Read every one-star review the day it lands.

App marketplace listings are the closest thing you have to a public support queue, and most teams only check them when someone remembers to. A one-star review mentioning a broken webhook can sit for three days before support sees it, and by then the merchant has already left a comment on your community forum too.

modsignal watches your listing, or a competitor's, on whatever schedule makes sense. Tell it what you care about: any new one- or two-star review, a rating drop below a threshold, a pricing tier that changed. It reads the listing the way a person would, not by scraping a fragile selector that breaks the next time Shopify redesigns the page, and it tells you what changed in plain language.

You get the review text and the rating movement in the alert, not just a link to go check yourself. That's the difference between finding out at your desk with time to respond, and finding out from an escalated support ticket. Start with the semantic tier here — reviews are unstructured text, and the exact-diff tier would fire on every new review regardless of whether it's a five-star or a one-star.

Reviews tend to arrive in bursts right after a release, which makes this one of the few use cases where checking every hour instead of once a day genuinely earns its keep. Point a second monitor at a competitor's listing and you'll see how their rating moves around the same releases as yours.
