This app provides monitoring and information features for the common freifunk user and the technical stuff of a freifunk community.
Code base is taken from a TUM Practical Course project and added here to see if Freifunk Altdorf can use it.

You can not select more than 25 topics
Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
