Compratron

No more finding out the price at the checkout.

Compratron is the app that transforms your trip to the supermarket into a smart decision. Make your list, share it with your family, and see, in real time, how much each product costs in supermarkets near you — informed by the community itself.

------ WHY COMPRATRON ------

• A LIST THAT SURVIVES THE SHOPPING CART
Create lists, organize by category, mark what you've already bought, and never forget that item that always gets left out again.

• SHARE WITH THOSE WHO MATTERS
Send the link and your family, partner, or housemate can edit the same list with you. Everything synchronized.

• REAL-TIME PRICES FROM THE COMMUNITY
Every purchase that enters the app feeds a collaborative price database. See where bananas are cheapest TODAY, without having to go to three different supermarkets.

• SCAN THE RECEIPT AND YOU'RE DONE
Read the QR Code on the receipt? Done. Compratron imports all items, with name, price, unit, and market. No typing required.

• HISTORY THAT BECOMES A REPORT
Track the price evolution of each item in each market. See if milk went up, if rice went down, and make decisions based on data, not guesswork.

• SHOPPING MODE THAT CALCULATES
Going to the market? Activate Shopping Mode: mark each item, record the price per kg, liter, dozen, or package, and watch the partial total rise as you walk through the aisles.

• POCKET ARTIFICIAL INTELLIGENCE
Suggestions for items you usually buy, waste alerts, recipes using what's already on your list — all via AI, within the app.

• MAP AND MARKETS
Find nearby supermarkets, see community reviews, and discover prices before even leaving home.

------ WHY IT'S DIFFERENT ------

Other apps charge to show prices. Compratron does the opposite: the system is COLLABORATIVE. The more you use it, the more the community benefits — and the more the community grows, the better your prices become.

And more: the NFC-e (electronic tax receipt) is FREE for everyone. Scan, import, contribute — no paywall.

------ PREMIUM (optional) ------

Want more? The Premium plan unlocks:

• Unlimited price history
• Advanced reports by market and by item
• No ads
• Unlimited lists
• Priority support

Your purchase remains private — Premium is yours, but the pricing system remains collaborative.

------ PRIVACY THAT RESPECTS ------

Your list is yours. We don't sell your data, we don't track your cart. Compratron is designed in compliance with the LGPD (Brazilian General Data Protection Law): you decide what to share, and you can delete everything at any time.

------ MADE FOR BRAZIL ------

The Brazilian market has its peculiarities: electronic sales receipts, weight by weight, dozens at the produce section, and the exchange rate (R$) that changes every week. Compratron was designed from start to finish for this.
