Repeater data can be downloaded and viewed offline/airplane mode but theres no intuitive way to browse though them and the map will not work. Lots of features break unless youre online.
If youre truly off the grid then you need this to work properly offline. For the same price you can get a hard copy of the repeater directory which does work offline very well.
Cant save favorties either.
