Three apps, two different mechanics — here’s how Upside, Receipt Hog, and CoinOut actually compare, and why running all three beats picking just one.
Cash-back apps fall into two rough types: ones that give you a discount on a specific purchase before you pay, and ones that reward you after the fact just for scanning a receipt you already had. Both are worth using — they stack.
| App | Best for | Current offer | Payout method |
|---|---|---|---|
| Upside | Gas, restaurant & grocery cash back | 15¢/gal + 10%* | PayPal, bank, gift card |
| Receipt Hog | Any-store receipt scanning | Bonus on 1st upload* | PayPal, gift card |
| CoinOut | Quick receipt scans, no purchase needed | Per-receipt coins | Cash, gift card, charity |
If you drive regularly, Upside is the one to install first. You claim a deal in the app before you pay, so the cash back is locked in ahead of time. It only works at participating locations, so check the map for your area first.
Receipt Hog covers the gap Upside leaves: it takes receipts from almost any store. Per-receipt rewards are small change, not a discount on the purchase itself.
CoinOut works similarly to Receipt Hog. Running both isn’t redundant — scanning into both takes the same five seconds and can add up faster than either alone.
Stacked together, these apps typically add up to modest monthly cash back — real money for close to zero extra effort, but not a meaningful income stream on their own.
