Will I make it to the end of the month?
I kept my finances in a spreadsheet. It worked, but logging every expense was such a chore that I kept putting it off, and the number stopped being true. No app offered what Argentina needs: installments, two currencies living together and a credit card that closes one month and is due the next. The goal was a single one: make logging an expense easy, and let the question answer itself.
- 01Log without frictionAdd an expense by voice or in two taps. If logging is a chore, the app dies.
- 02Built for ArgentinaInstallments, pesos and dollars, and the card with the bank’s real dates, not a calendar month.
- 03One answerThe whole design points to one number on the home screen: how much you have left until the end of the month.
- 04Design by using itI was the first user, every day; every screen was adjusted with real use, mine and my friends’.

Chanchito is a personal finance PWA designed from scratch for Argentina. It tracks expenses and income, installments and subscriptions, investments in pesos and dollars, goals and budgets, and answers the question that matters: will I make it to the end of the month? A voice chat in Rioplatense Spanish on Gemini 2.5 Flash lets you log transactions by talking. It is my own product: I defined it, designed it and built it directing coding agents, and I run it with real users who came in from a post and report what they find.
