We're using Firebase for analytics on our mobile apps. But Firebase only appears to report on active users for 1, 7 and 28-day rolling periods. These are not the industry standard reporting metrics I'm looking for.
We also have a web app, where we're counting unique active users in Google Analytics, and we'd like to be able to compare (and combine) MAUs from our apps in firebase with web MAUs calculated in GA.
Is this possible without BigQuery?
If no, how much will BigQuery cost us?
It seems crazy to have to purchase BigQuery for this purpose alone. Any help is appreciated.
