I picture this as an app that's meant more for areas of the world where harassment is much more prominent/aggressive and those that do it are condoned to the point it's considered "acceptable" at a deep-seated, culture-wide level. While harassment is still an issue in the United States, it's nowhere near the point or daily creep factor it is in some areas of the world. While you bring up some good points in the view of someone living in the United States, I don't believe women (and ethical men) in every part of the world would agree. There was just a report on the BBC the other day where they interviewed women in India about the level of harassment they endure and if it has gotten better since last year when that poor medical student was raped and murdered on a bus. They all agreed that dealing with being regularly groped by men was just a part of "daily life," which is just sad. They also said that when they speak out about it, fallacies such as "women should not be out at X time of day" or "an upstanding woman that does not want that kind of 'attention' should not wear X." While there are reports of that happening in the US, no woman I know would claim it's just a part of daily life.
