CoMaps works really well as a wrapper of OpenStreetMaps. It even has seemingly-accurate hours for a few businesses near me! And if you are willing to dig into accessibility settings on the iPhone you can choose a good quality voice for navigation.

But yeah it’s offline navigation with all of the limitations that come with that

I never noticed that with google myself. I will say between apple maps and google maps that google maps is far more accurate for traffic estimates. You may be tempted to go with apple maps sitting them side by side when apple says its 6 mins faster than google. That is not apple maps finding some magic route. That is apple maps being dumb.
