This map is pretty good, loads fast, and is easy to use. I like the layout of it better than other ER maps out there. So much so that I paid to unlock the entire app. One change is that I wish some of the item listings had a bit more information. Also, if I click them from the map, the app would take me to their info page that I know exists already. One issue is that if I do not use the app for a while and go to launch it, it immediately crashes. Though it will open up fine right after that.

Overall it's a great app, but I've run into a number of issues while using it. The most annoying is that poise isn't being properly calculated in the build planner. I'm not sure what the exact issue is, but using the Mausoleum Knight set shows 37 poise in the app, when it's 45 in game. I've seen this while a number of other sets as well.

Offline map is useful. Checklists are useful, though they could use a little refinement. The user interface is kind of lacking, considering it's a long list of things. Would be better if it had a tile layout, instead of a long list, and had images from in-game. It lags a little bit, and some taps don't register, but that's a minor issue. As it is, it's average. Neither great nor bad. The fact that it's offline capable is a bonus, and will make it more useful than other apps of a similar kind.
