Ask HN: Idea Sunday
Just going to throw this one out there. I live in Lisbon, it's tourist-central (I'm from SF and I've never seen so many tourists). Since I see a ton of lost people every single day there should be a way to digitally leave comments on things and places and a free one-stop shop to find such info (like Wikitravel). This info, although having a central repository, should be pushed out to an app that connects to one's phone (in particular, GPS) so that when you need help with figuring out where you are, what statue you're standing in front of, etc, you can open the app and it tell you (no entering anything...only if you want to get to another location).By entering what you want to do beforehand, the app would know where you are and have a list of places you said you want to go, and tell you how to get to the next closest place, or alert you if one on your list is about to close for the day. Perhaps each city version is done by locals and in case of bad actors, there can be a voting system so the right info goes to the top. Plus, there could be integration with Google Maps so you can see if you're going the right way.
