Built for any group in motion
Whether you're coordinating a household, a roommate group, a sports team, or a crew of collaborators — SPARO holds the shared plan so everyone can just show up.
Kids, sitters, partners — everyone on the same page.
Shared chores, bills, and who's home when.
Practices, games, carpools, and gear.
Anyone coordinating recurring plans together.
What SPARO does
Every member, sitter, practice, and appointment in a single view — with categories, colors, and layers you can toggle.
Wake up to a short brief of the day: who's going where, what to prep, and what's likely to slip.
SPARO spots overlapping trips and suggests carpools and clean handoffs between drivers.
Packing lists, gear checks, and prep items live with the event — so nothing gets forgotten at the door.
Reminders that know travel time, weather, and who actually needs the ping.
Your group's calendar is yours. Granular sharing, no ads, no data sold.
Most calendars store events. SPARO moves the whole group.
Traditional calendars are stacks of solo agendas pretending to sync. SPARO is built from the group up — so plans, people, and prep travel together.
SPARO's atom is the shared plan — not one person's inbox. Everyone sees the same picture, in the same place, in real time.
Drivers, prep lists, reminders, weather, travel time — all attached to the event, not scattered across chats and sticky notes.
Daily briefings, conflict spotting, carpool suggestions, and follow-ups happen automatically — so nobody has to be the family router.

The name
SPARO is named for a murmuration — the swirling flock of small birds where no single one leads, yet they turn as one. That's the idea behind the product: a group in motion, moving together.
