Any of these sound familiar?
Don't let tedious money calculations ruin a great memory.
Family A fronted the hotel, Family B paid for dinner... who owes who?
Just share the link and everyone enters what they paid. If you set ratios like 'Adult 1.0, Child 0.5, Infant 0', the system calculates the exact balance instantly, whether you're 4 or 40 people.
Why am I paying a full adult share for my toddler's meal?
You can freely adjust the 'burden ratio' for each participant. Baby eats for 0, toddler for 0.3, dad for 1.0—fair amounts are automatically calculated based on your family's reality.
The group chat turns into a stressful accounting thread for a week...
Once everyone logs their payments, one tap shows exactly 'Who sends what to whom'. Share the final receipt link and settle up instantly. No more awkward math text chains.
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.
