Ehm, sure but your ecosystem delivers also possibility to see all that map information even on smartwatch (for me it works on your free app on Samsung’s Gear S2 and latest Samsung Watch as well).
Other than that - the map layer is fantastic and is available offline. I don’t even count the situations when I am out of GSM coverage and any hint about terrain, forest roads, etc. were urgently needed 
You did a fantastic job with this app - Thank you!
The only downside is missing iOS port of Locus - but that’s another story as I don’t care much about Apple.
