You will have to do your own testing of the 3 GPS app and compare them to each other.

Read the reviews on Play Store about Magic Earth it has been around since 2015.

OSMAND+ can be used for car travel as an example along with biking and hiking.
It has builtin bike and hike paths that can be turn on and off.
You can also change how the map looks with different color layouts.
Also turn on and off how much details you want to see on the map screen.
These are just some of the things OSMAND+ has to offer.

As for IGO I have not used it so I can not comment on it.

Then report back and give us your evaluation of Magic Earth as you compare it to the other 2 GPS apps......
