For some reason my iPad apps never transferred.   What can I do without buying them all over again. It is still sncy and it is on photos

You won't have to repurchase any of your apps.  iTunes now allows you to re-download any previously purchased items at any time on any device.  However, any apps you had in the past should have synced over.  With iPad connected and iTunes open, be sure you have selected which apps to sync under the "Apps" pane at the top in iTunes.  



If the apps you are looking for are not listed then you'll need to re-download them from the app store.  (at no cost of course.)
