How HROTG
puts HR
in every
employee's pocket.

HROTG is an HR, time-attendance and payroll platform. Its employees clock in, apply for leave, swap shifts and collect their payslips from one app, in three languages — and their supervisors approve from the same place.

This is the app behind it.

THE OPERATING REALITY

Most of the workforce
is not at a desk.

Shift workers, site staff and supervisors spend the day on their feet. An HR system they can only reach from an office computer means paper forms, phone calls and approvals that wait until someone is back at a screen. The phone is the only HR terminal they carry.

HROTG needed an employee app that covers the whole working month — clocking, timesheets, leave, shifts, approvals and pay — in the languages its users read, and that keeps passing App Store and Google Play review as both platforms change underneath it.

THE SOLUTION

HROTG's employees run on
an app we build
and maintain.

One Flutter codebase, released to both stores, connected to HROTG's platform. Each screen is a part of the working month an employee used to handle on paper or by phone.

01

Clocking with location

Employees clock in and out from their phone, and each punch records where it was made — so attendance matches the work site.

02

Timesheets, team by team

Daily timesheets and summaries for the employee, for the assistants working alongside them, and for a supervisor’s whole team — with remarks and review.

03

Leave and balances

Apply for leave, follow it through approval, and see annual-leave, overtime and rest-day balances without asking HR.

04

Shifts that flex

Bid for open shifts, swap a work or rest shift with a colleague, and declare availability — each one a request that goes to the right approver.

05

Approvals on the move

Supervisors clear leave, late-timesheet and shift requests from a to-do list, prompted by push notifications, with a full approval history.

06

Payslips and tax forms

The monthly payslip and the annual IRD tax-return form, as PDFs the employee can open, save or share from the app.

We sit between HROTG's platform and the people it pays — so the employer runs HR in one place, and every employee carries their part of it.

RESULTS

What working with HROTG has
taught us to build for.

What the app makes possible:

01

HR answers itself.

Balances, schedules and payslips are on the phone, so the routine questions stop arriving at the HR desk.

02

Approvals don’t wait for a desk.

A request reaches the supervisor as a notification and is cleared from the to-do list — wherever the supervisor is.

03

Attendance that holds up.

Every clock-in carries its location, giving payroll a record it can stand behind.

04

One app, many employers.

Each employer’s staff see their own brand, without a separate build per client.

Detailed metrics available on request under NDA.

A working relationship since 2022

A partnership built on
the app still working next year.

Shipping a mobile app is the start. Every year Apple and Google move the ground — new OS versions, new SDK targets, stricter rules on location and file access — and an app nobody maintains is removed from the store.

We have carried the HROTG app through those changes since 2022: framework upgrades, store-mandated SDK targets, permission clean-ups, and the features HROTG's employers ask for along the way.

The employee never sees any of it. They open the app, and it works.

Touchpoint

An ongoing build-and-maintain relationship with an HR and payroll platform.

Scope

The employee app on iOS and Android — design, build, store releases and upgrades.

Posture

Platform-led delivery — HROTG and its employers set the roadmap; we keep it shipping.

FROM PUNCH TO PAYSLIP

One path,
from the first clock-in to the payslip.

An employee clocks in on site, logs the day's work, and asks for leave or a shift swap. The supervisor gets a notification and approves from the to-do list. At month end the payslip arrives in the same app — and at year end, the tax form.

That's the shape of the work: time, approvals and pay as one loop in one app, not three systems and a paper form.

Clocks in, logs work, requests leave or a swap.

Supervisor

Wherever they are

Notified, approves from the to-do list.

Payroll
