Meet HiBi-Kakei

HiBi-Kakei is a household ledger for your phone. Write down what you spend, keep every bill in one place, and get a gentle nudge before anything is due.

One app, three moods.

Sakura

Cherry blossoms over a quiet street. Petals drift down while you note the day's chai.

Neko

A cream page, a blossom branch, and a sleepy cat napping right on today's total.

Yoru

A lantern-lit old town under the stars. Fireflies glow while the cat watches the waves.

What it does

Everything a household ledger needs, and nothing that gets in the way.
