No1 CopperPot is a free finance app developed by NUMBER ONE POLICE CREDIT UNION LIMITED for iPhone users. The app allows users to manage their accounts, view statements, calculate loan repayments, apply for a loan, and withdraw funds to their bank or building society. Users can also view all messages and documents from the credit union, update their contact details, and send secure messages to the credit union. Furthermore, the app offers news items and blog posts from the credit union, along with all contact information and FAQs.

The app's setup is quick and easy, requiring users to activate their account and input their first name and member number. For those who have forgotten their member number, the app provides a login help option. If users have already set up an account on the website, they can use the same login details in the app.
