Creating a professional on-call roster is quick and requires no login.

1. Set your schedule window – Choose start and end dates.

2. Pick your rotation style – Daily or weekly rotations with 24×7 or business-day coverage.

3. List your team members – Add one name per line; the tool assigns shifts in a fair round-robin pattern.

4. Account for holidays and PTO – Exclude blackout dates and mark individual time-off periods.

5. Generate and export – Instantly view the formatted schedule, then export it as a CSV spreadsheet or an ICS calendar file.

The generated ICS file can be imported directly into Google Calendar, Microsoft Outlook, or Apple Calendar so every team member gets automatic updates.

• Fast and accurate – Build a full rotation in seconds with consistent assignments.

• Flexible – Supports primary/secondary roles, custom start/end dates, and time-off management.

• Shareable – Export to CSV or ICS to distribute schedules by email, Slack, or internal portals.

• Browser-based and free – No signup, no installation, no hidden fees.

• IT and DevOps – SREs, NOC engineers, and MSPs who need fair, trackable rotations.

• Healthcare providers – Hospitals and clinics managing physician or nursing on-call rosters.

• Utilities and field services – Electric, water, logistics, and emergency repair crews.

• Any 24×7 operation – From security companies to customer support groups.

Your on call calendar is only useful if it helps the right person respond when something goes wrong. OnPage turns static schedules into live routing rules, so critical alerts, notifications and messages automatically reach the correct on call engineer, technician, clinician, or responder the moment an incident occurs. These alerts could originate from anywhere: an OnPage user’s phone app, email, phone call, monitoring system, IoT, or any other system that can dispatch notification.

With OnPage, one can:

• Route alerts by on call schedule, role, and escalation path
• Automatically notify primary, then backups/secondary if no response
• Replace manual call trees, spreadsheets, and missed handoffs
