Group hangout planner
Planet4.Us
Planet4.Us is for getting a group from “we should do something” to an actual plan. Everyone weighs in the way they would in a group chat, and the plan takes shape while the conversation is still going. When the group is ready, one tap locks it in.

What it does
One link, no accounts
Start a hangout and share one invite link. Friends land straight in the chat, with no sign-up and nothing to install.
Vote right in the chat
Drop a poll for the date, the time, the food spot, the activity, or the vibe into the conversation, and everyone votes where they’re already talking.
Real places on a map
Search for restaurants and things to do, see photos, opening hours, and a map, and add the best ones to the vote.
Nova drafts the plan
Nova reads the chat and keeps a draft itinerary up to date while you talk. Say “Nova” when you want it to chime in.
People make the call
Nova only suggests. The organizer reviews the draft, everyone marks themselves ready, and one tap locks the plan for the whole group.
Stay in the loop
Get notifications on your phone, or a daily email you can vote from without opening the app. Add friends to invite them with one tap next time.
