The USO app, developed by United Service Organizations Inc., is a free lifestyle app available on Android. It offers service members and their families the ability to quickly find USO locations, learn about amenities and services available, discover USO programs and events offered at nearby locations, and explore USO locations and programs around the world.

One of the most convenient features of the app is the ability to contact USO locations by email, phone, or Facebook. For service members and their dependents, the app enables them to skip the line at USO locations and check-in from the app. Additionally, users can rate their experience at USO locations they've visited.

Overall, the USO app is a great tool for those looking to connect with USO locations and access their services. Although it is the first version of the app, users can provide feedback through the in-app feedback feature to help improve the experience.
