- Splitwise has monthly expense reports that can be used for that purpose, even though it may not be the best to portray this kind of relationship, since it will portray expenses as "debt"Love Splitwise. Been using it to manage expenses with friends for eons now. It is extremely nifty, I love the reports and alerts functions. Works well with friends, and I've had a few couples use it too, to manage their expenses.
A friend introduced me to split wise while we were vacationing and it's an amazing app. No more mental notes on who paid for what.
Works great in office when we are ordering food or go out for tea :)
- Check this app for couples, got featured here couple months back. No pun intended.
Zeta is helping my boyfriend and I organize our finances, allowing us to split expenses and keep track of what we owe each other. It is even helping us prepare to to buy a house together.
Really wanted to give this app a try ><.
- I use Next. This has as far as I know no partner accounts, but a really solid iCloud sync. The interface is really awesome and made for easy expense tracking on the go. The statistics are detailed enough and for cross reference I use the excel export to feed that into my bank account managing software.
