Google Duo Is Now Google Meet: How to Use the Unified App for Video Conferencing

Google Duo has officially transitioned and is now fully integrated into Google Meet. For users seeking video conferencing or person-to-person calling under the "Duo" banner, the current reality is a single, unified platform that combines the simplicity of mobile-first calling with the power of enterprise-grade meeting tools. As of early 2026, the standalone Duo brand has been retired, and all its core technologies have been absorbed into the Google Meet ecosystem.

The Merger of Google Duo and Google Meet Explained

The decision to merge Duo and Meet was driven by a need to simplify Google’s communication portfolio. Previously, Duo served as a casual, consumer-focused app for 1:1 video chats, while Meet was the professional tool for group conferences. By combining them, Google has created a versatile platform capable of handling everything from a quick "checking in" call with a family member to a 100-person corporate strategy session.

When you open what used to be the Duo app on your mobile device, you will notice the icon has changed to the Google Meet "four-color camera" logo. Inside the app, you now have two distinct ways to communicate: "Legacy Calling" (formerly Duo) and "Meetings" (formerly Meet). Understanding the difference between these two modes is essential for effectively using the platform for video conferencing.

Distinguishing Between Legacy Calls and New Meetings

One of the most common points of confusion for former Duo users is finding where the "video conferencing" features start and where the "calling" features end. The unified app maintains both, but they operate on different infrastructures.

Legacy Calling (The Original Duo Experience)

Legacy calling is designed for direct communication with individuals or small groups using a phone number or email address. This mode retains the classic Duo features:

Knock Knock: This allows the recipient to see a live video of the caller before answering, creating a sense of invitation rather than interruption.
End-to-End Encryption (E2EE): These calls are encrypted on the devices themselves, meaning not even Google can access the audio or video data.
Phone Number Integration: You can call someone directly if they are in your contact list, without needing to generate a meeting link.
Group Limit: Legacy group calls are typically limited to 32 participants.

Meet Meetings (The Conferencing Experience)

The "Meetings" side of the app is where true video conferencing lives. This mode is built for scale and collaboration:

Link-Based Access: You create a URL that others can click to join, making it ideal for participants who are not in your personal contact list.
Cloud Encryption: Meetings use cloud-based encryption. This allows for features like live captions, background replacement, and meeting recordings, which require the server to process the media stream.
High Capacity: Even free personal accounts can host up to 100 participants, while Workspace accounts can go much higher.
Collaborative Tools: This includes screen sharing, in-call chat, hand-raising, and digital whiteboarding.

How to Start a Video Conference in the New Interface

Initiating a video conference today requires a slightly different workflow than the old Duo "tap and call" method. Whether you are on Android, iOS, or a desktop browser, the process has been streamlined for speed.

Starting a Conference on Mobile

Open the Meet App: Locate the updated app on your home screen.
Tap "New": You will see a prominent "New" button (often a plus icon) at the bottom right.
Choose "Create a New Meeting": This generates a link immediately. You can copy this link to send via text, email, or Slack.
Join the Meeting: Tap "Join Meeting" to enter the room you just created. From here, you act as the moderator.

Starting a Conference on Desktop

Since the merger, visiting duo.google.com will automatically redirect you to the Google Meet web interface.

Navigate to meet.google.com: Ensure you are signed into your primary Google account.
Select "New Meeting": You have three options: "Create a meeting for later," "Start an instant meeting," or "Schedule in Google Calendar."
Configure Audio/Video: The "green room" allows you to check your lighting and microphone levels before going live. In our testing, the web interface is significantly more robust than the mobile app for managing large galleries of participants.

Advanced Video Conferencing Features You Need to Know

The transition from Duo to Meet brought several high-end features to the general public that were previously reserved for corporate users.

AI-Powered Audio and Video Enhancements

Google has leveraged its leadership in artificial intelligence to improve call quality. The "Lyra" speech codec is a standout feature. It uses machine learning to compress voice data to as low as 3kbps, allowing for clear audio even on extremely unstable 2G or 3G networks. Furthermore, the AI-driven background noise cancellation effectively filters out the hum of air conditioners or the clatter of a keyboard—something the original Duo struggled with during group calls.

Screen Sharing and Real-Time Collaboration

For a true video conference, simply seeing faces isn't enough. The unified Meet app allows you to share your entire screen or a specific window. On mobile, this is particularly useful for walking someone through an app's settings or reviewing a document. On desktop, the integration with Google Docs, Sheets, and Slides allows you to present a file directly from the tab, keeping the meeting controls visible on the side.

Visual Effects and Virtual Backgrounds

While Duo had "fun" filters (like a cat head or a space helmet), Meet provides professional virtual backgrounds. You can blur your surroundings to maintain privacy or upload a custom image. We have observed that the edge detection in Meet’s "Portrait Blur" is currently among the most accurate in the industry, rarely cutting off the user's ears or hair, even with complex backgrounds.

Security Architecture: Understanding Encryption in 2026

When using Google Duo’s legacy calling, your data is protected by a shared secret key that stays on the callers' devices. This is a peer-to-peer connection. However, when you transition to a "Meeting" for video conferencing, the architecture changes.

In a Meet conference, the data is encrypted in transit between your device and Google’s data centers. This "Cloud Encryption" is necessary because Google’s servers need to "see" the data to provide services like:

Live AI Captions: Transcribing speech into text in real-time.
Recording: Saving the meeting to your Google Drive.
Gallery View: Compositing multiple video streams into one layout for your screen.

For organizations with extreme security requirements, Google Meet now offers Client-Side Encryption (CSE). This gives the organization total control over the encryption keys, ensuring that even Google cannot access the content of the video conference.

Managing Group Dynamics and Moderation

A video conference is only as good as its moderation. The Duo-to-Meet evolution introduced a suite of tools for the "Host."

Mute All: In large conferences, background noise from one participant can ruin the experience. The host can now mute everyone simultaneously.
Join Requests: For meetings using a link, the host can "deny" or "admit" people who are not on the original invite list, preventing "Zoom-bombing" style intrusions.
Breakout Rooms: For workshops or large team syncs, hosts can split participants into smaller sub-groups for focused discussion before bringing everyone back to the main room.

Integration with the Google Workspace Ecosystem

The real power of the updated Google Duo/Meet platform lies in its synergy with other tools.

Google Calendar: You no longer need to manually share links. If you schedule a meeting in Calendar, a "Join with Google Meet" button is automatically generated for all invitees.
Gmail: There is a dedicated "Meet" tab in the Gmail app, allowing you to jump into a video conference without switching apps.
Google Home and Nest Hub: You can still say, "Hey Google, call Mom," and it will use the legacy Duo calling infrastructure to ring her smart display. However, if you have a scheduled conference, your Nest Hub will show a "Join Meeting" card 10 minutes before the start time.

Comparative Analysis: Meet vs. Zoom vs. WhatsApp

When deciding if the unified Meet app is the right choice for your video conferencing, it’s helpful to see where it stands against competitors.

Vs. Zoom: Meet is more deeply integrated into the browser. You don't need to download a "launcher" or separate software on a PC. However, Zoom still offers slightly more complex "webinar" features for audiences of 1,000+.
Vs. WhatsApp: WhatsApp is excellent for 1:1 mobile calls but falls short in professional conferencing. It lacks screen sharing from a browser and does not have a "hand-raise" feature or integrated calendar scheduling.
Vs. Microsoft Teams: Teams is a comprehensive "operating system" for work, which can feel bloated for casual users. Google Meet (the Duo successor) feels much "lighter" and faster to launch, making it the preferred choice for ad-hoc video conferencing.

Troubleshooting Common Issues in the Unified App

Even with a world-class infrastructure, users may encounter hurdles.

Missing Effects: If you cannot find filters or backgrounds, your device might be running an older version of Android (below 9.0) or iOS. These AI features require specific hardware acceleration.
Connection Drops: If your video is freezing, Meet allows you to switch to "Audio Only" mode or "Low Bandwidth" mode in the settings menu. This forces the app to prioritize audio over high-definition video.
Audio Echo: This usually happens when a participant has both their phone and computer audio active in the same room. Meet now has "Echo Detection" which will alert the user to mute one of their devices.

What Happened to My Duo History and Contacts?

A major concern during the merger was the loss of data. Rest assured, your message history, "Moments" (photos taken during calls), and blocked contacts have all been migrated to the new Meet interface. To find your old Duo contacts, simply tap the search bar in the Meet app; the algorithm prioritizes the people you contacted most frequently in Duo.

Frequently Asked Questions (FAQ)

Is Google Duo free to use now that it is Meet?

Yes, the core features of Google Meet, including legacy Duo calling and 1:1 video conferences, remain free for anyone with a Google account. Group meetings for free accounts have a 60-minute time limit, which is more generous than several competitors.

Can I still use my phone number to sign in?

Yes. Unlike the original Google Meet, which required a Google Account, the unified app allows you to register with just a phone number to use legacy calling features. However, to host or join a link-based "Meeting," a Google Account is required.

What is the maximum number of people in a Google Duo video conference?

If you use the "Legacy Call" method, the limit is 32 people. If you use the "New Meeting" link method, the limit is 100 for free users and up to 500 or 1,000 for various Google Workspace tiers.

Does the "Knock Knock" feature work in meetings?

No. "Knock Knock" is exclusive to legacy 1:1 calls. Link-based meetings use a "Lobby" or "Waiting Room" system where the host must admit the participant.

Why is my app icon still Duo?

If your icon hasn't changed, you likely have "Auto-Update" turned off in the Play Store or App Store. Manual updating will replace the Duo brand with the Meet brand.

Summary: A New Era for Google Video Communication

The transition of Google Duo into Google Meet represents a significant shift toward a more cohesive digital life. By blending the casual, intimate nature of Duo with the robust, professional capabilities of Meet, Google has delivered a tool that adapts to the user's needs rather than forcing the user to adapt to the tool. Whether you are conducting a high-stakes board meeting or simply saying goodnight to a distant relative, the unified Google Meet app provides a secure, high-quality, and feature-rich environment for video conferencing in the modern age. The retirement of the Duo name might be the end of an era, but the technology it pioneered—from low-bandwidth optimization to end-to-end encryption—lives on in a more powerful form.
