I'm in the early stages of building a mobile app (starting with Android and then IOS). Upon opening the app I want user filters to be able to query real time into the remote database and load current state data. I want to use a SQL DB. I can't find anything for entirely free. And I'm not talking about very much data, maybe 500-1000 rows (~10 columns) across a couple tables. I do not have the knowledge or equipment to host my own server.
(Amazon RDS is only free for first 12 months)
