Perimetrr
Know who’s at work. Across one office or every branch. Staff sign in from their phones; managers see arrivals, lateness and hybrid schedules without dedicated attendance hardware.
Free for up to 5 staff. No payment card required.

What staff do
Lagos HQ Example workdayInside office Perimeter (example)
Her example arrival time is 08:50.
01 / SET UP
Add staff, set your office Perimeter and choose working days.
02 / CONNECT
Staff open your workspace and pair their browsers with their profiles.
03 / REVIEW
Staff sign in and out. On-site check-ins use location checks; managers review arrivals and exceptions.
Location accuracy depends on the device and browser permissions. Browser pairing is not proof of someone’s identity.
Less chasing attendance. More context for the people managing it.
Sign-ins use the office Perimeter—the workplace area you set. Phone location can be inaccurate, so review unusual records.
Staff connect once; administrators approve requests to switch devices. Keep browser-specific details in concise help where operationally necessary.
Sign-in attempts are saved on this browser and queued for verification when the connection returns. They count as attendance only after the server accepts them.
Choose office and home days with an easy drag-and-drop schedule, assign shifts, and review attendance against the schedule.
Export attendance records as CSV for review in a spreadsheet or your payroll process. Open the download in a spreadsheet or use it in your payroll workflow.
Watch Tower brings your company's branches into one view. Each branch keeps its own staff, schedule and records. Access remains restricted to people authorized for those branches.
