Ratings and Reviews

My new goto app


I am glad this app gets timely updates. As an FSO, having the regs this handy takes hours off research time and keeps them within reach without the bulk of the big books. The updates are icing on the cake. Have already gotten my money's worth out of this and the State statutes app. Keep it coming!

Very helpful


I use this app everyday for my job and it's updated often so I always have the most up to date regs where ever I go with out the bulk of carrying the actual books around

Super handy


Very useful way to navigate and search CFRs. I use it daily and have yet to be disappointed. I like the part numbers listed near the table of contents. Super product.
