imo is available as a free download. After downloading the app and verifying your phone number, you are ready to go. The mobile app supports instant messaging, HD-quality voice chatting, and video calls. It has its own sticker library and group video calls are supported.
The Android version of the app has been downloaded more than 500 million times, which actually sets it at the very top of the market, just below the powerhouses. imo does enjoy a clean design and chatting one-to-one can feel much cleaner without being interrupted by many things Messenger offers, for example.
You are still able to send photos, videos and files, or you can draw something on your screen. Video and voice calls are high-quality and that is something which can set imo out from the competition. Besides that, it is just another instant messaging app which offers fewer features than other apps.
Also, imo has stated that its chats and calls are encrypted but it's impossible to find out anything about the encryption used. This has sparked some outrage regarding some security concerns recently. Otherwise, it is a nice app but it's not something you need on your phone and it's not worth talking all your friends and family into downloading it on their phone.
