Anonymity is going to be hard, even with traditional methods, but I don't think a person's location history can ever be anonymous. Especially when presented with timestamps and spanning days. People generally spend a lot of time, or at least their night, in their home.

Bake it into an existing app that already has the network, I.E. Facebook.
