SignUpGenius is great for a one-off sign-up sheet, and its free tier is genuinely useful. But once you're running a real volunteer program, with recurring shifts, reminders, hours, and no-shows to chase, you outgrow it fast. Rally does the whole job, free, with automatic reminders that cut no-shows.
