Feature description

It would be interesting for me as a user if the app would show the number of contacts with other devices. As a user, that would give me a feeling of whether the system "works". To maintain anonymity, only one update per day.

Example:

• Detected contacts: 10 devices
• Contacts >15min: 2 devices

Problem and motivation

As a user, that would give me a feeling of whether the system "works".

Is this something you're interested in working on

No

This is not possible to accomplish, please see my comment on this issue in the iOS repository for more information.

I think that is possible to implement. You can count the number of local stored keys for example. That would give a first impression on how many contacts there are. The time is more complicated i think. If I am wrong with this idea, pls tell me.

Please see my mentioned comment above for the reason you cannot count the total number of keys. The app has only restricted access to the key database and cannot fetch all keys. More precisely, the app only gets information from the framework if a matching key was tested positive.

Thank you all for your feedback and @joerghaf for the initial idea. Since we already have a wishlist item for that, we'll close this ticket here in this repository.
