How to build a mobile app for Lawyers Not Lawyering

Dear Indiehackers,

I run a community called "Lawyers Not Lawyering" which helps lawyers find meaningful work outside the law. Till date we have been successfully running the community on WhatsApp.

Off late we have realised that threaded conversations and ability to create micro-communities within the community will be of a lot of help. And we want to be mobile first (App Store + Play Store).

Therefore need to build an android + iPhone app. I am happy going drag and drop on this. Also would be really really helpful if someone wishes to help on this. In case you know some good resources for building apps or are willing to help do let me know.

P.S. I didn't go the "lets go and learn how to build android apps" route since my primary skill set is that of a community builder and not an app developer. Any help would be deeply appreciated.
