How do location aware dating apps store the locations of its

"Depends"

that's a very vague question you're asking

>>62174909
I just want any kind of answer, really. I'm trying to make a location aware app myself, and I have no idea what kind of options to look at.

>Any time user logs on check their location
>Update MostRecentLocation column on User row

basically there's going to be an sql database with the last known location for the users in it
if locations services are enabled it'll refresh every minute or so
if not it sticks with your last location

Depends what you define as "location-aware".
Do you mean 'find single girls in your city' or 'find single girls within 4 city blocks/in the same venue as you'.

look up "googlemaps api"

>Do they use some standard database
Yes, every company shares all their proprietary secrets about their dating apps and they all use DatingDB to share info with each other. Seriously what kind of fucking question is this.

>For the backend, we’ve used node.js, java, mongo, dynamo, redis, scala, SQS, kinesis, kafka, spark, kubernetes, rundeck and EMR to name a few.
