Good Afternoon @dixitarjun!
Thank you for your post! When updating your iPad you will want to ensure that iOS is updated to the most current version. This version should be 10.3.3 according to our Technology Team. When installing the app, you will want to ensure that the PS PowerTest app created by PowerSchool Group LLC is installed. There is an app called PowerTest 2017 created by CrowdCompass, Inc. which is unaffiliated with PowerSchool. If your iPad is updated to the above current version and the app crashes, you will want to uninstall the app and reinstall it, making sure that it is updated to the most recent version, which is version 1.19.10.
If you are able to see a small computer icon in the bottom left-hand corner of the app screen, it should be possible to contact Support by holding that icon down until a dialog box appears. You will then want to type 'help' plus the date backward (for example, since today is 3/06/18, the password would be 'help60'). If you are continuing to experience difficulty, Support would be happy to investigate further if you would like to send screenshots of the issue through a support case under the 'Contact Support' option at the top of the page!
