📱 User Guide – Gastos Offline

Expense & income tracking • Offline • 100% Private

Home / Dashboard

The Home screen shows a summary of your financial activity for the current period:

  • Total balance (income minus expenses)
  • Totals for income and expenses
  • Recent transactions

It’s your control center to quickly see how your finances are doing.

The totals show how much you’ve earned (income) and spent (expenses) in the current period.

The period is calculated automatically based on the cycle start day you set in Settings.

For example: if your cycle starts on day 1, you’ll see data for the current month. If it starts on day 15, you’ll see data from the 15th of last month to the 14th of this month.

The background color reflects your financial situation:

  • Green: Your income is higher than your expenses (positive balance)
  • Red/Orange: Your expenses are higher than your income (negative balance)

It’s a quick visual way to know if you’re doing well this period.

Transactions

Tap the floating (+) button on the main screen.

  1. Select whether it’s an expense or income
  2. Enter the amount
  3. Add a description (optional)
  4. Select date, category, and tags
  5. Tap ‘Save’

To edit: Tap the transaction you want to modify. The edit form will open and you can change all details.

To delete: Press and hold the transaction or use the delete button on the edit screen. Confirm deletion.

Yes. When creating or editing a transaction, you can add an image (like a receipt or invoice) using the camera or selecting from your gallery.

Images are stored locally on your device.

On the Transactions screen you can:

  • Search by text in the description
  • Filter by type (expenses/income)
  • Filter by category and subcategory
  • Filter by tags
  • Filter by amount range
  • Sort by date or amount

Use ‘Clear filters’ to see all transactions again.

✅ All these features are free.
Scheduled Payments

They are rules to automatically create recurring transactions.

Great for:

  • Fixed expenses: rent, subscriptions, utilities
  • Regular income: salary, pension

You set the amount, frequency, and day of the month, and the app generates the transactions for you.

Each rule includes:

  • Amount and type (expense/income)
  • Day of the month it is generated
  • Category and optional tag
  • Active/inactive status

When the configured day arrives, the app automatically creates the corresponding transaction.

The app checks for pending scheduled payments every time you open it.

If a payment date passed while the app was closed, the transaction will be created when you open the app.

No worries about missing payments even if you don’t use the app for a few days.

Yes. Each scheduled payment has an active/inactive toggle.

When inactive, no automatic transactions will be generated until you reactivate it.

Useful if you temporarily don’t have that expense or income.

Categories

Go to Menu > Categories. You’ll see expense and income categories in separate tabs.

Tap ‘+’ to create a new one. You can choose:

  • Name
  • Icon (emoji)
  • Color

To edit, tap an existing category.

They are predefined categories that come with the app, like ‘Other’ or ‘Uncategorized’. They’re marked with a ‘System’ label.

You can’t delete or edit them because the app uses them as default categories.

There are two possible reasons:

  1. It’s a system category (cannot be deleted)
  2. It has associated transactions

If it has transactions, you must move them to another category or delete them first. This protects your data from accidental deletion.

They are categories inside a main category.

For example, ‘Food’ can have subcategories like:

  • Groceries
  • Restaurants
  • Delivery

They let you organize expenses in more detail without having too many main categories.

Tags

Tags are a flexible way to mark and group transactions that share something in common, regardless of category.

Examples of useful tags:

  • Vacation
  • Project X
  • Urgent
  • Reimbursable

You can filter transactions by tag to see related spending.

Go to Menu > Tags. Tap ‘+’ to create a new tag with:

  • Name
  • Icon (emoji)
  • Color

To edit or delete, tap an existing tag.

You can assign multiple tags to each transaction.

Notifications (Limits & Goals)

You can create alerts to receive notifications when:

  • You get close to a spending limit (e.g., spending more than $500 on restaurants)
  • You reach a percentage of a goal
  • You hit a certain amount before your target

Alerts help you stay on track without checking the app constantly.

Go to Menu > Notifications > Limits tab. Tap ‘+’ to create a new limit.

Configure:

  • Type: expenses or income
  • Category (or all)
  • Limit amount
  • When to notify (50%, 80%, 100%, etc.)

The numbers in parentheses show how many alerts you have set up in each section:

  • Limits (3): You have 3 active limit alerts
  • Goals (2): You have 2 active goal alerts

This helps you quickly see how many alerts you have without opening each section.

Backups & Privacy

No. The app works completely offline (no internet connection).

All your data is stored locally on your device. You don’t need to create an account—just a local nickname to personalize your experience.

🔒 Your data is 100% private.

Go to Settings > Backups & Export. Tap ‘Create backup now’ to generate a backup file.

Save this file somewhere safe:

  • Google Drive
  • iCloud
  • Another device
💡 We recommend making backups regularly.

The backup includes all your data:

  • Transactions (expenses & income)
  • Categories & subcategories
  • Tags
  • Goals & alerts
  • Scheduled payments
  • Settings

Attached images are saved separately on your device.

In the Backups section, tap ‘Restore backup’ and select the file.

⚠️ Warning: Restoring overwrites all your current data. The app will restart automatically afterward.

Go to Backups > Export transactions.

You can choose the format:

  • CSV: To open in Excel or Google Sheets
  • JSON: To import into other apps

The file will be saved on your device and you can share it wherever you want.

Before switching:

  1. Create a backup
  2. Save it to the cloud or transfer it to your new device
  3. On the new phone, install the app and restore the backup
✅ You’ll recover all your data exactly as it was.
Premium & Ads

Premium has a single benefit: removing ads from the app.

All app features are completely free. Premium does NOT unlock extra functionality; it only lets you use the app without ads.

ALL features are free:

  • ✅ Unlimited expense & income entries
  • ✅ Create categories, subcategories & tags
  • ✅ Scheduled/recurring payments
  • ✅ Goals & limit alerts
  • ✅ Statistics & historical periods
  • ✅ Manual & automatic backups
  • ✅ Export & import data
  • ✅ Attach images
🎉 No limits or locked features.

Premium is an annual subscription that renews automatically.

You can subscribe from Settings > Upgrade to Premium.

To cancel, go to your store’s subscription settings (App Store or Google Play).

You use the app with all its features, but you’ll see occasional ads.

Ads don’t block any functionality—they’re small banners shown on some screens.

Settings

Go to Settings and select your preferred currency. This affects how amounts are displayed throughout the app.

Note: Changing the currency does not convert existing values; it only changes the display symbol.

In Settings you’ll find:

  • Language: Choose from available languages
  • Theme: Light, Dark, or System (follows your device setting)

It’s a section with irreversible actions that permanently delete data:

  • Delete transactions from the current period
  • Delete ALL transactions
  • Delete all historical periods
⚠️ Each action requires confirmation by typing a keyword to prevent accidental deletion.

It’s the day of the month when your tracking period begins. By default it’s day 1.

If your pay cycle is different (e.g., you get paid on the 15th), you can adjust it so your “current period” totals match your real finances.
