Roster-Calendar, developed by michael heinz, is a scheduling app for shift workers that maps irregular rosters onto a visual calendar. The tool lets users create custom shift patterns and add them with a single tap, while automatically calculating total hours and overtime and syncing with the native iPhone calendar. It targets nurses, emergency responders, and retail staff who need clear shift logs, quick roster entry, and verifiable time records for payroll reconciliation.

Scheduling speed makes rotation setup fast

The app's scheduling engine lets users create entire shift patterns in less than a minute, which suits teams that run complex rotations. It supports automatic recurring cycles so a multi-week roster can be applied across months without manual entry. For handoff or archival needs it exports schedules as PDF or CSV, enabling printable rosters and spreadsheet-based payroll checks. This reduces administrative setup time for rotating teams.

Backup and cross-device exchange protect roster continuity

The app includes secure backup and restore options with password protection, letting professionals preserve multi-year logs when changing devices. Cross-platform data exchange supports sharing between iOS and Android, which helps teams where members use different phone types. A companion Apple Watch app and widgets put today and tomorrow's shifts on the wrist for quick reference during busy shifts.

Calendar intelligence and layout aid multi-jurisdiction planning

Support for public holidays across 38 countries and color-coded templates assist long-range scheduling and compliance with local leave norms. The visual layout's clear color assignment helps scan multi-year rotations quickly, a trait frequently highlighted by shift-worker reviewers. Availability on iPad and an Android edition expands where rosters can be edited, keeping planning available on larger screens or alternate devices.

The app fits mobile-first shift workers, with trade-offs for enterprise needs

The app is a pragmatic option for individual contributors and small teams who need mobile roster management and clear shift records. Expect a tool focused on personal and team scheduling rather than full payroll or enterprise administration features. Larger organisations that require centralized role controls or audit trails should pair it with complementary systems; for mobile shift tracking, the app performs reliably.
