The description of the MMDD app iMiam is just marketing blather:
Here in digital format is the guide everyone's been using en route to Compostella.
Complementing all the printed trail guides that do a great job covering the history and geography of the route, MMDD has details essential to hikers: where to sleep, where to eat, at what cost?
Ranging 5 km to either side of the GR 65 from Le Puy to SJPP, it covers: religious welcome centers, hotels, hostels, B&Bs, camping areas, cafes, restaurants, post offices, bakeries, groceries, butchers, pharmacies, etc.
The prices and specifications are specified, so the pilgrim knows exactly where he'll put down his backpack, what his choice of accommodation might be, according to his beliefs, his tastes, and the thickness of his wallet.
Also designed to work for someone on horseback or with a donkey.
