PriceProof 30
Show the real 30-day low price
The EU Omnibus Directive requires a shop announcing a price reduction to state the lowest price that applied in the preceding period — usually 30 days. Shopify does not keep price history, so that figure does not exist anywhere in the admin. PriceProof 30 records every price change on every variant, works out the lowest price actually in effect over the last 30 days, and shows it under the price on the product page.

UnitProof
Unit prices, without the spreadsheet
UnitProof finds the variants in a Shopify catalog whose price per kilo, litre, metre, square metre or item is missing or wrong, works out the right measurement from what the store already knows, and writes it across the catalog in one go — into Shopify's own unit price fields, so the theme shows it without any change. Built for merchants who sell by measure: food, drink, cosmetics, cleaning products, building materials.

CartMotion
Make Add to cart feel like something happened
CartMotion flies the product's own photo into your cart icon, nudges the cart, and confirms on the button — on the theme you already use. It never performs the add itself and never alters what the theme sends: it waits for a successful add, then animates. A failed or sold-out add shows nothing.

About
Alex Commerce Labs builds focused Shopify apps — small, well-made tools that do one job honestly. PriceProof 30 keeps the price history Shopify doesn’t. UnitProof fills in the unit prices a theme is already built to show. CartMotion gives shoppers proof that their click landed.
Three different problems, the same approach: read the store’s real data, do the necessary work, and never claim more than an app can actually prove.
