Cashback apps promise the same thing: pay for stuff you were already going to buy, get a slice of the money back. What trips beginners up is that each app earns its cashback in a completely different way — and using the wrong app for a given purchase leaves real money on the table. Here's the plain-English breakdown of the four apps most people start with.
Rakuten — the online shopping portal
Rakuten is a shopping portal. You open the Rakuten app or browser extension before checking out at a supported store, click through to the retailer, and Rakuten earns an affiliate commission that it splits with you. Rates typically run 1%–10%, with regular promos pushing certain stores to 12%+.
- Best for: online orders at large retailers (department stores, electronics, travel).
- Payout: cash via PayPal or check, usually quarterly.
- Watch out for: forgetting the click-through — no click, no cashback.
Ibotta — the receipt & offer app
Ibotta pays you for specific products, mostly at grocery stores, drugstores, and big-box retailers. You browse offers in the app before shopping, buy the qualifying items, then either scan your receipt or link a loyalty account so Ibotta can verify the purchase.
- Best for: groceries, household staples, and brand-name products.
- Payout: cash to PayPal/Venmo or gift cards once you hit the $20 minimum.
- Watch out for: offers that require you to 'add' them before purchase — miss that step and the receipt won't credit.
Fetch — the passive points app
Fetch is the easiest of the four. Scan any grocery, restaurant, or retail receipt and Fetch awards points — no offer selection required. You earn extra points for participating brands, but you get something for every eligible receipt.
- Best for: shoppers who want zero-effort rewards on receipts they'd throw away anyway.
- Payout: gift cards (Amazon, Target, Walmart, Visa, and hundreds more).
- Watch out for: the exchange rate — Fetch points are worth roughly $0.001 each, so treat it as a bonus layer, not your main app.
Upside — the gas & food app
Upside pays cash back on gas, groceries, and restaurants. You claim an offer in the app before you pay, then pay with a linked credit or debit card at the participating location. Upside verifies the transaction automatically.
- Best for: gas fill-ups (often 15¢–25¢ per gallon back) and local restaurants.
- Payout: cash to bank, PayPal, or gift cards — no big minimum.
- Watch out for: expiring offers. Claim in-app before you swipe or you get nothing.
Which app should you install first?
You don't need all four on day one. Pick based on how you actually spend:
- Mostly shop online? Start with Rakuten.
- Big weekly grocery run? Start with Ibotta.
- Drive a lot? Start with Upside.
- Want the lowest-effort option? Start with Fetch.
Using them together (the easy way)
The apps don't compete — they layer. A typical week for someone using all four looks like this:
- Online orders → Rakuten click-through, then pay with your best cashback credit card.
- Grocery run → activate Ibotta offers before shopping, scan the receipt in Fetch afterward.
- Gas fill-up → claim the Upside offer before swiping.
- Restaurants → check Upside first; scan the receipt in Fetch after.
That's it. Two clicks and a receipt scan turn ordinary spending into a steady rebate stream. If you want to see how these apps compare to browser-based shopping portals, our guide to cashback apps vs. portals walks through exactly when each one wins.
