With gas prices frequently on the rise, cashback apps have become a go-to strategy for cost-conscious drivers looking to cut down on fuel expenses. Two of the most popular platforms in this space—Fluz and Upside—offer distinctly different approaches to savings at the pump. If you’re wondering which is better for your driving habits, here’s a side-by-side look to help you decide.
How Fluz Works
Fluz offers instant cashback when you purchase digital gift cards for gas stations and other retailers. Instead of paying directly at the pump with your debit or credit card, you buy a gift card in the app and use it as your form of payment—online or in person.
Fluz offers instant cashback after purchase and works seamlessly with many fuel rewards programs. There’s no scanning, receipt upload, or waiting period.
How Upside Works
Upside offers cashback when you shop or get gas at partnered locations. You claim offers in the app before purchasing, then submit a photo of your receipt or use a linked card for automatic verification.
Gas stations available through Upside vary by location and often include regional chains. The app regularly promotes higher cashback percentages for first-time visits or bonus locations.
Where Fluz Wins
- Instant Cashback: No need to upload receipts or wait days for cashback to process
- Wide Brand Access: Supports major national gas chains
- Stackable with Rewards: Works with Shell Fuel Rewards or Kroger Fuel Points
- More Control: Choose your cashback rate based on the gift card you buy
Where Upside Wins
- Location-Based Offers: Cashback offers are targeted to your zip code or GPS location
- No Upfront Purchase: You can pay with any method and still get cashback (as long as the purchase is verified)
- Good for In-Store Combos: Offers cashback on fuel, convenience store items, and restaurants
Potential Drawbacks
- Fluz requires you to buy a gift card first, which may not work well for spontaneous drivers
- Upside requires receipt uploads or linked card usage, which can delay cashback and reduce privacy for some users
Which App Saves More?
It depends on your habits. If you’re a planner who knows where and when you fill up, Fluz offers predictable, stackable cashback with no extra steps. If you prefer on-the-go flexibility and don’t mind snapping receipts, Upside may occasionally offer higher rates—especially for first-time visits or during promotions.
Many savvy drivers use both apps—Fluz for guaranteed base savings on gift card purchases, and Upside for occasional high-percentage offers.
Final Thoughts
Both Fluz and Upside offer real savings at the pump, but they cater to different styles of budgeting. Fluz is best for intentional spenders who want control and speed, while Upside is better for drivers who prefer passive, location-based offers. Whichever route you choose, you’ll be paying less than the car next to you.
