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.
