How SizeEcho sells itself on the App Store
The pitch, integrations and features merchants see before they install: the positioning a competitor is betting on.
“SizeEcho collects fit answers after shipping. See which products and sizes run small or large.”
What it does
SizeEcho shows apparel merchants which products and sizes run too small, true to size, or too big, using buyer answers after an order ships. After fulfillment it waits a delay you set, then sends one event to Klaviyo. Your Klaviyo Flow emails the fit check-in.… SizeEcho shows apparel merchants which products and sizes run too small, true to size, or too big, using buyer answers after an order ships. After fulfillment it waits a delay you set, then sends one event to Klaviyo. Your Klaviyo Flow emails the fit check-in. Answers land in Overview, Products, and Sizes so you can improve size guides and product copy. Requires Klaviyo. SizeEcho does not email buyers itself. Billing uses Shopify Billing.

Seen on the storefront, not guessed
If Shoplist shows SizeEcho on a store, it’s there. Every count on this page traces to code found on a live storefront, re-checked on every crawl.
Code-level
Found in the storefront’s own code
Shoplist matches the scripts, app blocks and pixels SizeEcho loads on each live storefront. No surveys, no developer-reported numbers, no model guessing installs from review counts.
Re-checked, so the count stays current
Shoplist keeps crawling the same storefronts. A store that uninstalls SizeEcho leaves the count on the next crawl, so you read today’s install base, not a high-water mark.
Daily
The App Store, read every day
Rank, reviews, pricing and every listing edit are captured daily, so a price change or a ranking slip shows up here the day it ships.
Two public sources, labelled on every section. Store data last checked .
