I spent a few hours last night trying to make the IGN map system work. It provides instructions of a sort, that is, definitions of the functions of the app. These are available in English, and the app chooses the language to use according to the language of the device. But the English is obviously a very primitive machine translation. At best, I found myself putting the words back into Spanish and trying to understand what the instructions might mean in context. At worst, it is simply gibberish in English. And there is not enough basic instruction for those of us who are not really competent in using apps. I suspect that, like most other people who design apps, they design for one another (and for that tec savy 5 year old that we oldies here refers our challenges to) and don't really consider the needs of the many people who would like to be able to use the app, if we knew how. Or could figure out how. In my own city, residents are currently trying to figure out how to adjust to the changes in a public parking app: nobody wants to pay a fine because the app now has a different way to set up a warning message when the parking which has been paid for runs out.
I definitely shouldn't be addressing my rant to you, since you have been kind enough to offer to help. I don't know how you could help, however, as we don't speak the same language. I just go on struggling. I don't understand how to do basic things with the IGN app. And I just go on trying to do things, usually unsuccessfully, and occasionally something I do works, but I don't know what I did. I must say, maps.me is much easier to use. The simple directions of the Dutch pilgrim group made it possible for me to add the camino routes to the maps, and that has proven very useful. Both apps share the weakness that update are always going to be late. Word of mouth, passed on through this forum, is still how we tell one another that albergues have closed, a route been moved, or new services or accommodations are available.
I will go on trying, learning what I can and using what I learn. The camino has expanded my horizons in unexpected ways. And thanks to all those who try to assist we tec illiterate.
