iOS 8.1 app crashes? Switch to Airplane mode.

Got problems - as a lot of us have - with iOS apps bombing at start up on 8.1?

Try switching on Airplane Mode. I've done that with a few of my favourite apps, such as Day One, and it works a treat.

Yes, it's crap that we should even have to consider doing this, but at least it lets us use our apps until Apple pull their finger out.
