When it comes to saving money on gas, two apps dominate the conversation: Fluz and Upside. Both help drivers earn cashback at the pump, but they do it in very different ways. Whether you’re a daily commuter, a rideshare driver, or someone looking for fast, reliable fuel savings, choosing the right app can make a big difference in how much—and how easily—you save.

Here’s a side-by-side breakdown of Fluz vs. Upside, including pros, cons, speed, supported merchants, and who each app is best for.

Fluz: Instant Cashback and Prepaid Convenience

Fluz works by offering instant cashback when you purchase digital gift cards for gas stations. You can buy gift cards for Chevron, Texaco, Shell, and Speedway, and use them immediately at the pump or inside the station.

Pros:

• Cashback is instant—no waiting or receipt scanning
• Great for drivers who want to preload fuel budgets
• Works with most gas station loyalty programs, so you can stack rewards
• Frictionless experience for repeat use

Cons:

• Requires knowing your spending amount before purchase
• Limited to gift card-eligible merchants (no location-based discovery)

Best for:

• Commuters who refuel at the same stations regularly
• Rideshare and delivery drivers who want predictable savings
• Budgeters who want to preload gas money weekly or monthly

Upside: Location-Based Offers with Receipt Uploads

Upside helps users find nearby fuel deals based on their location. After claiming an offer, you fill up at a participating gas station, pay with a linked card or upload a receipt, and receive cashback later.

Pros:

• Discover offers from a variety of gas stations in real time
• Great for on-the-go drivers who don’t always use the same station
• Can stack with fuel rewards programs (when paying with a card)

Cons:

• Cashback can take several days to post
• Requires claiming an offer in advance and uploading a receipt
• Doesn’t work as seamlessly if using a gift card or unlinked payment

Best for:

• Long-distance drivers or travelers
• Drivers who value flexibility over routine
• Those who regularly check for local gas deals

Fluz vs. Upside: Which App Saves You More Time?

If speed and simplicity are your priorities, Fluz wins for instant cashback and a clean, prepayment-based workflow. Buy a gift card, use it, and get your savings immediately—no scanning, no waiting.

If you prefer flexibility and nearby deals, Upside is better for discovering new stations with competitive prices, especially when you’re in unfamiliar areas or during road trips.

Final Verdict: Use Fluz for Speed, Upside for Flexibility

• Choose Fluz if you want predictable savings, preloaded fuel budgeting, and instant cashback at stations like Chevron, Shell, and Texaco. Download Fluz here to get started.
• Choose Upside if you want on-the-fly gas deals and don’t mind uploading receipts or waiting a few days for your rewards.

Some drivers even use both—Fluz to preload and save at favorite stations, and Upside to take advantage of extra deals when traveling.
