The best expense tracker app in Argentina is the one that handles what's different here: it logs Mercado Pago payments on its own, spreads instalments by month, handles pesos and dollars in the same month, lets the month start on the day you get paid, splits expenses with others and doesn't make you pay to log. Kesef ticks all six; its limits are listed below.
Any expense app can log a coffee. What separates a useful app in Argentina from one abandoned within a week are the things that happen here every day and don't in other markets: half of daily payments go through Mercado Pago, half of big purchases are in instalments, people earn in one currency and save in another, and most people's month doesn't start on the 1st. This page is a checklist of that, without naming other apps: you can measure any of them against the list.
What an expense app has to handle in Argentina
| What | Why it matters here | What to ask of the app |
|---|---|---|
| Mercado Pago | A good share of daily payments go through it: QR, transfers, purchases. | That it brings them in on its own, read-only, without asking for your bank password. |
| Instalments | Big purchases are made in 3, 6, 12 or 18 instalments on a credit card. | That it spreads each instalment into the month it falls, not the total into the month of purchase. |
| Two currencies | People earn in pesos and save in dollars, or the reverse; they travel. | That it logs each expense in its currency and shows the month in one. |
| Your own month | Payday is the 5th, the 10th or the 23rd, and fortnightly pay exists. | That the month starts on the day you get paid, not on the 1st. |
| Shared expenses | Couples, shared flats, trips: money gets mixed. | That it splits expenses and says who owes whom, free for everyone. |
| Price and data | Logging shouldn't cost anything; the data is yours. | A free plan with no cap on logging, and export. |
How Kesef handles it, point by point
- Mercado Pago: link your account and payments come in on their own, with their category, read-only. It's part of Kesef Pro. Mercado Pago instalment purchases come in as a single transaction for the total, not spread out.
- Instalments: log the purchase once with the total and the number of instalments, and each month shows its own, with a reminder the day before each due date. Free.
- Two currencies: 150+ currencies, each expense in its own, converted when logged to see the month in one. Free. The rate is fixed at logging time; it can't be chosen or adjusted later.
- Your own month: pick the day your period starts, and budgets tell you whether you're on track or going fast and how much you can spend per day until it ends. Free.
- Shared expenses: groups with an invite link, split per expense (equally, by percentage, by shares), a common fund and a daily reminder to whoever owes. Free for every participant.
- Price and data: logging, groups, recurring expenses and sync with no cap on the free plan; JSON and CSV export of the last 30 days free, and of the full history and to Excel with Pro.
Where Kesef has limits
For the list to be useful it also has to say what's missing, because that's what you'll look for in another app:
- It doesn't connect to banks. The only automatic inputs are Mercado Pago and Apple Pay (on iPhone, through a Shortcuts automation). In-store card purchases without Apple Pay are logged by hand or by voice.
- It doesn't adjust for inflation or let you choose the exchange rate: the rate is taken at logging time and stays fixed.
- It doesn't store receipt photos or attachments, and it has no subcategories.
- It has no overall budget and no group budget: budgets are per category and personal.
- No web version and no widgets on Android.
- The free plan has ads and caps on what isn't daily: 3 budgets, 3 tags, 2 goals, 3 voice entries, 3 Chat questions per month.
What about a spreadsheet?
The spreadsheet is any app's biggest competitor, and it wins on flexibility and on already being set up. It loses on what decides whether logging lasts: entering from your phone in the moment, expenses that come in on their own, instalments spread without a formula, and groups. If you've kept your spreadsheet for two years, you probably don't need an app; if you've abandoned it three times, the problem was the logging, and that's what an app changes.

How to use this list
Try the app you're looking at for a real month, with your transactions, and tick the six points. Whatever it doesn't handle in the first month it won't handle later, and whatever makes you log by hand every day is what will make it last a week. Kesef is free to download and use, so the trial costs a month of your time and nothing else.
Frequently asked questions
What's the best expense tracker app in Argentina?
The one that handles what's different here: Mercado Pago logged on its own, instalments spread by month, pesos and dollars in the same month, a month that starts on payday, shared expenses and a free plan with no cap on logging. Kesef ticks those six; this page also lists its limits.
Are there expense apps that connect to banks in Argentina?
Kesef doesn't connect to banks: its automatic inputs are Mercado Pago (by linking the account, read-only) and Apple Pay (on iPhone). This page doesn't compare other apps by name; measure the one you're looking at against the list.
Why doesn't this comparison name other apps?
Because a ranking goes stale in months, and because the useful question isn't which is "the best" but what an app has to handle in Argentina. Named comparisons exist only for the apps people search for by name: Splitwise and Tricount.
Is Kesef free?
Yes: downloading and using it is free, with no cap on logging, groups, recurring expenses and sync, with ads. Kesef Pro is optional (USD 5 per month, 35 per year with a 14-day trial, or 100 for life) and adds automatic Mercado Pago and Apple Pay, unlimited voice and Chat, no ads and no caps.
