Distance of Chipolo displays both graphically and numerically on the app, which does not open up for me, to which unit of measure is. There are definitely no meters. Ultimately, however, not matter, because is important not so much the exact distance (which also varies in other, although neither mobile nor Chipolo move), but rather whether one approaches or removed.
Furthermore, can be adjusted if the app should contact if you go out of range, or even approaches again. The horn is a fairly soft sound on the Chipolo can play. Lauter would be better, but this is also audible in a quiet environment. Shaking the Chipolo leaves a note on the phone to play, the reverse option so if you time looking for his cell phone.
The maximum distance I can not fathom, but is also certainly depends on whether visual contact. In my experience, there are 15-50 meters.
In sum, I am very happy because I was looking for a version that runs on Android. Due to the poor ratings of stick place I came across Chipolo. Pity the Chipolos on Amazon can be ordered only separately and not as on the homepage in different quantities and thus then also cheaper.
