imo for Windows 10 is a messaging app that combines text messages, voice calls and video chat. While imo might superficially seem similar to other messaging apps such as WhatsApp, Hangouts or Skype, it differs in that it offers not only text chat but high-quality video and voice chat over your internet connection.
A simple but versatile communications app
Logging into imo for Windows 10, you'll be confronted by a simple, minimalist interface. You have a window for chat and a window for your contacts, with little else. This simplicity is one of imo's best features, but some users may find that it limits customisation options. Call quality is good, even on group video chats, although as with all video or voice chat applications this depends as much on the internet connection as on the app. Contacts will transfer automatically from your device's contact list, although of course these contacts will need to be imo users for you to be able to chat with them. Like most chat apps, this one offers minor extra touches like the ability to send images and stickers.
Simple but limited in some ways
If you need to chat regularly with a small group, imo for Windows 10 is an easy way to do it, but its lack of some options means it's unlikely to replace other chat tools as your go-to.
