|Tox is now usable and has reached alpha (in other words, it is mostly working, but lacking some features, bugs might be apparent).|
uTox is a lightweight (minimal dependencies) Tox client for Windows, Linux and (experimentally) Android. It supports text chat, file transfers, audio and video calling, desktop sharing (both as video and as screenshots). It also supports text-only group chats (with audio/video being worked on).
For more info about Tox and uTox, see the project links below.
If you use an operating system other than windows or linux (OSX or android) or want to try other Tox clients, see this page:
Official Tox website:
Note about adding friends in Tox: in the settings area of uTox you can find your Tox ID, and you give that out to your friends so that they can add you. To solve the inconvenience of sharing long IDs, Tox also supports "DNS names", for example "email@example.com". You can register your own @toxme.se name on toxme.se
Tox is alpha software, bugs are expected.
