About this app

Lastro is a personal finance control app that originated from a spreadsheet maintained for fourteen years—and which became an app without losing what made the spreadsheet work.

YOUR DATA NEVER LEAVES YOUR DEVICE

This isn't a promise: it's how the app was made. It doesn't have a server, doesn't require registration, and doesn't create an account for anyone. Everything you record stays in your own phone's database. We can't see your transactions—even if we wanted to, because they never reach us.

THE MONTH ENDS AT ZERO

Gross income, minus withholdings, gives net income. From that, expenses, what you saved, and what's left over are subtracted. A screen shows the five numbers and the bar that divides them—and what's left over can be negative, because sometimes it is.

WHAT THE APP DOES

• Planned and actual transactions, with the month always closed
• Cards with their own invoice, closing and due dates
• Installments with the correct counter (3/12) and the entire schedule
• Recurring expenses that automatically appear each month
• Who in the household spent what
• Assets: investments and possessions, month by month
• The view of the entire year
• Search that spans time: "how much have I spent on pharmacy?"

• Dark mode, and a tap hides all values ​​on the screen
• Biometric unlock

YOUR BACKUP IS YOURS

Since there's no cloud, the app takes seriously the only thing that can make you lose everything: a lost phone. That's why exporting is free, complete, and the app reminds you to do it when there's new information. You can also keep an always updated copy in a folder of your choice.

FREE, WITH ADS

All screens and all rules work for free. The free version displays an ad in the footer, and the ads are NOT personalized — the app does not ask for your advertising identifier and does not track you across apps.

The subscription does only one thing: removes the ad. It does not unlock any features, because there are no blocked features.

Monthly or annual subscription, charged by the store. Payment is automatically renewed and can be canceled at any time in your account settings.
