What to look for in a good event-day volunteer app

For a small charity, prioritize:

• Mobile signups
• Shift reminders
• Easy last-minute edits
• Volunteer contact list export
• Role/area assignment
• Check-in or attendance tracking

My practical recommendation

If you want the easiest path:

1. Use SignupGenius or VolunteerSignup.org for signups
2. Use Google Sheets as your master staffing list
3. Send reminders by email/text the day before and morning of the event

If you want, I can also give you a side-by-side comparison table or recommend the best option based on your exact event size and number of volunteers.
