How does the 'This or That' comparison math work?

The tool uses two distinct metrics: 1) Cost Per Unit (mathematically dividing Price by Quantity/Weight), and 2) A Weighted Value Score. The Value Score combines the raw price efficiency with your custom Desirability Rating (1-10 scale), penalizing more expensive options to show you if a slightly lower quality product is worth the massive discount.

Can I upload screenshots of menus, Amazon deals, or store flyers?

Yes! You can drag and drop or upload image screenshots for both Deal A and Deal B. The images are processed 100% locally in your browser's temporary storage, allowing you to easily visual-match products and see their flyer specifications side-by-side.

Is my shopping data kept private?

Completely. ToolzMoolz operates 100% client-side. All pricing numbers, weight inputs, brand titles, and uploaded deal images are handled locally in your browser's execution memory. No details are ever sent to a server, keeping your shopping lists completely private.

Our browser-based value auditor and deals comparison matrix is the ultimate shopping calculator. Retailers regularly list pricing schemas (like '2 for £3', '500g for £4.50') to make it difficult for shoppers to perform fast math in their heads. By mapping price details side-by-side and incorporating a **subjective Desirability/Quality multiplier**, this tool calculates exactly which option delivers superior value. Upload screenshots of restaurant flyers, grocery deals, or Amazon items, and immediately audit costs to save up to 30% on your purchases.

Step-by-Step Instructions:

Upload Screenshot: Click the uploader panels to load images of Amazon deals, flyer cards, or McDonald's vs KFC menu deals.

Frequently Asked Questions (FAQ)

What is a 'Smart Value Score'?

The Smart Value Score is a mathematical index out of 100. It multiplies your quality rating by the ratio of the cheapest unit cost to the product's unit cost. This means that a cheaper unit price boosts the score, but a highly rated product can still win if the cheaper option is extremely poor quality.

Should I ensure measurement units match?

Yes. The tool automatically synchronizes measurement units for comparison (e.g. if you select 'kg' for Option A, it sets 'kg' for Option B). This guarantees a correct mathematical side-by-side unit cost calculation.

Does this tool work on mobile while shopping in a store?

Yes! The entire webpage layout is mobile responsive and performs all mathematical checks inside your browser instantly without loading data. You can take photos of shelves and calculate deal savings in real-time inside the supermarket.
