessed by tapping the 3 horizontal lines (hamburger menu icon) in the top left corner.
  • Username with network name and picture (if one has been added) is seen at the top.
  • Accounts - clicking this option will display all of the accounts which have been logged into on the device. This is provided for quicker account switching. Swiping from left to right on one of the account names will give the option to delete the account from the device. The Plus icon in the top left will give the ability to log into a new account (free zello or zello work). The check icon indicates which account is currently active.
  • Status - the status indicates the current status of the user. Tapping it will give the option to manually set the status, as well as enter a custom status message. The toggle switch at the bottom gives the ability to set whether status is changed to Available when the talk button is pressed.
    • NOTE: Status cannot be manually changed if the network administrator has turned on Status Lockdown in the management console.
  • Recents - Brings you to the Recent conversations page. This will display both recent channel conversations and direct conversations. The small plus icon in the top right will give the ability to create a new Ad Hoc group conversation with one or more users.
  • Contacts - Tapping this will bring up a page showing all of the direct contacts available to the user. Each user is shown with the Username, Picture, and current status. The invite button allows for inviting new coworkers, and brings up the same screen mentioned above.
  • Channels - Tapping this option will bring up the channels which the active user is a part of. Each channel is shown with the name and how many people are actively connected. If there is a power icon to the right of the channel name, this indicates that it is a Dynamic channel, and allows the user to disconnect (if it’s green) or connect (if it’s grey) to the channel. Tapping a channel name will bring the user directly to the talk screen for that channel.
  • Options - Tapping options will bring up a list of settings that are available to the user that can be changed for the device they are using.


  • Audio
    • Record over bluetooth - toggle - This setting must be on if a bluetooth device is being used, and has a built in microphone that the user would like to use. If it is off, the microphone in the BT device will not be used to record messages. When turned on, this brings up an additional setting called “Play as phone call with Bluetooth”
      • Play as phone call with bluetooth - this option uses Hands Free Profile (HFP). Select it if your bluetooth device does not support Advanced Audio Distribution Profile (A2DP).
    • Mix With Other Audio - Allows audio to be played at the same time as audio from other apps such as music.
    • Noise Suppression - Reduces background noise when sending a message
    • Amplification - Recording and Playback amplification can both be set to automatic or Manual. If set to manual, the Gain and Microphone Boost (only for recording) can be adjusted with a slider.
  • Alert Tones/vibrate - This section allows the user to set the volume for alerts, as well as turn individual alerts on or off. Alerts can be customized if the user would like to hear a different type of alert tone other than the default one. Alert vibrations and visual alerts (notification banner) can also be turned on or off.
  • History
    • Delete Messages - Allows the user to set how long messages are retained on that device in each conversation history.
    • Save sent images to “photos” - If this option is on, photos that are sent from the device will automatically be saved to the Photos app.
    • Current account history - shows message history and image history in bytes and allows the user to delete the history for the current account.
  • Push-to-Talk-Buttons - provides the user to specify how the on screen button functions (hold-to-talk, toggle, or disabled). Hold to talk requires the user to continually hold the button in order to send a message. Toggle requires that they press and release to send, and then press and release again to end the message.
    • If a user would like to add an accessory button, whether on the device or from a wired or wireless accessory, they would click “Add New Device”. The app will wait and prompt the user to press the button. Once it recognizes the accessory, it can be customized just as the on screen button, as well as to trigger a specific contact or channel
  • Themes
    • Provides options to change the appearance of the Zello application. Users can choose from Light, Dark, or the ability to match the system appearance
  • Support
    • Help - This will bring the user directly to the Zello Support Center and Knowledge Base
    • Report a Problem - This will allow the user to send a problem report to Zello Support. There is an optional text-box for the user to provide a description of the problem
    • Advanced Settings - A description of these settings can be found in the iOS Management Console Settings article
      • Use TCP only (mobile connection)
      • Keep alive interval (mobile connection in seconds)

Talk Screen

While very similar to the Android application, the talk screen on the iOS application differs in some small details. Here is an overview of that screen, with screenshots.

  • Message History - Tapping the small speech bubble in the top right corner will bring you to the message history for that channel or conversation. This is also where you will be able to send text messages
  • The channel name and number of actively connected users is listed at the top. In the picture on the left, we see the channel name "Everyone" and 1 person connected.
  • In order to send a picture, tap the camera icon directly below the channel name on the left.
  • The large button in the center of the screen is the record button. By default, you will need to press and hold this button to start recording, then release the button to stop recording.
  • The icon in the bottom left corner will allow you to choose a speaker or bluetooth device to play to. Use this if you have a headset or speaker mic you would like to play to.
  • At the bottom of the screen in the center, you will see the status indicator. Tap this to change your status, or press and hold it to pull up the Status page, where you can set a custom status message and choose the status you would like.
  • The icon in the bottom right hand corner shows the current connection status of Zello. Tapping this icon will bring up a connection quality message at the top of the screen


Tapping the downward pointing arrow at the top of the screen will show the following menu

  • Set as default will allow you to pin this channel to the menu. The default channel or conversation will be opened each time the app is launched.
  • Add to favorites displays an orange star next to the channel name. Favorite channels are then shown at the top of your channel list in the channel menu.
  • Mute Everyone will prevent messages from audibly playing when received, and will save them in the conversation history for playing later.
  • Send location allows a user to send their current location to every member of that channel. The location is then sent in the conversation history page, where it can be accessed by any channel member.
