Here are ten of the best free calls apps for Android
1. WhatsApp
WhatsApp is one of the most widely used messaging apps globally, with over two billion users. In addition to sending text messages, it supports both voice and high-quality video calls, even on slower networks. Calls are encrypted end-to-end, meaning no third party—not even WhatsApp—can listen to them. You can also create group voice or video calls with up to 32 participants. The app syncs seamlessly with your phone’s contacts, making it easy to connect with friends and family.
2. Google Duo (Now integrated into Google Meet)
Google Duo, now merged into Google Meet for personal users, is known for its clean interface and high-quality video calls. It works efficiently even on low-bandwidth connections, making it ideal for users with unstable internet. Features include knock-knock (preview of the caller before answering), group calls, and the ability to send video messages. It’s tightly integrated with Android and Google services, offering a smooth user experience.
3. Skype
Skype is a long-standing communication tool trusted by millions. It allows free voice and video calls, instant messaging, and group calls for up to 100 people. Skype also supports screen sharing and call recording, making it useful for both personal and professional use. You can even make international calls to mobile and landline numbers using Skype Credit or subscriptions.
4. Viber
Viber offers free voice and video calls, rich messaging, and group chats. One standout feature is Viber Out, which lets you call non-Viber users or landlines at low rates. It also supports fun elements like stickers, GIFs, and games, enhancing user engagement. Viber provides end-to-end encryption by default and allows for group video calls with up to 40 participants.
5. Facebook Messenger
Facebook Messenger allows voice and HD video calls to other Facebook users, with the added advantage of being widely adopted. Features include group chats, watch-together video sessions, interactive games, and AR filters during video calls. Since it’s linked to your Facebook account, you don’t need a separate phone number to connect with others.
6. LINE
LINE is more than just a messaging app. It offers high-quality voice and video calling, along with features like group chats, stickers, timelines, and games. LINE is especially popular in Asia and has expanded into services like LINE Pay and LINE Today for payments and news. Its group call feature supports up to 200 participants, making it useful for large gatherings or communities.
7. IMO
IMO is a lightweight app designed for users who need fast and free voice or video calls with minimal data usage. It’s user-friendly and works well on 2G, 3G, and slower Wi-Fi connections. The app also supports file sharing, status updates, and encrypted communications. Its minimal interface makes it ideal for older devices or users seeking simplicity.
8. Signal
Signal is a privacy-first messaging app offering secure voice and video calls through strong end-to-end encryption. It’s open-source and doesn’t store any user data, making it a preferred choice among privacy advocates. In addition to secure messaging, it supports encrypted group calls, file sharing, disappearing messages, and even features like incognito keyboard and screen security.
9. Jitsi Meet
Jitsi Meet is an open-source video conferencing platform with no need for an account or app installation—though the Android app enhances functionality. You can initiate secure video calls with up to 75 people, and features include screen sharing, in-meeting chat, call recording (with Dropbox integration), and moderation controls. It’s a solid alternative to Zoom for users who prefer open-source and privacy-respecting solutions.
10. WeChat
WeChat combines messaging, voice and video calling, and a host of other features like social media feeds, payments, mini-programs, and games. It’s particularly dominant in China, but available globally. Voice and video calls are free and reliable, and the app offers a unique feature set like translation tools, location sharing, and more. Keep in mind that WeChat operates under Chinese jurisdiction, which may raise privacy concerns for some users.All these apps provide free voice and video calling over an internet connection and are available to download from the Google Play Store. While most require registration and access to your contacts, each offers unique strengths—whether it’s high security, entertainment features, or professional utilities. Choosing the right app depends on your priorities: privacy, call quality, usability, or integration with other services.
