Every iOS developer hits the same wall after launch: the App Store rewards apps that already get installs, and ignores the ones that do not. So thousands of developers search "buy ios app installs" or "buy app store installs" hoping to jumpstart the algorithm. The problem is that most services selling installs deliver bot traffic - installs from device farms that Apple's fraud systems are specifically built to catch.
OnTopRank takes the same goal - fast, guaranteed iOS installs - and delivers it with real people. Every install on your app comes from a genuine developer with a real device and a real Apple ID, because they earn stars by testing your app the same way you earn stars by testing theirs.
