Hi there,
Its a simple android app, ok as you want i will create sqlite DB for registered contacts.
or i can store them in cloud databse(firebase db)
user will be able to create, edit, delete data, search for special items and
any other feature you want?
We are a professional team of Developers, in Android, IOS, Web, etc. We can design your app, as well as you wish.
So I support the app at least for six months, which means ill fix the bugs for free.
I'll be glad to work with you and your project.
Thank you for the time you spent to read me.
