AppLocker has not yet been updated for iOS 9 - though I am sure the developer is hard at work on an update.
There is another tweak that can "lock down" apps and such called "BioProtect." It HAS been updated to work on iOS 9. It is a paid tweak, so it's $2.99. But, from what I read about it (I don't need/use an app lock), it's supposed to work well.
So, you can either wait for AppLocker to get updated or get this other tweak. There may be other tweaks but these are the only I am familiar with.
Good luck with your decision.
