I've used plenty of apps on my phone while it was charging for well over a year now and I've had no issues. The only thing which will be different is that the phone will charge more slowly, because you are doing things on the phone which require power too. If you want to quickly charge your phone, it is best to completely shut it down and then plug it into the charger. However, if you want to use the phone while it's plugged in, there will be no issues.
