There is a new App available for beta testing for Windows, MacOS, and Android (phones and tablets). This app allows observers to: 
- Show public messages sent by the observatory
- Show private observer messages sent to and from the observatory
- Send private observer messages to the observatory and receive replies typically within a few seconds
- All usual #hashtag commands can be used (see Basic and Advanced commands).
- Plain text commands can also be used for common commands.
- With the Android version, you can talk to the observatory and it talks back!
- Access observatory web pages (queues, etc.) using the built-in web browser.
- Browse web links in message replies and in public and private messages using the built in web browser.
