Don't let tedious money calculations ruin a great memory.

Q.

Is it rude to ask to split it differently because I only have 1 kid?

Set standard ratios (Adult 1.0, Kid 0.5). FAMI-KAN builds the fair split objectively, removing social friction.

Asking friends for $8 is uncomfortable.

Why we built FAMI-KAN

At the end of a fun trip, the worst part is figuring out who owes what. Pulling out receipts, calculating, and remembering who paid for what brings a cold, administrative feel to great memories.

Existing split-bill apps are useful, but often too complex or force everyone to download an app. We wanted something simpler and more welcoming.

FAMI-KAN is not just a calculator. By letting the system handle the math, you can focus on the fun conversations and memories. It's a partner that preserves the joyful afterglow of your events.
