OffDuty is the personal calendar app for shift workers. No company cooperation required — it works perfectly even if you're using it solo. Enter your shifts fast New monthly roster just dropped? With a few taps you can add the whole month into OffDuty, and it appears automatically in your iPhone Calendar. Recurring shifts? Set them up once — no need to type them in every day. Match free time with friends and family Create a group. Everyone's available time stacks up automatically — at a glance you can see when everyone is free. Spin up a hangout, add a location and a to-do list, and you're done with the "Wait, was that today?" group chat chaos. Does your company use Roster Architect? You can do even more If your workplace uses the Roster Architect scheduling system, you can connect with one tap. Your shifts are pushed automatically from the company side — no more manual entry. Request shift swaps, time off, or schedule changes directly from the app; once your manager approves, everything updates instantly. This is an optional feature — OffDuty works great even if you don't connect to a company. Features - Fast manual shift entry (default, anyone can use) - Automatic Roster Architect sync (optional) - Manage multiple separate groups for friends / family / coworkers - Shared checklists and event details - Shift swap and time-off requests (Roster Architect required) - Instant push notifications for all updates OffDuty Premium (optional subscription) Unlock unlimited groups, unlimited events, and advanced sync features. Monthly plan, cancel anytime. Privacy first Your shifts, groups, events, and checklists are stored only in your personal account. Nothing is sold to advertisers or shared with third parties. Even more important: even when you connect to your company's Roster Architect system, the private events you plan inside the app (hangouts with friends, family checklists, personal notes) are never synced back to the company or visible to your manager. The company side only sees what they already knew — your shifts and shift-swap requests. Your private time always belongs to you.
