Dwindl tells you everything you need to know about a product before you put it in your cart — shrinkage history, price fairness, unit price math, and better alternatives. All in a two-second scan.
Coming soon to iOS and AndroidOpen Dwindl, point your camera at any barcode. In under two seconds, you get the full story — not just whether it shrunk, but whether you're getting a fair deal. No account required. No setup. Your first scan happens within ten seconds of opening the app.
Every scan returns a Dwindl Card. One screen with everything that matters:
The ScoreA number from 0 to 100. Green means clean. Red means you're getting less.
Size History15.4 oz in 2019. 14.0 in 2022. 13.0 today. The full timeline.
Fair PriceGreen check is fair. Amber means you could do better. Dwindl does the math.
Unit PriceYou're paying $0.33/oz. The 18 oz box is 15% cheaper.
The SwapWhen a product scores badly, Dwindl suggests real alternatives.
After your first scan opens a full card, every scan after that shows a compact result — product name, score, and a one-line verdict. Tap to see more. Most scans take two seconds. Scan ten products while you wait in the checkout line.
Add any product to your Shelf after scanning it. Dwindl monitors everything on your Shelf — size changes, price hikes, value shifts. When something changes, you get a notification. Not a weekly digest. An alert, the moment it happens. 'Charmin just dropped from 224 to 208 sheets.' Your Shelf never sleeps.
When you switch from a shrunk product to something better, tell Dwindl. Your switch gets shown to everyone scanning the same product. When hundreds of people confirm the same alternative, it becomes the top recommendation. This isn't an algorithm guessing — it's 847 people telling you 'I switched to this and it's worth it.'
Dwindl automatically groups your scans by store visit. After each trip, you get a report — how many products you scanned, how much volume you've lost, and where you might save money next time. Over time, your Trip history reveals which stores give you the best value and which ones are quietly charging more.
Every quarter, Dwindl compiles a personal report: how many of your products shrunk, how much extra you're paying, which brands stayed honest, and how you compare to the average user. It's the kind of thing you screenshot and send to your group chat.
You'll get about four notifications a month. A real-time alert when a product on your Shelf changes. A weekly highlight — sometimes the biggest shrink of the week, sometimes a price tip, sometimes a community discovery. And a quarterly report. That's it. No spam. No promotions. Just information you can act on.
Dwindl is launching soon on iOS and Android.
