App Store Optimization lives or dies on one feedback loop: install velocity raises search rank, higher rank raises impression share, and more impressions produce more installs. This 2D simulator makes that loop physically visible: a search-results funnel at the top divides 20,000 daily searches into an impression share by rank, and every day a burst of install particles is launched along a real projectile arc from the funnel down onto a live ranked bar chart of ten competing apps, landing and growing each app's install bar. Tune your listing's keyword relevance, star rating, conversion rate and paid user-acquisition spend and watch every app — not only yours — close its own velocity → rank → impressions → installs loop, with competitors drifting from their own fixed underlying persona plus daily noise.
