Feedback 1: Great public service idea! Would be great to see more on the mechanisms to detect spam or reports that are not useful. It looks like the photo upload feature was not working for me either. Consider a function for other users to "upvote" or otherwise backup previous user reports, rather than having to upload their own new photo. Some of the images for reports were pretty slow to load as well - consider rendering the photos in smaller size for thumbnail uses. Note that when viewing on small screens, the About page does not resize the YouTube video as well. Finally, consider how a the user would actually use this information - how does the community benefit? Will they change where and how they travel? If so, maybe consider providing a feature that helps them with this.
Feedback 2: I love the idea. The app was fast, simple and seamless. It wasn't clear what the "Surface", "Sign" and "other" buttons were for. In summary, great effort!
