Cash and IC cards are invisible to feeds
Cash use in Japan remains high by developed-market standards, and Suica or PASMO top-ups obscure what the money was actually spent on even when a card was involved. Any app relying on bank import is structurally unable to tell you that ¥600 went on lunch. Cash Compass records what you tell it, so cash, IC card and credit spending all land in the same categories and totals.
