Developer stopped updating models in 2014 and database is not comprehensive!!! – Nikon Camera Bible - The Ultimate DSLR & Lens Guide: specifications, reviews and more Review

If the app is to be of good use it needs to be updated as new models come out. The database for cameras is not the only one to be outdated; it doesn't even show the 35-70 f/2.8D lens released in the 90s. I would not recommend it.
