Best off-line navigator for Android 2015

It's December 2014 and I need to go back for Christmas to Italy from France, so I need an “off-line” navigator for my Android smartphone, that is one where, contrary to the default Google maps, I can pre-save the map on the sd card and use it without internet. And possibly, I want it free.

So I tested 7 of the most popular gps android applications that offer off-line turn-by-turn navigation.

I can with confidence affirm that today the “winners” are 2:

By far the simpler interface, faster to render the map and to compute the trip, even a long one. It is completelly free, and I like that before starting the navigation it allows to see and choose between various possible variants.

It is the most comlete, options rich and map detailed solution. However you pay this richness in a interface that it's way more complicated than HERE and in a general slowness. To compute a trip between Nancy to Turin (420 km involving 3 countries) it tooks (remember we are using them in full offline mode) 5 minutes, agains the few second of HERE. Also,if you want to download more than 10 regional maps, you pay a one-time fee of 8 US$ (very small compared with e.g. the ~40 USD per single area of Sygic). As a plus both the app and the maps (OpenStreetMap) are open source, and you can use the app to contribute back to the main database. Also, differently from HERE, you can choose to download a “complete” regional map or a much more compact roads-only“ map.

You want a simple solution tha it works well ? Go with HERE maps. You prefer to have more control, settings and prefer an open-sourse solution? Go for OsmAnd.

Both are on the Play Store, and given their quality I am sorry I don't see space for the other solutions that I tried: Sygic, NavFree, Be-on-road Navigator, MapFactor Navigator.
