Just talk, and the apps your group or friends needs appear in the chat. "We're 4 friends training for a marathon, build us a tracker" becomes a real app: leaderboard, streaks, a $500 pot, and the AI poking whoever skips a run. Shared software, generated on the fly: native iOS UI, one live state for the whole chat, zero setup. Full-blown social apps, not widgets. We're starting with fitness. A real messenger. Free.
