Cairn - Your Expense Tracker

Cairn is the travel expense tracker built for the way you actually travel — fast enough that you'll still be logging on day five, smart enough to handle every currency without the mental math. Most trackers fall apart on the road: the small coffee never gets logged, your tracker and your card never agree, and you give up by day three. Cairn fixes that. LOG IN SECONDS - A built-in numpad gets an expense in with two taps — no forms. - Cairn suggests the category from where you are (a café becomes Coffee, a gas station becomes Fuel). Location stays on your device. - Capture from your iPhone, Apple Watch, or a Home Screen widget. EVERY CURRENCY, CONVERTED - Spend in any currency; Cairn converts to your home currency automatically using live exchange rates. - Rates are cached, so it works offline — log now, sync later. - Free plan covers 30 currencies; Cairn Premium unlocks them all. SEE THE REAL PICTURE - Organize spending into trips with multiple legs for multi-country journeys. - Set monthly budget envelopes by category and track your pace. - Add income and watch your running balance. - Set savings goals and let unspent budget feed them automatically. ON YOUR WRIST - A full Apple Watch app for logging on the move, plus complications for an at-a-glance balance. YOURS, EVERYWHERE, PRIVATE - Syncs across iPhone, iPad, and Apple Watch through your private iCloud — no Cairn account, no servers in the middle. - Your location is used only on-device to suggest categories. It is never logged or sent anywhere. - Export any trip or your whole history to CSV or JSON anytime. Cairn Premium is available as a monthly or annual subscription, or a one-time lifetime purchase, with a free trial. Track your first trips free.
