Distinct from eventdesk (full planning CRM) — this is the tactical day-of tool. Load a timeline, assign vendors per slot, broadcast updates to the crew, check-in guests. Your phone becomes mission control for the 6 hours that matter. For planners, MCs, venue managers, day-of coordinators.
Cocktails 5:00, ceremony 5:30, cocktail hour 6:00, dinner 7:00, first dance 8:15. Per-slot: who's running it, what vendor is involved, notes. Glanceable on phone.
Text all vendors when the timeline shifts (ceremony running 10 min late → delay dinner plating). Vendors acknowledge receipt. No phone-tag during crunch time.
Per-time-slot task list. Assigned to a crew member. Check-off as complete. Overdue alerts. You don't have to remember everything yourself.
Scan invite QR or look up name. Mark checked-in. Know when everyone's there to signal the ceremony start. Plus-one + dietary flags visible.
Quick-access contact info + payment status for every vendor. If the caterer is late, you have their cell in 2 taps.
Flask + session auth. Your client events + vendor networks stay yours.
Hosted plans are early-access. Self-host today; email tim@dangercorn.net to join the waitlist.
dayof is one of 220+ verticals scaffolded from the same template. Each gets a working skeleton for free; individual ones get promoted to full products as demand surfaces.
