I ran into the same problem -- no apps available for all the reference info. The typical websites were useless too as the pages are formatted for a 1,000+ pixel screen not a mobile phone.
So I've started reformatting/generating the data for a mobile ready site... no app to install.
It went live with a little bit of data just now:
www . EnginRef . com
I have a bunch of other stuff almost ready to go, but formatting stuff well for a ~300 pixel screen has been tougher than I thought. I've been putting the stuff I use the most up first, but if you have any requests hit me up at contact (at) enginref.com
