Now ready for iOS 26, iiziRun Custom runs iiziApp's from an iiziServer without having to submit the app to App Store. Once you have completed your iiziApp development, you publish your iiziApp to App Store once in order to make it available publicly or for enterprise use using iiziGo Publish App, customized to your liking. iiziRun Custom supports integration with the device such as its camera, contacts, files, geolocation, speech and voice. The device integration is available using API's in the server for developers to use. iiziRun Custom is intended to perform testing of native device capabilities and functions that an emulator cannot provide or has limited capabilities of emulating. It also has settings to use a specific language so that you can use the same physical device to test the app for all target languages
