I don't know about the dev app, never used it, but standard tutorial is not "terrible". It is a far cry from sufficient, but most definitely not useless. It does teach how to swing a wrench, how to put out a fire, and the basics of piloting. The only problem with it is the lack of the more advanced things, like chem spray, or there is no reason to use range finder, because any gunner worth his powder can read that info himself.
