Volunteer Sign-Up and Shift Sheet for Community Events

Volunteer Sign-Up and Shift Sheet for Community Events is an offline app (one HTML file in a zip) for a community group, school parents committee, charity or society that needs helpers at events. Each event has shifts with a role, a start and end time and the number of volunteers needed. Volunteers sign up to shifts. The app refuses a sign-up when the shift is full or when the same volunteer already has another shift at the same time, so a full shift goes on a waiting list instead. After the event you mark who attended and who did not turn up, and each volunteer hours are added up.

The problem it removes: Volunteers sign up in a chat thread, some sign up twice for overlapping jobs, popular shifts overflow and others stay empty until the morning of the event. Nobody knows who actually came. This app shows every shift with places filled and places open, keeps a waiting list, and prints a sign-in sheet for the shift leader.

What is inside:

• Events with date, venue, organiser and a status
• Shifts with role, start and end time and places needed, showing filled, open and the waiting list
• Volunteers with phone, age group and a guardian for those under 18
• Sign-ups with a status: Confirmed, Waitlist, Cancelled, Attended, No show
• Checks that stop a sign-up to a full shift, a clash with another shift of the same volunteer, and attendance marked before the shift date
• Hours, attended shifts and no-shows for each volunteer
• Today page with open places, a waiting list and WhatsApp reminders for the next days
• A printable shift sign-in sheet and an event roster
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: community groups, parents committees, charities, residents societies and sports clubs that run events with helpers who give their time free.

What it is NOT: It does not record any payment, it does not check identity, training, police clearance or insurance, and it makes no statement about what the law requires for working with children. It only records a guardian name for volunteers under 18. It sends no messages: you press WhatsApp and send them yourself. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (157 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1909 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
