Frequently Asked Questions


What devices and platforms does Gruveo work on?

Gruveo works on the following devices and platforms:

  • Desktop or laptop – via web browser on
    • Chrome, Firefox and Opera on Windows, Mac and Linux
    • Internet Explorer 10+ on Windows with Temasys plugin installed
    • Safari 7+ on Mac with Temasys plugin installed
  • Android phones and tablets – via a native app as well as web browser
  • iPhone, iPad and iPod touch – via a native app

Why can't I use Gruveo in Chrome/Firefox/Opera on iOS?

Third-party browsers on iOS have to use Apple’s browser engine which does not currently support the WebRTC technology required for Gruveo to work. However, you can make Gruveo calls on iOS with our native app. Click here to give it a spin!

What is the difference between anonymous and direct Gruveo codes?

An anonymous code allows anyone to make a free Gruveo call without having to create an account. As long as two people enter the same anonymous code on Gruveo, e.g. “banana13”, they get automatically connected to each other.

A direct code begins with @ and belongs to a specific user, e.g. @hello. Direct codes work like phone numbers: The code owner receives a ring every time someone enters their code on Gruveo. You don’t need to create a Gruveo account to call a direct code, and that makes direct codes a perfect solution for making yourself easily available to your clients, customers, or friends. Click here for more info on direct codes.

What if a 3rd person connects under the same anonymous code while I'm talking to someone?

Gruveo is a one-on-one video calling service. After a call between two parties has been established, nobody else can join that call. A third person who connects under the same anonymous code will get a “busy code” message and will have to try again later or choose a different code to connect.

Can I make group calls with Gruveo?

We are working on making group calls possible in the near future. Meanwhile, all Gruveo calls are limited to two participants.

Are Gruveo calls secure?

Yes. First, all calls on Gruveo are encrypted end to end with industry-standard encryption. Second, wherever possible, Gruveo calls are established using decentralized, peer-to-peer technology where audio and video flow directly between the users’ devices. (Text messages are relayed via our secure servers.) And third, once a call between two parties has been established, no other party can connect to it, even if they enter the same code.

Gruveo Pro

What is Gruveo Pro?

Gruveo Pro is our premium subscription that offers extra features for business and power users. Click here to check what’s included.

I am a Pro user on a call with a non-Pro. Can the other party share their screen, too?

Absolutely! Screen sharing is available to all call participants if at least one of them is a Pro.

As a Pro user, will screen sharing only work in calls on my direct code?

No, Pro users can share their screen in all direct and anonymous code calls provided they are logged in to Gruveo.

What devices and platforms can I share my screen from?

Outgoing screen sharing, i.e. sharing of your device’s screen, is currently supported in Chrome and Firefox on Windows, Linux and macOS. In both browsers, you will be prompted to install a small and non-intrusive browser add-on to enable screen sharing in Gruveo. This installation needs to be done only once.

Incoming screen sharing, i.e. receiving of the screen sharing image, works across all of the Gruveo’s supported platforms without any additional steps.

What are the branding images that I can set as a Pro user? Where are they shown?

As a Pro user, you can set two types of branding images for your account:

  • Profile picture. This image is shown on the outgoing call screen to everyone calling your direct code. Use your photo or business logo to let callers know that they are in the right place.
  • Call background. This image replaces the standard Gruveo background for everyone calling your direct code, as well as for yourself. Use this image to reinforce your brand.

What kind of extended caller information is available to Pro users?

Gruveo Pro users get access to the following information about callers on their direct code:

  • Approximate location down to the city (determined from the caller’s IP address)
  • Referrer website or app, for example, Facebook Messenger and the like
  • Platform: Mobile or Desktop.


I am not receiving the confirmation link after signing up.

Please log in to Gruveo at, go to Settings and check if your email address is correct. If it is, please click “Resend confirmation” to have the confirmation link resent to you. If your email is incorrect, please click “Change Email” and change it to the correct one. You may also want to check your spam folder.

Can I delete my account?

We don’t support account removal at this point. You can still use Gruveo anonymously, so just log out of Gruveo on all your devices and forget you’ve ever had an account.

How do I make sure that call notifications are enabled on my device?

Ensuring that you have call notifications enabled goes a long way towards preventing missed calls on your direct Gruveo code. Click here for the details on how to make sure that the notifications are on.

Do I have to keep the Gruveo app open while waiting for the other person to join back on an anonymous code?

You don’t! You can close the Gruveo app on your iOS or Android device while waiting for the other party. If they join back within 30 minutes, you will receive a notification. Simply tap that notification to begin your call.

Make sure that background notifications are enabled for this to work. They always are on Android; for iOS, please see “Enabling Push Notifications in Gruveo for iOS” in this article.

I am getting a warning that says 'Your microphone may not be working.'

In modern Chrome, Firefox and Opera, Gruveo is able to detect when your microphone is not generating any sound (not even normal background noise). In such cases, Gruveo shows the warning asking you to check your microphone. Here are the steps to troubleshoot this:

1. Check your hardware

  1. Ensure that your microphone is plugged in and functioning properly
  2. Check that your microphone’s mute button isn’t on.

2. Check your system microphone level

Microphone Levels on a Mac
If you are on a Mac:

  1. Launch the System Preferences app
  2. Choose “Sound” and then click the “Input” tab
  3. Select your microphone from the list
  4. Move the “Input volume” slider all the way to 0 and then to about 75%.

Microphone Levels on Windows
If you are on Windows:

  1. Right-click the speaker icon next to the clock and choose “Recording devices”
  2. Click the “Recording” tab in the dialog that pops up
  3. Select your microphone from the list and then click “Properties”
  4. Click the “Levels” tab in the Microphone Properties window that pops up
  5. Move the microphone level slider all the way to 0 and then to about 75%.

3. Restart your browser

If the above doesn’t help, quit your browser and then start it again. Note to Mac users: Simply closing the browser window won’t work. Quit the application by pressing ⌘Q.

4. Restart your computer

As a last resort, try rebooting your computer and then starting the Gruveo call again.

I'm getting no microphone warning but the other party still cannot hear me.

Gruveo is only able to detect microphone issues in modern versions of Chrome, Firefox and Opera. If you are using Safari or Internet Explorer, it is still possible that there is a problem with your microphone. Please refer to the question directly above for troubleshooting.

If you are using Chrome, Firefox or Opera but are not getting the microphone warning, then the issue is probably on the other party’s end. Please ask them to do the following:

  1. Make sure that their system volume is not muted
  2. Ensure that their speakers are plugged in, turned on and are functioning properly
  3. If the above doesn’t help, ask them to quit their browser and then start it again
    • Note to Mac users: Simply closing the browser window won’t work. Quit the application by pressing ⌘Q
  4. As a last resort, ask the other party to reboot their computer and then start the Gruveo call again.

The other party hears an echo when I'm on Firefox on Android. Why?

Firefox on Android seems to have issues with acoustic echo cancellation. Try wearing a headset, or switch to Chrome or Opera which provide better sound quality on Android.

I am getting the 'Cannot access camera and/or microphone' message when trying to make a call.

Please make sure that your microphone or microphone-equipped camera is plugged in as Gruveo won’t allow you to make calls without a mic. If the microphone is OK, see if Gruveo has been permanently denied access to your camera and mic in your browser. Please check the next question for details.

I have denied Gruveo access to my camera and mic in my browser and now I cannot connect.

Allowing Gruveo to access camera and microphone in Chrome
If you are using a desktop version of Chrome, do this:

  1. After a failed call, a crossed camera icon will appear in Chrome’s address bar
  2. Click the crossed camera icon
  3. In the dialog that pops up, choose “Always allow to access your camera and microphone”
  4. Click “Done”
  5. A message prompting to reload the page will appear on top. Click “Reload”.

Enabling voice and video for Gruveo on Android
If you are using Chrome on Android, follow these steps:

  1. While in Chrome, press the Menu key on your device
  2. Tap “Settings”, then “Content settings” and then “Website settings”
  3. Tap the line that says “” and has a crossed camera icon next to it
  4. On the screen that appears, check the box next to “Voice and video”
  5. Exit the settings screens and reload the Gruveo page.

Resetting site preferences in Firefox
For Firefox on desktop, here is what you need to do:

  1. In Firefox, click the “History” menu item and then “Clear Recent History…”
  2. Select “Everything” in the “Time range to clear” dropdown box
  3. Make sure the “Site Preferences” checkbox below is checked
  4. Click “Clear Now”
  5. Reload the Gruveo page.

Finally, if you are using the Gruveo iOS app:

  1. Launch the Settings app on your iOS device
  2. Go to “General”, then “Reset”
  3. Tap “Reset Location & Privacy”
  4. Tap “Reset Settings” in the prompt that appears
  5. Restart the Gruveo app.

How do I make Gruveo use a different camera in Chrome?

Making Gruveo use a different camera in Chrome
In a desktop version of Chrome, do this:

  1. Initiate a video call on Gruveo (the code doesn’t matter)
  2. Click the camera icon in Chrome’s address bar
  3. In the dialog that pops up, select your desired camera in the “Camera” dropdown box
  4. Click “Done”
  5. Hang up and reload the Gruveo page.

Gruveo will now use the camera you selected for all subsequent video calls.

How do I switch between the front and back cameras in my Android browser?

The Gruveo web client currently doesn’t offer a way to switch cameras directly. Check out our Android app for an easy way to switch cameras, or try this workaround:

  1. Download Firefox or Opera for Android
  2. Start a Gruveo call in one of those browsers like you normally do
  3. To switch your camera during the call:
    • Turn off the camera
    • Turn the camera back on. Important: When prompted for the camera to use, select your device’s back camera
    • The other party will now see the picture from your back camera
  4. Repeat step 3 to switch from the back camera to the front one.

It is important that you use Opera or Firefox because Chrome does not prompt you for a camera to use and just assumes the front-facing one. Also, we recommend Opera over Firefox because it will be quicker to switch cameras.
