What product review apps do
Product review apps ask shoppers for ratings, text, photos and video after a purchase and show them on product pages, in search results and in ad feeds. Most also add moderation, Q&A, review import, and feeds to Google Shopping and social channels.
Who uses them: Shopify and other ecommerce store owners, Brands that rely on social proof and photo reviews, Stores wanting Google star ratings, Brands combining reviews with loyalty or referrals, Agencies migrating reviews between platforms.
Price range: Free plans exist at Judge.me (unlimited reviews), Loox (500 orders), Yotpo and Okendo (50 orders each); Stamped's free status is disputed. Paid entry runs from 15 USD (Judge.me Awesome) and 19 (Okendo Essential) up to 49.99 (Loox Convert), 89 to 169 (Yotpo pricing page; its Shopify listing shows 15 and 119 at the lowest volume) and 199 or more (Stamped reviews per a tracker). Top tiers reach 299 to 299.99 (Okendo Power, Loox Unlimited) and custom quotes for enterprise.
What to check before you buy
Pricing model. Judge.me charges a flat 15 USD for its paid plan, while Yotpo, Okendo, Loox and Stamped scale with monthly orders, so cost grows with the store.
Free plan limits. Judge.me free has unlimited reviews and media; Loox free covers 500 orders; Yotpo and Okendo free stop at 50 orders a month.
Photo and video reviews. Loox is built around visual reviews; Judge.me includes media free; Yotpo adds it from Starter.
Google Shopping and syndication. Star ratings in Google need a syndication feed; check which plan unlocks it (Judge.me Awesome, Loox Convert, Yotpo Starter and Pro).
Billing predictability. Loox and Stamped reviewers report surprise charges tied to order counts; ask what counts as an order.
How we test product review apps
The test for this category: Import the same 200 reviews, request new ones from test orders; display, SEO markup and page-speed impact.
A test store with 20 products and test orders runs each app or service (payments in test mode, reviews imported from a sample set, upsells on checkout). Amazon tools are checked against real listings with known sales.
Each tool is tested on a paid plan, and its review shows the plan, the price and the test dates. The overall score is the average of the five parts on the right, rounded to the nearest half star. See the full method for ecommerce operations tools.

I've always been fascinated by the ideas behind successful online businesses. Pricing and features matter, but so do accessibility, customer experience, and the problem a platform is trying to solve.
