Hi Friends,
I have an app that needs to support several thousand daily users who will be checking in and out of shifts at a large site. Assuming a busy day I might get up to 20,000 hits on location per day
The checkIn/Out button will only be displayed when within 50 meters of a nominated entry point (which we know the lat and long of)
I’ve build a proof of concept with just the standard Bubble features and Google Geocode and Maps API keys. Logic would be simple and similar to this
What I don’t understand is how the Google API costs are chargedat such a scale
If I’m not displaying a map but just checking distance is that just a geocode call?
Does a second call only happen if the page is refreshed?
If I then display a map is that a geocode and a Map API call?
I’ve read the pricing here Platform Pricing & API Costs - Google Maps Platform but Im not sure which call it is thats made.
Advice appreciated including alternatives but I spent some time with the Mapbox plugin and couldn’t even get it to initialise 
so went back to keep it simple stupid.
Thanks in advance as always - Johnnyweb
