Thanks for this app which works great. The location-based (cell-id) rule is nice and adds a very useful feature for me. I am sure you know that but in practice, the only drawback is that even sitting at the same position (at work) everyday it took some days before I ended up with stability. After having collected the location, I ended up during the day with surprising non-silent profile while it should have been silent. I realized that actually 3 cell id should be entered to cover the seat at my desk! So thanks again for the wonderful app. But maybe you should make even clearer that a position may be covered with more cell id than only 1.
