Whether a Divo, Chief, LPO, WCS, or even the fresh-out-of-bootcamp sailor, this app contains references and instructions that are essential for all. If you hate looking up naval instructions on policy, this is the app for you! When new instructions come out, this app updates and you have it available to you. As a Chief, this app has been a great reference tool when questions arise in my divisions.",

"title": "Had potential",
"body": "This app at its inception had great potential. At this current moment it still has just potential to be a great tool utilized by naval personnel but the failure of the development team to continue updating this app has likely led many Sailors astray. Major updates to policy and instructions have occurred and this team which I presume is paid well with a nice contract or the contract is over has failed to update it. In conclusion if you need any references just use the NPC website.",

You can now go F yourself is the business model the developers switched over to. This used to be, hands down, the best app to take quizzes on because it showed you immediately the correct answer if you got it wrong. F** it. Let ships collide.",
