That is great to hear. Your app resolves what I was going to leave as feedback. 1) Not everyone is in a city. I'm in an area where a 1km in any direction might not get you anyone. Some areas 2km circle might get a handful of neighbors, but none of them are likely to have the app too. 2) When the app is new, what are they chances that anyone nearby has it? By increasing the range until there is activity, it gives it a way to get off the ground and a way for it to work for people who aren't packed in a city.
