i first considered this when maps.me went to shreds. for a while, i used both organic maps and osmand for my cycling trips. the cleaner interface of organic maps won me over. my main gripe at that time was the absence of a route import function. the dev team added that recently. now, i can import both kml and gpx formats.
now, if there is a way to save the in-app planned routes, that would be a huge help.
last i used it, it became a slow, resource-hogging, ad-riddled, bloated mess.
