Why Okaro?

Standard bookkeeping apps assume one currency. But your life crosses borders. Okaro tackles the gap between the foreign-currency price you swiped and the local-currency amount your card actually billed — built for proxy buyers and serial travelers.

Dual-currency precision

Two columns by design: the foreign-currency total at swipe time and the local-currency amount your card billed. Buy ¥10,000 in Tokyo, get charged NT$2,150 — both are saved.

Credit-card-first UX

Built around cashless life. Manage multiple cards in one place; know exactly which card spent what foreign amount.

AI receipt OCR

Snap a Japanese or English receipt — the AI parses merchant, date, amount, and currency in one shot.

Focused on spending insight, not budgeting handcuffs

Clear pie charts + trends. View by country, currency, or category.

Best for

·Frequent overseas travelers — quick logging on the move, offline-friendly.
·Cross-border online shoppers — multi-currency, multi-card.
·Card optimizers — running rewards strategies while tracking real spend.

Case study

The problem

Standard bookkeeping apps assume one currency. But proxy buyers deal with two numbers per transaction: the foreign-currency price at point-of-sale and the local-currency amount the credit card actually charged. I spent a while inside the proxy-buying community, and the real pain wasn't math — it was the cell-soup of yen, NTD card charges, and prorated shipping crammed into a single Excel column. One typo nuked the margin on the entire batch.

What I built

A dual-currency precision system. Two columns by design: the foreign-currency total at swipe time and the local-currency total the card billed. Snap a Japanese receipt — the AI parses merchant, date, amount, and currency in one shot. The architecture is credit-card-first: every transaction starts from a card, because the proxy-buying scene runs on card rewards.

Technical decisions

SwiftUI 而非 UIKit：Solo dev, declarative UI lets me iterate fast. Drop down to UIKit only where I need surgical control.
App Store over pure web:The audience lives in iPhone + credit-card apps. Native unlocks fast receipt capture, currency widgets, and FX-rate push.
Freemium NT$99/月、NT$999/年：NT$99/mo is the sweet spot I landed on after surveying Taiwan subscription apps; NT$999/yr is "10 months, get 2 free" — an anchor users already understand without being taught.

What I learned

What I learned: the narrower the niche, the easier it is to keep users. I'll never beat a generic bookkeeping app — but in proxy-buying I can be the best.
