Key Features

💸 Budget Management

Custom Budgets and Time Periods: Set up personalized budgets with flexible time periods, such as monthly, weekly, daily, or any custom time period that suits your financial planning needs. A custom time period is useful if you plan on setting a one-time travel budget!
Added Budgets: Selectively add transactions to specific budgets, allowing you to focus on specific expense categories.
Category Spending Limits per Budget: Set limits for each category within a budget, ensuring responsible spending.
Past Budget History Viewing: Analyze your spending habits over time by accessing past budget history, enabling comparison and tracking of financial progress.
Goals: Create spending and saving goals and put transactions towards different purchases or savings. Track your progress towards achieving your financial goals.

💰 Transaction Management

Support for Different Transaction Types: Categorize transactions effectively based on types such as upcoming, subscription, repeating, debts (borrowed), and credit (lent). Each type behaves in certain ways in the interface. Pay your upcoming transactions when you're ready, or mark your lent out transactions as collected.
Custom Categories: Create personalized categories to organize transactions according to your unique spending habits. Search through multiple icons and select the default option as expenses or income when adding transactions.
Custom Titles: Automatically assign transactions with the same name to specific categories, saving time and ensuring consistency. These titles are stored in memory and popup when you add another transaction with a similar name.
Search and Filters: Easily search and filter transactions based on various criteria such as date, category, amount, or custom tags, enabling quick access to information.
Easy Editing: Long-press and swipe to select multiple budgets, edit accordingly as needed or delete multiple at once.

💱 Financial Flexibility

Multiple Currencies and Accounts: Manage finances across different currencies and accounts with up-to-date conversion rates for accurate calculations and effortless currency conversions. The interface shows the original amount added and the converted amount to the selected account.
Switch Accounts and Currencies with Ease: On the homepage, easily select a different account and currency and everything will be converted automatically in an instant.

🔒 Enhanced Security and Accessibility

Biometric Lock: Secure budget data using biometric authentication, adding an extra layer of privacy.
Google Login: Conveniently log in to the app using your Google account, ensuring a streamlined and hassle-free authentication process.

🎨 User Experience and Design

Material You Design: Enjoy a visually appealing and modern interface, following the principles of Material You design for a delightful user experience.
Custom Accent Color: Personalize the app by selecting a custom accent color that suits your style, or follow that of the system.
Light and Dark Mode: Seamlessly switch between light and dark themes to optimize visibility and reduce eye strain.
Customizable Home Screen: Tailor the home screen layout and widgets to display the financial information that matters most to you, providing a personalized and efficient dashboard.
Detailed Graph Visuals: Gain valuable insights into spending patterns through detailed and interactive graphs, visualizing financial data at a glance.

Detailed Parameters

The following is a list of all and additional (not fully supported) parameters that can be passed in. They are ordered in terms of precedence, the parameters at the top will be parsed before the ones below. Therefore, overlapping fields will be proceeded by the first parameter.

JSON List of Transactions

The input JSON for addTransaction and addTransactionRoute should follow the following format:

{
  "transactions":[
    { ... },
    { ... },
    { ... }
  ]
}

As an example:

{
  "transactions": [
    {
      "amount": "-100",
      "notes": "This is a note",
      "category": "Shopping"
    },
    {
      "amount": "-150",
      "notes": "This is a note 2"
    }
  ]
}

Don't forget to encode the JSON in the URL as JSON uses invalid URI characters. Once encoded, the output link would look something like:

https://cashewapp.web.app/addTransaction?JSON=%7B%22transactions%22%3A%5B%7B%22amount%22%3A%22-100%22%2C%20%22notes%22%3A%22This%20is%20a%20note%22%2C%20%22category%22%3A%22Shopping%22%7D%2C%7B%22amount%22%3A%22-150%22%2C%20%22notes%22%3A%22This%20is%20a%20note%202%22%7D%5D%7D

Troubleshooting

Android

If you get redirected to the website instead of the Cashew app, your device may not be correctly set up to open App Links. Ensure Cashew can open its respective app link. On your Android device head to your device settings, 'Default apps', 'Opening links' and ensure Cashew has permission to open from the domain cashewapp.web.app under 'Supported web addresses'. This may be disabled by default if you did not install a Google Play signed copy of Cashew (i.e. downloaded from GitHub). This is because Cashew now uses App Links which need to be verified as per Android 12+ requirements with an app's signature public key. Alternatively, you can use a redirect application such as LinkSheet which can manage which apps open when certain links are activated.

Testing

Using ADB for Android

You can use ADB to test app links. For example

adb shell am start -a android.intent.action.VIEW -d "https://cashewapp.web.app/addTransaction?amount=-70\&title=Grocery%20Shopping\&date=2024-03-02\&category=Food\&subcategory=Groceries\&notes=Bought%20fruits%20and%20vegetables\&account=test"

Using links

You can click links and open them with Cashew. See the example section above to test.

Make sure you are in application root directory
- cd .\budget\
Generate database code

Export the new schema
- Generate schema dump for the newly created schema
- Replace [schemaVersion] in the command below with the value of schemaVersionGlobal
- Run dart run drift_dev schema dump lib\database\tables.dart drift_schemas//drift_schema_v[schemaVersion].json
- Read more: https://drift.simonbinder.eu/docs/advanced-features/migrations/#exporting-the-schema
Generate step-by-step migrations
- Run dart run drift_dev schema steps drift_schemas/ lib\database\schema_versions.dart
Implement migration strategy
- Edit await stepByStep(...) function in tables.dart and add the migration strategy for the new version migration

Get Platform

Use getPlatform() from functions.dart
Since Platform is not supported on web, we must create a wrapper and always use this to determine the current platform

Push Route

If we want to navigate to a new page, stick to pushRoute(context, page) function from functions.dart
It handles the platform routing and PageRouteBuilder

Wallets vs. Accounts

Wallets have been been renamed to Accounts on the front-end but internally, the name Wallet is still used.

Objectives vs. Goals

Objectives have been been renamed to Goals on the front-end but internally, the name Objectives is still used.

Long Term Loans

Long term loans create a goal. However, the goals total is not used. Instead the total of the goal is calculated by totalling the proper polarity of transactions of the opposite type. For example, if it was a loan of 100$ lent out, the initial transaction would be 100$ of negative polarity (expense) and that would be the total of the goal. When a payment is made, it is made in the opposite (positive) polarity (income) and added to the total 'paid back'. We can easily find how much is remaining by taking the difference (or the addition including polarities).
