Why You Need a Financial Application—and Why I Built my own

Financial decisions today are increasingly complex and in a world where every dollar counts, keeping track of your money is more important than ever. Budgeting applications are essential for managing money, monitor spending, set financial goals, and ultimately build a better relationship with money. But with many apps on the market, each with its quirks, subscriptions, and limitations, how do we choose?

Let’s explore why budgeting apps are important and why I chose to build my own.

Why You Need a Budgeting App

1. Gain Control Over Your Finances
Most people including me had a vague idea of their financial situation (bad) until they start tracking it. Budgeting apps should provide clarity by showing you exactly where your money goes. Whether you're trying to pay off debt, save for a big purchase, or stop living pay check to pay check, tracking your finances is the first step.

2. Set and Track Goals
Want to save $200k for a down payment? Cut your food spending by $20? A budgeting app makes goal-setting tangible, allowing you to break your big dreams into manageable steps and monitor your progress over time.

3. Eliminate Mindless Spending
Seeing daily, weekly, and monthly spending patterns in real time helps cut back on impulse buys. Once you recognise patterns (e.g. too much takeout, unused subscriptions), you can change behaviour and reallocate funds toward things that truly matter.

4. Automate and Simplify
Manually tracking expenses in a notebook or spreadsheet can work but it painful and confusing quickly. Apps automate data entry, categorise expenses, and may even pull in transactions from your bank or credit card, making it easier to keep up with your budget.

Why You Should Build Your Own Budgeting App

While apps like YNAB, Frollo, and EveryDollar are popular for a reason, they’re not without downsides. Building your own budgeting application gives you total control and offers several benefits that off the shelf apps just can’t match.

1. You Can Build the Features You Need
Most budgeting apps try to serve a broad audience. As a result, they often include features you’ll never use or leave out the ones you desperately need. Maybe you need envelope style budgeting but with crypto integration. Or maybe you want a visual calendar view of your cash flow. When you build your own app, you build what you need.

With Yafa I wanted a couple of features in particular. I wanted unlimited accounts, unlimited categories, take actions based on categories and the like. This was not something available to me with the other apps.

2. Say Goodbye to Monthly Fees
Many top-tier budgeting tools come with subscription fees ranging from $5 to $15 a month. That might not seem like much, but it adds up—especially when the whole point is to save money. Building your own app is a one-time investment of time and (possibly) some initial setup cost, but it can save hundreds over the years.

Yafa is built to be free. I have minimised all my costs for running the application. Its sits behind Cloudflare, it runs on a cloud provider, where costs are amortised over the multiple services I run. To me the costs of running an application are minimal to non-existant. The true cost is my time and for various reasons deploying Yafa is well worth the trouble.

3. Learn Valuable Skills
Even if you’re not a professional developer, creating your own budgeting app is a great way to learn programming, data structures, API integration, and UX design. It’s a practical project with real-world value.

4. Integrate With Your Life Seamlessly
Want to pull data from your custom bank API? Sync it with your calendar? Add voice command capabilities? Building your own app means you’re only limited by your creativity. You can integrate your budgeting tool into your digital ecosystem in ways no third-party app ever could.

I don’t want to sync with my bank accounts, but I want the ability to search my data and make connections via search. By having access to the database I can do this. By building it as a feature I can give anyone thsi power.

What You’ll Need to Get Started

• Tech Stack: Depending on your skills, you can use a web-based stack (React, Node.js, Firebase), a spreadsheet-powered backend (Google Sheets + Apps Script), or even a mobile-first approach (Flutter, Swift).

• Budgeting Features: Think categories, recurring expenses, goal tracking, graphs, and reporting.

• Security: Implement strong encryption and consider offline storage or local hosting to ensure your data stays secure.

• UI/UX: Clean design is crucial for daily usability—don’t skip on making it intuitive and visually appealing.

Over the coming weeks I will get into a technical deep dive of how I built Yafa, how to use it, its quirks, its features and ultimately why I think you should use it.
