We have plans to add the various split methods available in the web to the mobile apps in time. However we’re a small dev team so we do not know when we’ll be able to achieve this for all splits on all platforms.
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.Jamie commented
My partner and I have a shared credit card, and we often split purchases and use split wise to track how much we each owe the credit card.
Currently we have made an extra account and named it “credit card” we have to make the credit card the person we owe money to, and then manually split payments removing credit card as someone who splits the purchase.
It would be good to have a way to incorporate shared accounts without all these extra steps.
