Where the data comes from
No brand pays us. No sponsorships, no affiliate placements inside the app. Every verdict traces back to one of these sources.
USDA FoodData Central
The federal government's public nutrition and packaging dataset. Its dated branded-food records can provide package sizes used as evidence in Shrunk.
Kroger Products API
Kroger's official developer API. Once you pick a store, Shrunk shows available current shelf price, package size, promotion, and stock status as Kroger reports them.
Open Food Facts
A nonprofit, community-maintained product database, licensed ODbL. It supplies product names, brands, and package photos for items outside the USDA and Kroger catalogs.
Human-verified cases
25 hand-checked shrinkflation cases, each with a cited public source — chiefly Edgar Dworsky's mouseprint.org downsizing archive. Every citation is fetched and must state both the before and the after size for that exact product. No entry ships without a link you can check yourself.
Frequently asked questions
What is shrinkflation?
Shrinkflation is when a product's size or quantity falls while its price stays the same or does not fall in proportion. The result is a higher cost per ounce, sheet, or serving.
What are some examples of shrinkflation in 2026?
Coffee cans, chip bags, toilet paper rolls, ice cream tubs, and paper towels are some of the most common categories. Shrunk's browse feed tracks 25 hand-verified cases, each with a public source — see the full shrinkflation list.
How do I spot shrinkflation at the store?
Compare the cost per unit on the shelf tag and check whether package dimensions or count changed. For supported barcodes, Shrunk shows the dated size evidence available for that product and keeps current store pricing separate.
Is there an app that detects shrinkflation?
Yes — Shrunk. Scan or enter a supported grocery barcode to check available dated package-size records from public datasets, published documentation, and reviewed shopper contributions.
Is Shrunk free?
Yes. Scanning, available size evidence, available current Kroger pricing, the browse feed, and label contributions are free with no account required. Shrunk Pro ($2.99/month or $14.99/year, with a 7-day free trial on the yearly plan) adds the watchlist, alerts, unlimited alternatives, full available history charts, and the savings dashboard.
Which stores show live prices in Shrunk?
Available current pricing, package size, promotion, and stock come from the Kroger Products API for the store you pick. Scanning, available size evidence, and the browse feed work without a selected store.
Does Shrunk track me?
No account, no login, and no ad SDKs. Your watchlist and scan activity are never sold or shared. See the full privacy policy for exactly what data the app touches.
How do I cancel Shrunk Pro?
Open Settings on your iPhone → your name → Subscriptions → Shrunk → Cancel Subscription. Cancel at least 24 hours before the current period ends to stop the next charge; you keep Pro until that period ends. Apple, not us, handles cancellations and refunds.
Does Shrunk verify shrinkflation cases before listing them?
Every case in the browse feed is checked by hand against a cited public source — reporting from mouseprint.org, Consumer World, or a news investigation — before it ships. We fetch the page and confirm it states both the before and the after size for that exact product; anything we can't source that way is removed rather than published. No entry is guesswork.
Free to scan. No account needed.
