Which app do UK users recommend for tracking your location and what's around you whilst walking?

I'll shortly be moving to a new town, and was hoping that people would be able to recommend a good app that will help me get around and familiarise myself with the local area.

My typical use case is likely to be simply out exploring the area on recreational walks, so not navigating to a specific location. Ideally the app will announce my current location; what's around me whilst I walk; and approaching junctions.

There are many apps which appear to fit the bill, but are there any which are better than others for the UK?

Thanks for sharing any recommendations ☺️
