Find your next app in the data.
Clairo tracks every app in the Shopify App Store — demand, momentum and competition — so you can find the category with room to win, instead of guessing.
Most app ideas fail for the same reason: the market was already won, or the demand was never really there. The App Store shows you ratings and review counts — not which way the market is moving.
Clairo turns 22,000 listings into one question: where is there still room?
What Clairo shows you
Growing markets
See which categories are gaining reviews the fastest — real, measured demand instead of a hunch about what's hot.
Room to build
Find fragmented categories where no single app dominates. Low concentration is your opening to enter and win.
Beatable leaders
Spot incumbents sitting on big review counts but slipping ratings or stale updates — the ones you can actually displace.

From a market to a move.

How it works
Scan
Every app in the store, every day — ratings, reviews, pricing, launch and update dates.
Track changes
We store only what moves, building a history of review velocity — a proxy for how fast each app is actually being installed.
Surface openings
Categories ranked by demand, momentum and how open they are to a new app. The opportunity, on one screen.
Why review velocity?
Shopify doesn't publish install counts. But nearly every install can leave a review — so the rate a category gains reviews is the closest public signal of where merchants are actually spending.
Clairo scans daily and stores the deltas, not just the totals. That means you see momentum — which markets are accelerating and which are stalling — not a frozen snapshot that's already out of date.
