Keeping track of how much you’re spending on gas each month doesn’t have to mean spreadsheets, receipts, or guesswork. With just your smartphone and a few easy-to-use apps, you can monitor fuel expenses, spot trends, and manage your budget—whether you’re tech-savvy or just looking for a straightforward solution. For families, commuters, and older drivers alike, digital fuel tracking can be both simple and stress-free.

Here’s how to track fuel spending with your phone, and the best beginner-friendly apps to help you do it.

Log Gallons and Costs Automatically with Fuelly

Fuelly is one of the most trusted apps for tracking gas mileage, fill-ups, and fuel costs over time. It’s designed to be simple: after each trip to the pump, you log how many gallons you filled and what you paid. Over time, Fuelly calculates your miles per gallon (MPG), monthly spending, and long-term cost trends.

Why it’s easy:

• Tap in data manually or use odometer readings for better accuracy
• View charts that show fuel economy and expenses over time
• Great for tracking multiple vehicles in the same household

If you’re new to fuel tracking, set a weekly reminder to log each receipt or fill-up. It takes less than a minute and helps you build a full picture of your driving habits and fuel usage.

Use Fluz to Log Prepaid Fuel Spending and Earn Cashback

If you want your fuel spending to stay within a set monthly limit—and get rewarded for sticking to it—Fluz is a smart tool. It lets you buy digital gift cards for major gas stations like Shell, Chevron, Texaco, and Speedway, and gives you instant cashback on every purchase.

Why Fluz helps with tracking:

• Your transaction history shows exactly how much you’ve spent on gas
• Cashback rewards can be tracked in-app
• Helps households set a prepaid fuel budget, especially helpful for teens or multi-driver families

Instead of monitoring random card charges, you can clearly see how much gas money was spent, where it went, and what you earned back.

Use Ibotta to Offset Fuel Costs Through Grocery Tracking

Ibotta isn’t a fuel tracking app—but it’s a useful companion for anyone trying to free up more money for gas. It rewards you with cashback on everyday grocery purchases, which you can use to indirectly offset your fuel spending.

How to tie it in:

• Use Ibotta to track your grocery savings
• Set an alert or weekly reminder to cash out every month
• Move those savings into your gas budget or use them to buy gas gift cards via Fluz

Pairing Ibotta with Fluz is a great way to stretch your budget, especially for families trying to manage fuel and food expenses at the same time.

Best Practices for Simple Fuel Tracking

• Set a recurring reminder on your phone every Sunday to check in with your spending
• Use one primary card or gift card source (like Fluz) for easier tracking
• Log every fill-up in Fuelly to see MPG trends and spot if something changes with your car’s efficiency
• Review your total monthly spend and adjust your driving habits or budget if needed

Final Thoughts

Tracking fuel spending doesn’t have to be complicated. With beginner-friendly tools like Fuelly for MPG tracking, Fluz for prepaid budgeting and cashback, and Ibotta for offsetting costs, you can take control of your fuel finances with just a few taps a week.
