Bulletin App connected map for the social community

[WHC]

Good day!

I am making the app for the community connecting with map. 

App configures just link the bulletins, however the most difficult thing, it needs many bulletins as per address, city. etc., but 

Please advise me or let me know the bulletin service provider as possible as simple using app inventor 2. .

I am looking for firebase, but it is not easy to connect. 

FYI, i am making the log-in system using firebase. 

If you have any good idea for the bulletin app, please advise me.

I know my question is very silly, but your advice will make me expert :)

Google Fusion Tables has facilities for collecting posts by geographic location and mapping them.

If you just want to classify and select by geographical category, you

can define and grow your own hierarchy or larger and smaller groupings

(country/region/city/county/neighborhood) using List Pickers.

That would fit a tag based store like FireBase or CloudDB or TinyDB (for practice) better.
