I need to manage my storage unit remotely; what's a good Android app for accessing gate codes and paying bills on the go?

From an academic perspective, the Public Storage app presents an interesting implementation of access control. The Bluetooth gate access, while potentially vulnerable to exploits, offers a convenient solution for users. The ability to manage payments, especially setting up autopay, is pedagogically sound, reducing late fees and simplifying the rental process. It's cross-platform compatibility, being on Android, is also a significant advantage. This app could be quite helpful for graduate students managing their belongings while doing field research or professors who need to store materials between semesters. The app's ability to remotely manage storage units presents a novel approach to an old problem, and the algorithm for gate access, assuming it's secure, is surprisingly elegant. It would be interesting to see a formal security analysis of the Bluetooth access mechanism.
