Partake is the easiest way for couples to share expenses. It syncs with your bank or credit card, gives you all of your transactions in a live feed, and you just tap the ones that are shared expenses – then you split them. Partake keeps up with those expenses you share – easy! Think divorced parents sharing expenses for their kids. Splits are 50/50 presently, but they’re working on changing that. Suggestions from the NYTM crowd: market it to roommates and small businesses sharing expenses.
