Tertiary Travel Expense
Track trip spending by voice
Log a travel expense by typing or speaking one sentence — on-device Apple Intelligence words it cleanly, live ECB rates convert it to your home currency, and a MapKit itinerary planner rounds out the trip.

What Tertiary Travel Expense does
Tertiary Travel Expense is the fastest way to track spending on a trip. Tell the built-in assistant what you spent — by typing or dictating a single sentence like "Ramen lunch 1200 yen at Ichiran Shibuya" — and the expense is logged, worded nicely, and converted to your home currency in one step. Foreign price and home-currency price sit side by side using European Central Bank reference rates across 30+ currencies, with the trip total grouped by day.
Apple Intelligence Foundation Models phrase each entry entirely on-device, so nothing leaves your iPhone. Purchases can carry the shop or place they happened at and open in Apple Maps with one tap, and a MapKit itinerary planner lets you plan stops day by day with real place search and directions. A native SwiftUI app built on SwiftData with iCloud sync — no account, no ads, no tracking.
