...we should rise number of people in Locus team .. anybody interested in work? 
Yes, I would love to do the acquiring of new customers on Maldives and Bahamas, looking forward for long stays there to acquire many new customers on the beach sides

I tested a bit this Gaia app and beside a much too expensive (15 eu!!!) all average GPS app I found the IGN map for France included!
This is the only really interesting thing!
I remember when hiking in "mercantour", south France, 1.5 years ago, I needed these maps but couldn't get the download url so I copied all the jpg out from the website to use the map as pictures and this was important for our hike, the GR52A is marked on it. Other maps are more or less useless in this region.
How do they get it? Is that the reason their app so expensive, because they pay for maps like this one?
You can even download the IGN map for offline use in the app, I don't know up to which size, but there seems to be no restriction. I should scrutinize the requests with Wireshark

By the way, I didn't bought the app, I refunded in between 15 minutes...
