Scan any product and instantly see every coupon and cashback offer for it — then watch the savings apply automatically at checkout. Shopper Sentinel catches shrinkflation, stacks your discounts, and finds the truly cheapest store. We work for you, never the seller.
Prices creep, packages shrink, "sales" aren't really sales, and the coupons you're owed are scattered across a dozen apps. Shopper Sentinel turns all of that into one calm, honest answer.
Brands quietly cut sizes while holding the shelf price. We catch it and show you the per-ounce truth.
That big red tag is often the same price it's always been. We compare it to the real 90-day history.
Coupons, cashback, and loyalty offers live in different places. We gather every one into a single scan.
Point your camera at any product barcode — in any store, anywhere you shop. No typing, no hunting.
Every digital coupon, cashback offer, and loyalty price for that exact product — gathered into one clean view, ranked by real value.
We clip the offers to your store loyalty account, so they apply on their own at checkout. One barcode at the register — every saving, applied.
Built to do the things no single app does together — and to do them honestly.
We catch products that quietly shrink while the price holds — and show you the evidence. Real per-ounce truth, never outrage.

Find the store brand that's the name brand in disguise, smarter swaps, and allergen-safe alternatives.
Diabetic, heart-healthy, low-sodium, allergen-aware, pregnancy, and caregiving modes — shopping that respects your health.
Real-time shared lists, a family budget mode — even managing a parent's groceries from across the country.
Most shopping apps quietly work for whoever pays them. We made the opposite promise — and built the whole product around keeping it.
No countdown timers. No "12 people are looking at this." No manufactured panic. Our confidence comes from being right, not loud.
Every claim has a receipt — literally. When we flag a shrink or a fake sale, we show you exactly where we saw it.
We hold retailers and brands to account with facts, not outrage. We describe the behavior and let you decide.
When something is sponsored, we say "Sponsored," plainly, every time — and still show you the cheaper option below it.
Open Beta is the real launch — free, and improving in the open. Here's the order things roll out. Honest about what's first, ambitious about where it goes.
Shopper Sentinel runs on official partnerships and full disclosure — coupon networks, loyalty programs, brands, and retailers who want to reach shoppers honestly. If that's you, we should talk.
Join the founding list. When the free Open Beta opens, you'll be first through the door — and you'll help shape the most honest shopping app ever built.
