The request limit for the Airtable API is 5 requests per second per base (regardless of IP etc). If you cross that threshold, you’ll get a
429 response and need to wait 30 seconds before making your next call.
If that limit works for you, I think this is a great use case for Airtable!
As an alternative to querying the API / dealing with rate limits, quick plug: I built Sync Inc (https://syncinc.so/) for exactly this purpose. We setup a follower Postgres database for your Airtable that syncs in real-time. You could just connect the back-end of your Android app to that. Any ?s, let me know
