I'm CTO over at https://skatespot.com -- we're about 3.5 years into development. Our app is finally live (we pivoted from pwa to native mobile apps using expo/react because maps weren't very accurate in browsers). It's been slow but now we are focusing on growth.
Could you expand on that? That sounds like an odd reason to pivot to native. Isn't accuracy determined by the data and or the projection system you're using?
so doing a pwa we used openmaps and the gps was not very accurate for slow moving objects, (ie: skateboarding). THe native apps using google maps (android) or apple maps (ios) were more accurate at slower speeds.
