AltStore is an alternative app store for non-jailbroken iOS devices.
AltStore is an iOS application that allows you to sideload other apps (.ipa files) onto your iOS device with just your Apple ID. AltStore resigns apps with your personal development certificate and sends them to a desktop app, AltServer, which installs the resigned apps back to your device using iTunes WiFi sync. To prevent apps from expiring, AltStore will also periodically refresh your apps in the background when on the same WiFi as AltServer.
FEATURES - Resigns and installs any app with your Apple ID - Installs apps over WiFi using AltServer - Refreshes apps periodically in the background to prevent them from expiring (when on same WiFi as AltServer) - Handles app updates directly through AltStore
