Why FAMI-KAN is Best
When one partner earns noticeably more, a 70/30 split is one way to keep shared spending fair: each of you pays the same portion of what you earn, so the gap in pay doesn't turn into a gap in what's left at the end of the month. If one of you earns $7,000 and the other $3,000, that's exactly 70/30. If the gap is smaller, 60/40 or 55/45 may fit better. The friction usually isn't the ratio itself but the tally. One person tends to pay at the grocery store, the other picks up dinner, and after a few weeks nobody knows where things stand. Say Partner A spent $600 on groceries and Partner B $300 on dates this month. The total is $900, so A's 70% share is $630 and B's 30% is $270. A sends B $30. In FAMI-KAN, set your ratio to 0.7 and 0.3 once, and each of you logs payments from your own phone. For anything you want to split 50/50, use "Change shares for this payment only". At month end, one transfer squares things up.

The worst part of any trip comes at the very end — when everyone's tired and someone has to sort out the money. Lining up receipts, punching numbers into a calculator, trying to remember who paid what... it brings a cold, transactional feeling to what should be warm memories.
Existing apps are useful, but often too complex or require everyone to install the same app. For family gatherings spanning multiple generations, we needed something simpler — and warmer.

Frequently Asked Questions
Divide each income by your combined income. If one of you takes home $4,900 a month and the other $2,100, the total is $7,000, so the shares are 70% and 30%. Enter them as 0.7 and 0.3 and every payment is split that way.
That's up to you. One option is to keep groceries at 70/30 and split dates evenly. On an $80 dinner, 70/30 is $56 and $24, while 50/50 is $40 each; switch any single payment with "Change shares for this payment only".
Changing the ratio recalculates every payment already in the event. To keep past months as they were, settle the current event, then duplicate it from the history on the home page and set the new ratio there.
Enter the receipt as two payments: the shared part at your usual ratio, and your personal items with only you under "Target Members". That way only the shared part is split.
Treat it as the shared wallet. Record each deposit with "Give to Organizer" and bills paid from it with "Organizer pays". The settlement shows whether one of you has put in more than your 70 or 30 share.
Yes. Give each payment a category, such as groceries or dates, and sort the History tab by category or by date.
Enter each payment under whoever paid it. Even when the big bills are split between you like that, FAMI-KAN adds everything up at your ratio and shows a single difference to settle. For souvenirs or anything just for yourself, set "Target Members" to only you so it stays out of the split.
