About this app

Price Comparison PRO was created to answer a simple question that arises with almost every purchase: "Which packaging is really worth it?" The largest "economical" label doesn't always represent the best cost per base. The app standardizes prices and delivers an objective answer, with data you can verify.

A shared shopping list allows for fluidity when shopping.

Clarity above all: we show the price per base, the absolute difference in reais, and the percentage savings.

Real flexibility: units designed for everyday use (UN, M, g, kg, ml, L) and a Package mode for handling boxes or kits (indicating "units in package" and "contents per unit").

Quick decision: flow in just a few taps—add product, enter price/quantity, calculate.

Accessible: Material 3 interface, legible typography, and comfortable spacing.

Detailed Use Cases

Monthly Market: Compare "refill" vs. "traditional" versions, family vs. individual versions, different brands with different weights/volumes.

Wholesale/Retail: Understand if a large box is worth it even when compared to individual unit promotions.

Construction and Stationery: Measure materials sold by the meter (tapes, cables, hoses) in Unit (M) mode.

Capsules, Sachets, and Kits: In the Package, enter the number of units and the content per unit (g/ml). The final price is standardized for the chosen base.

Dynamic List: Add multiple products; each card accepts name, price, quantity, and unit.

Unit Chips: Quickly switch between g/kg, ml/L, UN/M depending on the mode.

Quick Actions: Calculate, Clear, and Remove buttons.

Explanatory Result: Final panel with Winner, Price per base, Difference (R$), and Savings (%) — ready for decision-making. Calculation Accuracy

Inputs accept decimals (e.g., 1.5 L; 0.75 kg).

The result is rounded only when displayed, preserving internal precision.

Base values ​​use standardized conversions (1 kg = 1000 g; 1 L = 1000 ml).

Privacy, Connectivity, and Ads

Calculations and logic work offline.

Internet is required only for ads and purchase validation (ad removal).

We do not require a login. We do not collect personal data to use the comparison features.

Fair Monetization

Ads appear moderately.

There is a one-time purchase option to permanently remove ads from the device.

Support and Roadmap

We value feedback on additional units, accessibility improvements, and new comparison modes.

Problems, ideas, or suggestions can be submitted through the designated channel within the app.

Results depend on the values ​​entered. Always check that price and quantity are entered correctly.
