Not impressed... Could be great, but needs work
Just downloaded this app, and while at first glance it looks really amazing, it has some serious flaws. First, it frequently crashes on my iPhone 7 running 11. For iOS, just updated two days ago. But what is more troubling, is that while on his App Store page he advertises “fully searchable”, I have yet to see where in hell a workable solution actually exists to do that. The index says it searchable, but hydrography symbols, for instance, cannot be searched in a way that takes you directly to its definition. Hope this app get some attention soon, as it has incredible potential! But for now, I would not waste your money.
