ZOXS CHECK is a free utility and tools app developed by ZOXS GmbH for iPhone users. It allows users to easily check the technical details of their used iPhones or iPads before selling them on the ZOXS.de website. With the ZOXS CHECK app, users can independently perform a series of tests to examine the device's touchscreen function, speaker, camera, and battery performance. The entire testing process takes only 3-5 minutes, after which users receive a detailed overview of the test results.

To ensure a smooth testing experience, users should make sure their device is at least 30% charged, have a charging cable readily available, keep the SIM card inserted, and backup any sensitive data as the device will need to be reset in case of a sale.

By using the ZOXS CHECK app, users have more control over the evaluation of their device and can potentially give it a second life. Try it out and enjoy the convenience and peace of mind it offers.
