Early starts, nobody watching
The foreman can't stand at every site at first light. With a geofence around each job, a punch counts only from inside the circle, so the start time on record is a time someone was actually there.
Construction several jobs a day · dead zones · early starts
Crews start before the office opens, move between jobs and spend hours where phones lose coverage. GEOTT checks each punch against the site it claims, keeps it on the phone when there is no signal, and lets the crew split the day across the jobs they really worked.
$7 per active worker a month · 15 days free, no card · nothing to install on the crew's phones
Four blind spots the office can't cover from a desk: crews that start before anyone supervises the gate, jobs with no coverage underground or out of town, workers who touch two or three sites in one day, and hours written down on Friday from memory. A construction time clock app has to hold up against all four.

Basements, parking structures and rural lots often have no mobile coverage. The punch waits on the phone and uploads on its own once the device reaches a network again.
A pour in the morning, a punch list after lunch, a delivery at the third site. At clock-out the worker divides the day between those jobs.
GEOTT opens from a link in the browser, so a cracked phone with no free storage still works. The interface comes in English, Spanish, French, German and Italian.
Big enough for the whole work area plus GPS error. GPS.gov puts typical smartphone accuracy at 4.9 m (16 ft) under open sky and names buildings, indoor and underground use as common causes of worse readings. You set the radius in meters for each site, so a wide lot simply gets a wider circle.
| Type of job | Starting radius | Why |
|---|---|---|
| Single-family remodel | 50 m (about 165 ft) | Covers the lot, the driveway and the truck at the curb |
| Mid-rise build in town | 100 m (about 330 ft) | Walls and neighboring buildings pull readings off; leave margin |
| Large commercial or rural lot | 200 m (about 655 ft) | The circle has to reach the far corner where the crew parks |
| Road or utility work along a line | One site per stretch | A circle fits a long line badly; several smaller sites fit it better |
If a tight circle would stop honest work, switch on "clock in anyway": the punch from outside is saved with a flag for the admin rather than refused. More on the geofence time tracking page.
Yes. When the phone has no coverage, GEOTT stores the clock-in on the device and sends it by itself as soon as the network returns, so nobody taps twice. The office sees the entry after that sync: a crew that spends the morning in a basement shows up once the phones are back above ground.
On an iPhone the waiting entries go up the next time the worker opens GEOTT with signal, because iPhones don't let web apps upload in the background; nothing is lost, it can just arrive later. How storage and sync behave, step by step: offline clock-in.
Each punch starts on one site, and at clock-out every worker assigns the day's hours to the sites they actually worked. By Friday the by-project Excel export shows crew-hours per job, the figure you set against the estimate. The week below is made-up sample data for a crew of five on three jobs.
| Job site | Work | Crew-hours | Days without signal | Flagged punches |
|---|---|---|---|---|
| Site 3 | Retail fit-out, ground floor | 110 | 0 | 0 |
| Site 7 | House framing | 72.5 | 0 | 2 |
| Site 11 | Barn repair, rural | 30 | 2 | 0 |
| Week | Three jobs | 212.5 | 2 | 2 |
The two flags on Site 7 are "clock in anyway" punches from a truck parked across the street: you review two lines instead of arguing about a whole week. The 8.5 hours per day already have the break taken out by an hours rule. The full setup sequence is in how GEOTT works.
The foreman can run a job with project manager rights granted area by area: hours, documents, communications. Reminders ping only the people not yet on the clock, and recovered punches wait for approval. The office gets a monthly report of everyone by day, a weekly expected-versus-worked view and four Excel exports.
The by-project export is the one that tells you how many hours a job really took. Every tool for field crews is listed on the features page.
$7 per active worker per month. Early each month GEOTT counts who clocked in during the previous month and bills only them. Admins, office staff who never punch and idle months cost nothing, and there is no base fee or charge per job site. A 20-person company with everyone working pays $180.
| Month | Workers who clocked in | Bill |
|---|---|---|
| Busy month, every crew out | 20 | $180 |
| Slow winter month, two crews idle | 14 | $126 |
| Full shutdown | 0 | $0 |

It won't follow workers between punches: the position is read at clock-in and clock-out only. It needs no time clock in the site trailer, no badges and no app store. And it won't decide what's legal for your company, because the rules on GPS at work differ by country and, in the US, by state.
Before the first crew starts, read is GPS tracking of employees legal? and tell the crew what is recorded and when.
Construction questions
The one your crews keep using after week one. Check for a geofence per job, punches that survive a dead zone, hours split between jobs and nothing to install on old phones. Then test it with a single crew for two weeks; if they don't push back, move on to the next crew.
Make the punch prove its place. In GEOTT a clock-in has to fall inside the site's geofence and pass an anti-spoofing check against faked GPS. Punches from outside are blocked, or saved with a flag if you allow it, and a forgotten punch turns into hours only after a manager approves it.
GEOTT does for clocking in. In a basement, a tunnel or a field with no tower, the worker taps as usual and the punch stays on the phone with its original time. It uploads automatically when coverage comes back, and the office sees it from that moment on.
That depends on where the work happens: the limits change by country and, in the US, from one state to another. GEOTT keeps the scope narrow by reading the position only at clock-in and clock-out. Our guide on GPS tracking of employees covers what to check before you roll it out.
Pick the site with the worst coverage and one crew. Setup takes about 2 minutes: place the site, set its radius, send the link. Run it through the 15-day trial, which needs no credit card and doesn't bill itself when it ends, then compare the punches with what the foreman saw.
