Best expense tracker app in Mexico (2026)

In short

The best expense tracker app in Mexico is the one that handles what's different here: it spreads each "meses sin intereses" purchase into its monthly payments, logs Mercado Pago payments on its own, lets your month start on payday and makes cash, OXXO and SPEI payments quick to log. Kesef covers those points; its limits and six other apps are below, with sources.

Almost any app can log an expense. What decides whether you keep using one in Mexico is local: much of what you pay this month was bought earlier on interest-free months, salaries come twice a month, many payments are cash, OXXO or SPEI transfers, and Mercado Pago is part of daily life. This page lists those needs, how Kesef handles them, and a table with Splitwise, Tricount, Monefy, Wallet, Money Manager and Fintonic.

What an expense app has to handle in Mexico

What	Why it matters here	What to ask of the app
Interest-free months (MSI)	Big purchases are paid over 3, 6, 12 or more months on a credit card.	That it puts each monthly payment in its month, not the total in the month you bought.
Mercado Pago	Many QR payments, purchases and transfers go through it.	That it brings them in on its own, without being able to move your money.
Biweekly pay	Salaries arrive every fifteen days.	That the month starts on payday, not on the 1st.
Cash, OXXO and SPEI	Not everything goes through a card.	That logging a payment takes seconds: by voice or with a photo.
Pesos and dollars	Subscriptions, online shopping or trips in dollars.	That each expense keeps its currency and the total shows in one.
Shared expenses	Roommates, partners, trips.	That it splits expenses and shows who owes whom, free for everyone.

How Kesef handles each point

Interest-free months: you log the purchase once with the total, the card and the term (shortcuts for 3, 6, 9, 12, 18 and 24 months), and Kesef creates every monthly payment with a reminder the day before. Upload the card statement as a PDF (Kesef Pro) and a line like "3 de 12" adds that payment and the ones left.
Mercado Pago: with Kesef Pro you connect your account and QR payments, purchases and transfers come in on their own, categorised. Kesef can't pay or move your money, and an MSI purchase paid through Mercado Pago comes in as one movement for the total.
Biweekly pay: Kesef's period is a month that starts on the day you choose. Each paycheck goes in as income and budgets show what's left per day.
Cash, OXXO and SPEI: dictate it as you pay ("groceries, 850") or snap the receipt. Spin by OXXO, Nu, BBVA and others are on the list of payment methods you add with one tap.
Pesos and dollars: 150+ currencies, each expense in its own and the total in the one you choose, with an international rate fixed when you log it.
Shared expenses: groups with an invite link, free for everyone, with the balance of who owes whom.

Where Kesef falls short

It doesn't connect to banks. The only automatic inputs are Mercado Pago and Apple Pay (on iPhone). Everything else is logged by hand, by voice, from a receipt photo or from the card statement you upload.
It doesn't calculate interest or rates on instalments: if a purchase has them, you log what you'll pay in total.
It reads receipt photos and PDF statements, but doesn't split a receipt by item, and it has no subcategories.
There's no web version and no Android widgets.
The free plan has ads and caps on what isn't daily: 3 budgets, 3 tags, 2 goals, 3 voice entries and 3 image uploads in total. Reading PDF statements is Pro only.

Kesef against six other apps

The same points, for seven apps. Each app's cells come from its official site, its help centre or the Mexican App Store (sources at the bottom). "No data" means its site doesn't say, not that the feature is missing.

How to choose with this list

Try an app for one real month, with your paychecks and your MSI, and check the six points. Whatever forces you to type in what could have logged itself is what makes an app get abandoned. Kesef is free to download and use, so the test only costs that month.
