I Created My Own Android Expense Tracker After Finding All the “Free” Apps Required Subscriptions

Subscriptions have become ubiquitous in our daily lives, covering everything from video streaming and meal planning to calculator apps. Regardless of their purpose, many apps now impose fees for additional features.

This trend extends to financial management tools, which are ironically designed to help users save money but often charge for full functionality. Frustrated with these money-grabbing tactics, I decided to create my own expense tracker rather than pay for an app.

I’ve moved away from costly tracking apps

Hidden costs for feature-rich applications

It is rare to download an app these days without being presented with promotional offers for premium features upon registration or at login. Enhanced customization options and advanced functionalities, like AI capabilities, are typically locked behind a paywall.

Often, you won’t even discover these fees until you attempt to access a feature and find it unavailable without a subscription. This is particularly ironic for expense-tracking apps, which claim to help you manage your spending while charging more than the expenses they seek to track.

In my exploration of expense-tracking apps—Monefy, MyMoney, and Money Tracker—all had subscription tiers, limiting my access to features either upfront or through hidden menus. Frustrated, I set out to build my own tracker instead.

Assembling my own expense tracker

Collecting expenses into a manageable format

When designing my expense tracker, my aim was simplicity and ease of access, avoiding complexity that makes data entry tedious. I sought a completely free tool that would allow me to customize my view without encountering paywalls.

Google Sheets became my tool of choice since I can access it easily across devices—be it my phone, tablet, or computer—simply through my account. Its pivot table feature allows me to format my expenses as needed.

Structuring my tracker

The first step was to create a template named “Expense Tracker 2026.” While I considered using one sheet for multiple years, I aimed to create a separate sheet for each year in order to maintain performance.

I established five categories as columns: Month, Date, Expense, Category, and Amount. The Month, Date, and Amount columns are straightforward, while the Expense column denotes the purchase item, and the Category column specifies the type of bill, such as entertainment or groceries.

Currently, my entries focus on a single credit card I wish to monitor closely. Although I could add a “Card” column, it’s not necessary since I’m tracking just one card.

Creating the pivot table

The pivot table might seem complex, but its utility and customization options make it worthwhile. However, note that you can only create and modify pivot tables on a desktop, not through the mobile app.

To initiate one, I clicked on Insert in the main menu and selected Pivot Table. The system prompted me to specify my data range and where I wanted to place the pivot table.

I chose to create the pivot table on a separate sheet to avoid clutter. I selected columns A through E for the data range so that as I add expenses, the pivot table would automatically update.

Once created, I renamed the sheets for clarity—labeling the expense data “Expenses” and the pivot table simply as “Pivot Table.”

A pivot table is far more flexible than a simple sum formula, allowing me to arrange my data in myriad ways.

For instance, by moving the Category column into the Rows section and the Amount column into Values, I can now see total expenditures for each category throughout the year.

Should I want to examine totals by category further, I can easily add the Months under the Category section, and the display will refresh with this breakdown.

All future input will continue to flow into the pivot table since I’ve configured it to encompass the entire column. This means I won’t need to adjust the pivot table settings every time I enter new data; it will adapt automatically.

Managing my expenses effectively

This approach provides a straightforward yet cost-effective method for tracking expenses. All the features I utilize will remain free for the foreseeable future, ensuring perpetual access to my expense tracker.

If you share my aversion to unexpected subscription fees, consider using Google Sheets to keep your financials organized. With the aid of a pivot table, you can create a sustainable expense tracker that won’t burden you with future costs.
