Mobile App for Dual Citizens

Hi,

My name is Robert Donnan. I am currently a Level 6 student completing a BSc (Hons) in cloud computing and as part of the course I need to create and develop a project. One of my ideas was to create a mobile app for dual citizens of any country to gather information more efficiently to help make it easier for them to manage their citizenships.

Some of the features would include providing real time travel information on a destination based on which citizenships the person currently holds, allowing users to store documents and passport details(following legislations of course, this idea will be heavily considered and thought out before implementation) , sending reminders of when a passport is going to expire, give recommendations of best second or third citizenships based on what the user currently has, etc. I know a lot of this is already available online but my plan is to make one simplistic app for people to use so they can get real-time updates in one place. I was wondering what you as an expat or dual citizen thought of this idea. Would it be useful? Are there any specific features you would like to see implemented? Has it already been done before? I didn't see any app like it but I could be missing something. I would appreciate it if you would be able to send some feedback. As I am in the very early stages I don't have a lot of specific information as of yet and just want a rough idea on your thoughts on such an app. Thank you for your time, stay safe.

Many Thanks
Robert Donnan
