About this app

Don't lose a penny from the bottle vending machine!

Butlo is a free app that helps you manage your coupons from the Polish deposit-refund system. After returning PET bottles, aluminum cans, or glass cans to the bottle vending machine, you receive a receipt-coupon with the amount to be used in the store. Butlo ensures that not a single one expires unused.

🍾 WHY BUTLÓ?

A deposit-refund system has been in operation in Poland since October 1, 2025. For PET bottles, glass bottles, and cans, you'll receive a refund of 0.50 groszy (PLN 1). However, coupons have an expiration date, and they can get lost in your wallet or tucked away between receipts. Butlo solves this problem in 30 seconds.

📷 SCAN A COUPON WITH YOUR CAMERA
All you need is a photo of the receipt. Butlo automatically reads the amount, expiration date, and store—Lidl, Biedronka, Żabka, Kaufland, Carrefour, Auchan, Netto, Dino, and others. No need to enter anything manually.

💰 WALLET WITH A TOTAL TO BE USED
On the home screen, you can see exactly how much złoty you have in coupons—ready to spend on your next purchase.

A list of coupons is sorted by expiration date: those that expire the soonest are at the top.

🔔 EXPIRY REMINDERS
We'll notify you 7 days before, 2 days before, and on the coupon's expiration date. Configurable—disable if you prefer peace of mind.
Notifications work even without internet.

🛒 SHOW CODE TO CASHIER
Open the coupon at checkout—Butlo will display a large barcode or QR code, and the screen will automatically brighten for easy scanning. After redeeming it, you mark the coupon as redeemed with a single tap.

📊 SAVINGS STATISTICS
Check how much money you've saved from the bottle vending machine in total. See how many PET bottles and cans you've already returned. Which store
you visit most often. Everything in one place.

🗺️ BOTTLE VENDOR MAP
Find the nearest bottle vending machine on the map. We'll show you stores in your area—Lidl, Biedronka, Żabka, and other chains—that accept packaging.

☁️ CLOUD SYNC (optional)
Log in with email or your Google account—your coupons will be securely synced between phones.
Switching phones? Your coupons will transfer automatically. Prefer locally? The app also works without an account—fully offline.

🌱 YOU ARE DOING FOR THE PLANET
Every bottle you return goes back into circulation instead of ending up in a landfill. Butlo shows how many bottles you've already returned—your personal contribution to the circular economy.

⚙️ SIMPLICITY AND PRIVACY
No unnecessary screens, no need to create an account (unless you want to sync). We store your receipts locally.

Location data is only used when using the map—we never send it anywhere.

📱 REQUIREMENTS
Android 6.0 (Marshmallow) or newer. Camera access—only for scanning receipts (Butlo never sends photos to the server without your consent).

💡 PERFECT FOR:
• People who regularly use Lidl, Biedronka, Żabka, and Kaufland bottle vending machines
• Families who circulate coupons
• Those who want to make real savings
• People who value simplicity and Polish apps

Bottle is a small tool that makes a big difference—so you don't waste a penny on the deposit system anymore. Try it—the first scan will take 30 seconds.
