The people, and where they are
Profiles and a nearby view, so a community that already exists on the ground has somewhere to exist on a phone. Not a feed of strangers: the people within a few kilometres of you.
A marketplace you can post to
Anyone can list, not just registered shops. Browse, search, add to a cart and arrange it between yourselves. The things a household actually buys for a festival are sold by neighbours, not by a warehouse.
Services, and who performs them
The purohit, the cook, the decorator, the tent house. Listed with what they do and reachable directly, instead of a number passed around a family group until it is out of date.
Chat is not a tab. It runs underneath everything.
A marketplace between neighbours is a conversation, not a checkout. So every listing, every service and every profile opens into the same chat rather than a contact form.
It is built to be used the way people here actually type: Hindi in Roman script, Bengali in Bengali, English in between, often inside one sentence.
Built in React Native, so one codebase covers the phones the community actually owns.
