I use my credit cards a lot as well as my debit cards and I have some ideas for features. Not all spend works like the calender months, different people have different billing dates for credit cards etc.
Add credit limits - I know how much I’ve spent against my limit and on what card
Add statement dates - not all credit card statements are done by calendar month so adding my billing date will tell me where my spend is upto based on my billing date and not calender month.
Budget tracker- Assign a monthly spend budget which the curve card will draw down against. If all I use is my curve card it will let me know how much I have left in that particular account. Allow multiple accounts.
Pay day - insert a pay day date this allows me to work pay day to pay day.
Card groupings - two groups.
1 - Cash expenditure
2 - Credit expenditure
Allow me to group cards into cash and credit therefore knowing how much actual money I have spent and how much borrowed money I spent.
Give an overview of total monthly expenditure for the calendar month and then I can go into detail by cash or card and then drill down further by card type.
If your looking for a product owner let me know . Been using curve since its launch and I swear by it but it has so much potential. As a digital marketer I also know what this would enable from a marketing and analytics perspective. For the user it becomes a single point of management without ever having to leave the app and for curve you don’t need to become a bank to facilitate it.
