Using Threema Gateway, you can send, receive, and process Threema messages by means of your own software. Whappodo has used this technique to create a useful service for retrieving regional Corona stats.
Simply send a location (as location, not as text message) to the Threema ID *COVIDEN, and, in return, you’ll receive the current Corona stats for that region: Give it a try!
Currently, locations in Austria, Germany, and Switzerland are supported. For this service, the privacy policy (German) of the provider Whappodo applies.
The Corona Radar showcases how Threema Gateway can be used in clever ways.
