I was at home, few days after a trip on Europe.
I saw a really awesome picture on Instagram, and I said: "Wow, I want to be there!". After researching a bit, that photo was taken on Rome. 3 months ago I was in Rome and I never saw that place, considering that I walked in that street ~2 times.
There I realized that there was no app to "discover the best photo spots nearby". So, it started.
