Short answer: imo is a free messaging and video-calling app that focuses on easy international calls, simple chat features, and light-weight performance. It’s used by many people worldwide and offers features like group calls, stickers, and media sharing.
1) Quick background — where imo came from and who uses it
imo started as a small messaging tool that later focused on its own voice and video service instead of connecting to other chat networks. Over time it became a standalone app for video calls and instant messaging. The company says imo has hundreds of millions of users and is available in many countries. (Wikipedia)
Why that matters: imo’s long history explains a few things you’ll notice in the app — it’s simple by design, it supports many languages and low-bandwidth networks, and it keeps adding small features people expect from modern messengers. (Google Play)
2) Main features — what you can do with imo
-
Free HD video calls and voice calls: imo emphasizes video quality and claims to work even on slow networks. This is its core selling point. (Google Play)
-
Text chat and media sharing: Send text, voice messages, photos and short videos. You can create group chats and share files. (Google Play)
-
Group calls: imo supports group video or voice calls (the app pages note multi-person calling features). (Wikipedia)
-
Stickers and simple extras: Hundreds of stickers, status updates, and light social features for casual use. (Google Play)
These features make imo similar to other popular messengers, but its strength is that it tries to keep the app light and usable on weak connections.
3) Security and privacy — is imo safe?
imo states that it uses encryption and has privacy controls. Their FAQ and privacy policy describe protections for messages and how user data is handled. The company highlights end-to-end encryption for private chats and calls in some places of its documentation. (imo.im)
A few practical notes:
-
Read the privacy policy: imo publishes a privacy policy that explains what data they collect and how they use it — good to read if privacy is important to you. (imo.im)
-
Encryption claims: imo says it supports end-to-end encryption for private chats, but like with any app, the exact implementation details and which chat types are E2E should be checked in the app FAQ or updates. (imo.im)
Bottom line: imo promotes privacy features, but if you need the strongest, independently-verified end-to-end encryption for every kind of message (like some secure messengers offer), check the latest official FAQ and independent reviews before relying on it for highly sensitive communication.

4) Performance and real-world use
imo is designed to work across 2G/3G/4G/5G and Wi-Fi. Many users pick it for:
-
Calling friends abroad without paying phone fees. (Google Play)
-
Simple group chats and fast media sharing. (Google Play)
Because the app focuses on being light and compatible with slow networks, its UI and options are intentionally simple. That helps it run on older phones and in places with limited internet.
5) App availability and downloads
You can find imo on Google Play, the Apple App Store, and Windows / PC stores. Play Store and App Store listings describe the app, show recent update dates, and include user reviews and ratings — useful to check before you download. The app has been widely installed over the years, with many millions of downloads reported across platforms. (Google Play)
Tip: Always install from official stores (Google Play / App Store) to avoid modified or malicious APKs from third-party sites.
