Skype is a communication app that combines instant messaging, voice and video calling, and SMS handling into one tool, making it easy to stay connected with friends, family and colleagues. Use it for free one-to-one chats or group conversations, join HD video calls for up to 24 participants, or send SMS messages to mobile phones around the world. The app also supports file sharing and screen sharing, and SMS Connect lets you read and reply to your phone's SMS messages from your computer as the feature is rolled out gradually.

Key Features

Skype offers HD video calls for one to 24 participants in high definition. It includes instant chat with group conversations, @ mentions and quick messaging. SMS Connect lets you read and reply to your phone's SMS messages from your computer while the feature is being released gradually. You can share photos and videos and save shared media to your camera roll, use screen sharing to collaborate or present in real time, and place voice calls to other users or call mobile phones and landlines at low rates.

Advantages

Using Skype combines messaging, voice and video in a single app to simplify communication across formats. HD group video for up to 24 people helps remote gatherings feel more personal and engaging. SMS Connect can improve response times and workflows by letting you manage phone SMS from your computer, and easy media and screen sharing tools support planning, presenting and preserving memories.

Disadvantages

Some SMS features such as SMS Connect are being rolled out gradually and may not be available in all locations yet. Calls to mobile phones and landlines require credit or a paid plan and are not free. Group video calls are limited to a maximum of 24 participants, which may not suit very large meetings.
