How wide should the fence be?
Wide enough for the site plus GPS error: phones are typically accurate to within 4.9 m (16 ft) under open sky, worse near buildings and trees, per GPS.gov. Set the radius in meters for each site and check it on the map.
GPS time clock with geofence · offline mode · no app to install
GEOTT, short for geo employee time tracker, is a GPS time clock for job-site crews. Every clock-in is checked against the site's geofence and screened for fake locations. Outside the circle? Refused, or let through with a flag: your call. No signal? The clock-in waits on the phone and syncs by itself.

Valid clock-in
77 m from the site center, inside the 150 m geofence. Hours start counting on Site 14.

What the foreman sees
Sample data. Pick where Luca is, drag the radius, cut the signal.
Because the clock-in carries its own proof. When a worker taps the button, GEOTT compares the phone's position with that job site's geofence and runs an anti-spoofing check against faked GPS. Inside the circle, the hours start on that site. Outside, the clock-in is refused, or accepted and flagged if you allow "clock in anyway".
| Situation | What GEOTT does | What you see |
|---|---|---|
| Inside the geofence | Valid clock-in; the hours count on that site | On site, with the time |
| Outside, "clock in anyway" off | The clock-in doesn't go through | Not clocked in yet |
| Outside, "clock in anyway" on | Recorded and flagged to the admin | Out of area, with a flag |
| No signal on site | Saved on the phone, synced automatically | The entry, after the sync |
Radius, anti-spoofing and "clock in anyway" in detail: geofence time tracking. Setup, from the first job site to the first clock-in: how it works.
Four things: how tight the geofence should be, what happens where there's no coverage, how a day split over three sites is recorded, and whether tracking the crew is legal. Short answers: sized to the site, stored on the phone, split at clock-out, and position only at clock-in and clock-out.
Wide enough for the site plus GPS error: phones are typically accurate to within 4.9 m (16 ft) under open sky, worse near buildings and trees, per GPS.gov. Set the radius in meters for each site and check it on the map.
Nothing changes for the crew. The clock-in is held on the phone and sent automatically once there's coverage again, so a basement or a rural site doesn't leave a gap in the hours.
Every clock-in belongs to a site. At clock-out, the worker splits the day's hours across the sites they worked on, so each job gets its share without a Friday rewrite.
Within limits that depend on the country and, in the US, on the state. GEOTT records the position when someone clocks in or out, not in between.
Because GEOTT is a web app. Each worker opens a link in the phone's browser and clocks in from there; nothing goes through an app store, so old phones with full memory aren't a problem. Workers who want it can add GEOTT to the home screen and get push notifications like any other app.

$7 per active worker per month. At the start of each month GEOTT counts who clocked in during the previous month and bills only those people. Admins cost nothing, there's no base fee, no per-site fee and no hardware to buy, and a month with no clock-ins costs $0.

Frequently asked questions
The one that holds up on a real job site. Look for a geofence per site, clock-ins that work with no signal, nothing to install on old phones, and a price that drops to $0 when nobody clocks in. GEOTT was built around those four: see how it works for construction crews.
It depends on where you operate: the limits change from country to country and, in the US, from state to state. GEOTT records a position only when a worker clocks in or out, never in between, and the worker sees the check on screen. Our guide to GPS tracking laws explains where the lines are.
Make every punch prove where it happened. A GEOTT clock-in must match the job site's geofence and pass an anti-spoofing check, out-of-area punches are refused or flagged, forgotten sessions can close on their own, and a missed punch counts only once you approve it. All the controls are on the features page.
Yes. With no signal, the clock-in is kept on the phone and uploads by itself when the network comes back, with nothing for the worker to redo. That covers basements, tunnels and rural jobs; the office sees the entry once the phone has synced. The offline clock-in page has the details.
Every page below takes one question from this home page and answers it in full: setup, features, the geofence, offline clock-ins, construction crews, the law on GPS tracking, the price and the team behind GEOTT. Start with the question your crew will ask first.
Open a free account: the guided setup takes about 2 minutes and creates your first job site. Set its geofence radius, send the link to one crew and watch the clock-ins arrive. The trial runs 15 days, needs no credit card, and nothing is charged automatically when it ends.
