JetRise IT Solutions › App development › App Rescue & Modernization Sprint
Rescue and modernize your app in 1–2 weeks
Your app was rejected, stopped building in the latest Xcode, crashes on new iPhones or still uses old in-app purchase code. We fix it, bring it up to date and get it back on the App Store — for a fixed price agreed before we start.
