5. TidyHQ

Why it’s good:

  • Includes volunteer/member management and event coordination
  • Mobile-friendly
  • Useful if you want more than just signups

Free tier: Limited/free options may vary
Limitations: Not as lightweight as signup-focused tools; free features may be restricted


6. When I Work or similar shift apps

Best for: Shift-based staffing with reminders and confirmation
Why it’s good:

  • Built for schedules and shift coverage
  • Mobile apps for staff/volunteers
  • Good for assigning roles and tracking coverage

Free tier: Often limited or trial-based, depending on provider
Limitations: Many shift tools are not fully free for nonprofit use


Best picks by need

  • Simplest overall: SignupGenius
  • Most basic and free: VolunteerSignup.org
  • Most customizable at no cost: Google Forms + Sheets
  • Best if you want a database-like system: Airtable

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.
