Hey Product Hunt! I’m Ed, the solo developer behind Gastos.
My wife and I work abroad and love to travel. We often fly to our home country as well. We wanted to track our spending, especially during trips, for a few simple reasons: we want to know where our money is going, we don’t want to be surprised when the credit card bill arrives after a trip, and we believe you can’t improve what you don’t track.
The main rub: When we travel, we spend in a different currency, and it’s a pain to reconcile that with our everyday expenses at home. Same thing when we visit our country. This friction kept us from tracking — which meant we’d be miserable every time a credit card bill showed up.
I looked at a lot of expense tracker apps, but none of them combined everything we wanted: multi-currency travel support, dead-simple logging (like snapping a receipt or typing “5 lunches”), no account required, and no subscriptions. So like any other software engineer, I built one.
This is Gastos — an AI-powered spending tracker with a travel mode that lets you log expenses in foreign currency while showing totals and insights in your home currency.
– Travel mode handles multi-currency automatically – spend in local currency, see everything back in your home currency
– Three ways to log in: type “coffee 4.50”, take a receipt, or record a voice note.
– Works completely offline – no servers, no accounts. Install and start logging.
– Completely free and ad-free
I’d love to hear feedback, especially on the travel mode flow and whether receipt scanning works well for you. Hope this helps someone else dealing with the same multi-currency headache!
