A signup app for the team that comes back next week
Zelos keeps the roster, the chat and the history between events, so you're not rebuilding a sheet every time.
Signup sheets, time slots, and an email confirmation
Fits a one-off event and a link you share around.
Open shifts, task dispatch, notice board, and team chat
Built for a team that comes back.

How signup works in each app
A grid you share by link
You build a sheet of dates and time slots and send the link. People open it, add a name and email, and they're in.
Open shifts as the whole product
Admins post shifts and tasks; team members browse and claim what fits their skills and schedule.
What Wejoinin is better at
If your workflow depends on the things below, Wejoinin is the right pick.
Nothing to join
Participants open a link, type a name and an email, and they're signed up. No account, no password, no app. For a one-off event, that's the lowest friction possible and Zelos can't match it.
A sheet in under a minute
Add rows, add columns, rename a header, share. There's no project to configure, no roles to define, and nothing to learn. Zelos asks more of you upfront because it's holding more afterwards.
Office hours and appointment slots
Professors booking student slots, small businesses taking appointments, conference registrations. Zelos posts work for a team to claim; it isn't an appointment scheduler and doesn't try to be.
No roster to maintain
You never add anyone, remove anyone, or clean up accounts afterwards. The sheet is the whole system, and when the event is over there's nothing left to administer. Zelos holds a team, which is useful when you want one and overhead when you don't.
If these bullet points are non-negotiable, you're a Wejoinin user.
What Zelos is sharper at
If you coordinate the same people repeatedly, Zelos is a better fit.
Built for a team, not a sheet
Wejoinin starts blank every time; Zelos keeps the team. Members have profiles, skills, and task history, so the next shift goes to the right people without rebuilding the list from scratch.
Apps and push notifications
Zelos has native iOS and Android apps, and push notifications for new tasks, updates, and messages. Wejoinin runs in a browser and reaches people by email, which is where reminders go to die.
Chat that goes both ways
A signup sheet gives you no way to answer "can I swap Saturday?" without an email thread. Zelos gives each task its own chat channel, plus group chats and direct messages, so it happens in context.
Private by default
Anyone with a Wejoinin link can see the sheet and who signed up for what. Zelos workspaces are invite-only, members can't see each other's contact details, and it's built in Estonia under GDPR.
If you're drawn to this kind of simplicity, you should spin up a free project in Zelos right away.
mobile apps
Wejoinin runs in a browser and emails your volunteers.
Zelos ships iOS and Android apps with push.
What each one actually gives your team
The question isn't what either one costs, it's what each one gives you.

Teams that pick Zelos over Wejoinin
Volunteer-led nonprofits with ongoing programmes
A sheet works for the annual gala. It's heavier going when you post work every week and want to know who turned up last month. Zelos keeps volunteer profiles, skills, and task history between events, so you're not starting from a blank grid each time.
Learn more →Churches running weekly rotas
Sunday service, coffee, kids' ministry, and the food bank all repeat. A coordinator posts the week's slots once and the congregation claims what suits them, from their phones.
Learn more →Sports clubs and leagues
Match-day volunteers, kit runs, and canteen shifts across a whole season. Parents get push notifications rather than another email chain, and every section lead can be an admin at no cost.
Learn more →Youth programmes and student groups
Points and leaderboards are what actually move participation with younger volunteers, and a static sheet has nothing like them. Changemakers Academy took task completion from 20-30% of the group to 75-90%.
Learn more →Event staffing and on-demand crews
Paid crews and contractors need targeted dispatch and a chat channel per shift, not a public sheet anyone with the link can open.
Learn more →Disaster response and mutual aid
When a response scales to thousands in days, a shared grid stops working. Zelos handles smart targeting by skill and location, with chat attached to each task.
