> Which one is better?

The answer there likely dives too much into personal preferences to be a "one size fits all" answer.

Both are available on f-droid, so just try both and pick the one you prefer:

Osmand: https://f-droid.org/en/packages/net.osmand.plus/

Organic Maps: https://f-droid.org/en/packages/app.organicmaps/

Osmand is free, in app purchases are for larger offline download map size and other things, IIRC.

I’d summarise it like this: * Organic Maps: simpler, nicer, more intuitive UI. Better for most general use cases. * OsmAnd: a somewhat clunky UI, but more powerful and flexible. Better for advanced use cases.

Organic Maps is a better starting point IMHO.
