JP Constructions
— Employee Attendance Tracking App

Knowing exactly who is on site, and when, is deceptively hard for a business working across many locations. JP Constructions wanted to replace paper timesheets and guesswork with something accurate and live. Krify built an employee attendance tracking app that lets field staff check in and out from their phones, verifies their location with GPS, and gives managers a real-time view of hours and attendance across every project. It runs on Android, iOS and the web.

The Challenge

For a construction business with teams spread across several sites, attendance was a daily headache. Paper records were slow and error-prone, and managers had little visibility into who was actually working where. The problems were clear:

Scattered site attendance: Difficult to track workers across multiple project locations.

Manual record errors: Paper timesheets and spreadsheets caused mistakes and payroll delays.

False check-ins: No reliable way to verify workers were actually on site.

Limited real-time visibility: Managers lacked instant visibility into worker locations and attendance.

Scalability challenges: The existing process could not efficiently support a growing workforce.

Our Solution

Krify built a mobile-first attendance system that pairs quick digital check-ins with location verification, so every record is both effortless and trustworthy:

Check in from a phone

Digital check-in and check-out replaces paper timesheets completely.

One live view

A central dashboard shows attendance and hours across every project in real time.

Verify with geofencing

Site perimeters mean check-ins only count within the right project boundary, stopping off-site clock-ins before they happen.

Prove it with GPS

Location verification confirms staff are actually on site the moment they clock in.

Less admin, more accuracy

Automated records cut manual work and remove reconciliation errors.

Payroll-ready in a click

Accurate hours flow straight into exportable reports, so timesheets no longer need to be rebuilt by hand at the end of each week.
