We make one of the apps on this page, so read it with that in mind. Prices and features of other apps come from their Shopify App Store listings, checked on November 14, 2026. Plans change: check the listing before you decide.
On this page
KNO (by KnoCommerce) is a survey platform built around attribution and customer research, with industry benchmarks and integrations with analytics tools. HearAbout, our app, does the attribution survey on the Thank you page and keeps the results in Shopify.
The short version
- Pick HearAbout if you want an attribution question with a few follow-ups, sales by channel, and order tags, without the 3-question limit of a $19 plan.
- Pick KNO if you want benchmarks against other brands, email or SMS surveys, or integrations with tools like Triple Whale, Peel or Klaviyo, and the Analyst or Pro price works for you.

What KNO does that HearAbout doesn’t
- Benchmarks against other stores (Analyst and up).
- Email and SMS surveys, and survey links (Pro).
- Analytics integrations listed on the App Store: Google Analytics, Klaviyo, Peel Insights, ReCharge, TikTok, Triple Whale and Shopify Flow, plus a REST API.
- 30+ survey templates and dozens of pre-built questions.
- A track record: on the App Store since October 2020, 4.9 from 119 reviews.
What HearAbout does differently
- Answers on the order. Each answer becomes an order tag like
hdyhau:tiktokand is saved in an order metafield, so you can filter orders in Shopify without opening the app. - Last click comparison. Results show what buyers say next to the last click Shopify recorded, so you see which channels your pixels undercount.
- Value after 90 days per channel, from Shopify’s customer ID, for buyers with customer accounts.
- Built for Shopify badge.
If you’re on KNO Starter
The usual pain is the 3-question limit: attribution, one follow-up, and you’re out. In HearAbout the same survey can have the attribution question, a “Which creator?” follow-up, a “What almost stopped you?” question for new customers, and NPS for returning ones, each shown only to the buyers it’s meant for.
Switching
Export your KNO responses first. In HearAbout, name your answers the same way, run the new survey and turn KNO’s off on the same day, and keep a note of the switch date for your reports.
