People using GPS definitely use the visual side as a guide, but to say they are glued to their phones is definitely an exaggeration.

This is true, there are definitely some people who know the streets very well and don't need the know the safest route. However, to say most people who walk home at night fall in this category is also an exaggeration.

But what if the person doesn't want to waste money on an Uber?

I think this app could have a lot of use for college students walking to parties late at night or little kids who are walking home from school.

I think the app will definitely help those walking at night feel safer knowing the locations of nearby crimes.

I also thought about this while building the app. The user has the ability to choose between a plethora of options that maximize their preferences for safety and speed, they are not just being forced to choose one route. Moreover, the routes are all calculated from where the user is located, so different users will get different routes depending on their individual locations in the city. Lastly, the database is getting updated hourly with new data from the past day that could change the recommended routes, so if a criminal catches someone it would most likely be due to random chance rather than because the app is making the user more vulnerable.
