Message in a bottle
Drop a bottle. Someone nearby answers.
Pin a short note to the map when you need a hand, lose something or want to warn your street. Neighbors nearby see it, reply and show up.

How it works
Three steps, all within walking distance
No groups to join and no feed to scroll. Just the map around you.
Drop a bottle
Need a hand, found someone's keys, or hosting a street picnic? Leave a note on the map for your neighborhood.
Someone nearby finds it
Neighbors within walking distance see your bottle. They can reply, offer to help, or simply show up.
Show up for each other
A reply turns into a knock on the door. When it's sorted, close the bottle so the map stays current.
On the map
Five kinds of bottles
Each kind has its own marker and icon, so you can tell at a glance what's nearby.

Privacy and safety
Your street, not your address
MiaB is built so neighbors can help each other without exposing anyone.
Your location stays yours
Neighbors never see where you are. Only the bottles you drop appear on the map, at the spot you choose.
Report and block
Every bottle, reply and conversation can be reported, and you can block anyone in a conversation.
Bottles fade out
Every bottle expires on its own, so the map shows what's happening now, not last month.
For adults
Accounts are for people 18 and over. We say what we collect, and why, in plain words.
