Splitwise has some basic support for this now, depending on what you’re looking for. We now support multiple email addresses for a single account, so you can more easily share one account with multiple people.
However, we won’t automatically adjust how much you should owe as a “couple”. For example, if “Bob” adds an expense with “Sue and John’s Couple Account”, then the bill will be split 50/50 between those two Splitwise accounts. I can definitely see how it would be useful to automatically make Sue and John pay for 2 shares, but we’re unlikely to add that feature in the near future. For now, you can still work around this by manually using the “Split by shares” option when adding a bill, and assigning 2 shares to the relevant account.Ryan strom commented
A recent trip exposed what I suspect is a regular use case. My wife and I went on a trip with other couples and wanted to consolidate our debt together so that we were only paying between couples. We still wanted to be in as individuals though because sometimes only some people from each couple would be involved in specific activities (attracting shared costs unevenly). So when we went to settle up we wanted to be able to just consolidate the debt inside the couple so we would only have to settle up between couples. Suspect it could work within the debt simplification module....Ryan strom supported this idea ·
