Sound familiar? These bill-splitting headaches are real.

Don't let money math ruin a great time together.

Q.

Adults and kids who barely ate paying the same? That doesn't feel right.

A.

Choose to split by individual or by family, then set custom ratios like "Adults = 1.0, Kids = 0.5". The app calculates everyone's fair share automatically.

Q.

I'm always the one covering everything upfront, and it's awkward to ask for money later.

A.

Just share a link — everyone can enter what they paid from their own phone. No one has to hoard receipts, and you never have to chase people for money.

Q.

Gathering receipts and crunching numbers at the end kills the mood.

A.

Open the screen at the end and instantly see who owes whom and how much. All the math is done for you — just collect and you're done.

Q.

Other apps just tell me who to pay, but I never understand exactly how they calculated the amount...

A.

FAMI-KAN features 100% Transparent Math. You can always see exactly why you owe what you owe—including the base unit price and your specific ratio. No more black-box calculations, no more hidden resentment.

Why we built FAMI-KAN

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.

FAMI-KAN isn't just a calculator. It's a partner that handles the math so you can focus on what matters: "That dinner was amazing", "Where should we go next?" — preserving the afterglow of time well spent together.
