On-call rotation that takes the fight out of it.

A seniority queue that runs itself, on the record, on every phone in your unit.

Everyone sees the queue. Everyone sees who's next. The rotation is the rule, not the rumor.

How it works

Six steps. Set up once. The app does the rest.

01

Director sets the queue.

Drag the staff list into the order your unit has agreed on. Holidays get their own rules in the same setup. The app enforces it from there.

02

A shift opens. Notification goes to everyone.

When a call shift posts, every eligible staff member gets the same push at the same moment. No one gets a head start.

03

Staff claims it, one tap.

First eligible person to tap accept gets it. Seniority order resolves any ties. Pass and it rolls down the queue.

04

Manager approves.

Every accepted shift waits on one tap from the manager. Approve, deny, or ask. Each action stamps the audit log with timestamp and actor.

05

Rotation moves to the next person.

The queue rebalances after every pick. Everyone sees who's next, anytime they look. No one moves up the line in private.

06

Every action lives in the history.

Picks, approvals, overrides, swaps. All recorded with timestamp and actor. Six months later, the answer is on the record.

Antonimar Mello, RN

Built by a nurse, on the floor

I built OnCallRank because the paper tracking never worked.

I'm an RN on Long Island. The rotation fight on my unit wouldn't end and management was taking the heat for what should have been a math problem.

I built the queue we wished we already had.

Audit

Every action. Every timestamp. Every rule.

Hospital legal and HR ask three questions. We answer all three before they ask. Every staff member sees the queue. Every action is on record. No one moves up the line in private.

1

Logged with timestamp and actor.

Pick, accept, pass, override, approve, swap. Nothing happens off-system.

2

No deletions, ever.

Append-only by Postgres design. A retroactive change leaves its own row in the log.

3

Visible to everyone.

Staff, managers, and directors see the same log. No private back-channel.

Security

Built for IT review.

Tenant isolation, by Postgres design.

Every unit's data lives behind row-level security. Cross-unit visibility is impossible at the database layer.

No PHI. Ever.

Shifts, schedules, queue positions. No patient information. BAA template ready on request.

Hardened hosting and full data export.

TLS, HSTS, append-only audit log. Your data is yours, exportable anytime.

Pilot

Three weeks. No cost. No commitment.

Pilot scope is yours: one unit, your staff, your seniority order.

01

Manager signs up and configures the unit.

Two minutes to create the account. Set seniority order, roles, and holiday rules. Send invite links to staff.

02

Staff joins.

Each invite link takes a minute. Once your roster is in, you're live.

03

Three weeks live.

Daily use. Audit log fills up. Real data.

04

Post-pilot decision.

Go or no-go. Full data export either way.

Honest

Who this is NOT for.

Closing the wrong-fit doors up front saves everyone a meeting.

×

Hospitals looking to replace their workforce backbone — time and attendance, payroll, accruals.

OnCallRank is the unit-level call scheduling layer. We sit next to your workforce platform, not inside it.

×

Units with no on-call coverage requirement.

This only matters when there's a queue to manage.

×

Health systems that require SOC 2 Type 2 certification for any vendor contract.

We're not certified yet. We're a fit for unit-level pilots and smaller hospitals while we build there.

×

Anyone looking for an AI-powered scheduling oracle.

OnCallRank uses no AI for the rotation. The director's seniority order is the rule. The app enforces it.

FAQ

Real questions we get.

Are you HIPAA compliant? +

OnCallRank doesn't store PHI. Shifts, queue positions, and manager actions only. We sign a BAA if your hospital requires one for any vendor regardless of PHI scope.

Does this replace our workforce platform? +

No. Time, attendance, payroll, and accruals stay in your existing workforce platform. OnCallRank handles unit-level call scheduling. We sit next to the platform, never inside it.

How do you handle override scenarios? +

Each round has a configurable time window — once a turn opens, the staff member has that window to claim or pass. If they don’t act, the manager can override and advance the queue. Every override is logged with timestamp and actor.

What happens to data if we cancel? +

You get a full export of every action ever taken on your unit. PDF and CSV. We delete our copy on your timeline.

Can multiple units in the same hospital each have their own rotation? +

Yes. Each unit is a separate tenant with its own queue, manager set, staff list, and rules. They share an organization but don't see each other's data.

Who's behind this, and what if you disappear? +

AF Mello Solutions Inc, an S-Corp registered in New York. Trademark and copyright registered. Your data is yours and exports cleanly into a spreadsheet your team can keep running with.

Can we see a demo before the pilot? +

Yes. Book the call and we walk through the manager and staff flows on a sandbox unit before any commitment.

Ready to end the fight?

Book the call. 15 minutes. The demo is the pitch.
