Shopify Apps
Every app you add to a Shopify store ships JavaScript that runs on your shopper’s device, and most vendors will show you a rating but never a blocking time. So I measure it myself, then put it next to the real monthly price. These are my app comparisons and buying guides across reviews, email, chat, popups, subscriptions, loyalty, search, tracking, and more, each one decided on the two numbers that actually matter.
