AltJIT allows apps sideloaded with AltStore to enable just-in-time compilation, more commonly known as JIT. JIT allows some apps to run significantly faster — or even at all — but iOS does not normally allow apps to use JIT for security reasons. AltJIT is an AltStore-specific workaround that allows you to enable JIT for any sideloaded app whenever you're on the same WiFi as AltServer.
- 1.Open the "My Apps" tab then long-press the app you want to use JIT.
- 2.Press "Enable JIT" to launch the app, and within a few seconds you should see an AltStore notification saying JIT has been enabled.
- 1.First, make sure that the app you want to use JIT with is running in the foreground of your device.
- 2.Go to “Enable JIT” > [Your Device], then choose an app you want to use with JIT.
