The Locus Pro app I use gives you the option to use voice turn by turn. The U.I. on the app is very much over the top so not the easiest app to operate. There is a setting in the Locus app that allows you to set the app to prompt you if you go off route. I think I have mine set for something like 150 ft. After that it gives me a beep. At that point I have to stop to check the map to see what I've done. Can't remember right off hand if it will re-route if on the road but likely it gives you the option. I've just never needed or wanted to use a function like that.


I use the RWGPS website to plan my routes. While I can't download directly to my Locus app anymore I can download to my Dropbox acct. From there I can access any downloaded route directly to my Locus app. Locus lets me use a number of maps that are incorp. within the app. I generally use Open Map Cycle as that map will include some off road trails as well as MUP. Locus like some of the others also allows you to purchase some maps for off line use.


The Komoot app looks very promising. I may have to try that myself as apparently it too allows you down load maps for off line use, a big plus.

Last but not least is the Cuesheet app. The one big plus about Cuesheet is that ( AFAIK ) it stills allows me to access all the routes I've saved right from the RWGPS website. The U.I. is rather simple too making it easy to work with. Been a number of years since I've use my Cuesheet app though so I'm sure there must be updates that might change some of that stuff. Not sure if Cuesheet gives prompts if off route but it might. Worth looking into if you want something that ( used to be ) more simple to work with.
