Show HN: HandsUp – Super Simple Volunteering

https://handsup.barryvan.com.au/
1•barryvan•1h ago
HandsUp is the straightforward and mobile-first volunteer-management platform that the communities I'm involved in needed.

---

Over the past year, I've been more and more involved in local clubs and activities. One of the biggest challenges I observed was with managing volunteers. People were trying to use WhatsApp polls, hand-written rosters, Google Forms, and more to organise events and manage volunteers.

A big part of the challenge was friction - not only for the volunteers, but also for the event creators.

After one particularly disastrous effort of trying to use a shared Google Sheet to build out a complex roster for a school fete, I decided enough was enough and that led to HandsUp. My goal was to reduce friction as much as possible, and to make it mobile-first for volunteers and organisers. It supports simple events as well as more complex rosters and slots.

Its first couple of trial runs have gone pretty well, so I figured it was probably the right time to share it with HN and get some more feedback! :) For organisers, signing up and logging in is via magic links in emails; for volunteers, there's no sign up required. Feel free to create events and try signing up yourself too.
