Travel expense tracker: every currency, handled.

Why travel breaks a normal expense app

Regular expense apps assume one currency and one phone. On the road, both assumptions fall apart. Every receipt is in a different currency, so your totals are meaningless until something converts them. You're switching between cash and cards, grabbing receipts you'll never re-open, and the last thing you want is to download and learn a new app while standing in a night market. Friction is already high when you travel — a tracker only helps if logging a receipt takes seconds.

Snap the receipt — in any currency

The capture is the same gesture you already use to send a message. Point your camera at the receipt — a ¥1,200 ramen counter, a €4 espresso, a ฿350 tuk-tuk — and send it in Telegram. The AI reads the shop, the line items, the total, and the currency right off the receipt. No dropdown to set, no "what currency was this?" prompt. Didn't keep the receipt? Send a voice note — "breakfast in Lisbon, about nine euro" — and it files the same way.

One trip, one home-currency total

Here's the part that makes a trip legible: each foreign receipt is converted at the day's exchange rate and rolled into one running total in your home currency. So instead of a pile of amounts in five currencies, you get a single honest number for the trip. Later you can just ask, in plain words — "how much did I spend in Japan?" — and get an answer built from your real receipts, already converted. (When a rate is a little stale, the report says so, rather than pretending to a precision it doesn't have.)

No app to install while you're abroad

Because it lives in a chat, there's nothing to install and nothing that's tied to your operating system. iPhone in one city, borrowed Android in the next, laptop in the hotel — it's the same Telegram account, the same bot, the same ledger. That matters on a trip, where you don't want to be managing app updates or app-store regions just to log a coffee.

Your trip data stays yours

Every entry is saved as a plain-text Markdown note in the open Obsidian format — so once you're home you can export the whole trip as a folder of files, keep it for your records or a reimbursement claim, or delete it outright. It's never used to train AI. A travel tracker touches a lot of personal detail — where you were, when, and what you bought — so where that data lives matters as much as how easily you captured it.
