As mobile technology sustains exponential growth and spread to all aspects of our everyday life and smartphone computational power increases, new promises arise for cultural institutions and citizens to use these tools for promoting cultural heritage. This survey proposes to review available smartphone applications (apps) relating to cultural heritage in three different contexts: cities, street art, and museums. Apps were identified by searching two app stores: Apple's App Store and Google Play (Android). A data search was undertaken using keywords and phrases relating to cities, street art, and museums. A total of 101 apps were identified (Google Play only= 7, Apple App Store only = 26, both Google Play and Apple App Store = 61, Apple Web Store and Web App = 6). Apps were categorized into the following categories: museums (39), street art (30), and cities (32). The most popular features are photos (96%) and maps (79%), and the most uncommon the 360 (4% – only in museums apps), games (6%), and video (15%).
