Here is what Duo Split looks like in action.


The separation of expenses in an equitable way is essential in a couple. Just thinking about the number of daily expenses, it is normal that money is one of the main causes of conflict in couples. It is important to develop a realistic budget. Making a budget is one thing, sticking to it is another. Mismanaged joint accounts, hidden expenses between partners or even sums of money that disappear inexplicably are all sad scenarios that unfortunately happen too often. The causes are often a lack of financial education, a lack of communication or poor budget monitoring. Having the right tools to respect to your budget is essential.

There are a variety of mobile applications for tracking a budget, a wide variety for separating expenses, but rare are the ones that combines these two aspects at the same time, while addressing the specific challenges of couples. Managing expenses remains an issue within couples. A clear separation between personal and couple budgets must be defined.

It's in 2018 that the Duo Split mobile application is born to manage budgets and keep track of the couple expenses of its creator and the ones of its couple. At first, the idea was to use an existing mobile application to avoid reinventing the wheel. Surprisingly, none of them had the capacity to manage evolving budgets and keep track of couple expenses in a practical way. After getting interest from people who struggled to manage couple expenses, the application has been adapted to allow several couples to benefit from this tool as well. Specifically designed for couples by a seasoned software engineer, Duo Split encourages a systematic separation of couple and personal expenses into separate budgets to avoid misunderstandings. It's never been easier to know at a glance how much you owe your partner and instantly know if you respect your budget. Used by its creator since its creation, Duo Split gets refined year after year.

It's now up to you to take control of your couple spendings with Duo Split!
