The AI-powered biometric time clock that knows if the job is making money.
Every punch verified by face scan, stamped with GPS, and costed to its job in real time.
Chronox tells you what's leaking — in dollars. One flat price, not a per-head bill.

Three seconds, gloves on — and it only works if it's actually him.
Three leaks in every contractor's payroll.
Your guy's in the truck; his buddy's at the clock. Nucleus Research pegs buddy punching at 2.2% of gross payroll. Call it $1,100 a year for every $25/hr man on your books. 16% of hourly workers admit they've done it. Other apps photograph it happening. Chronox refuses the punch: no match, no hours.
Paper cards, group texts, "pretty sure I was at the Miller job Tuesday." Someone burns hours every week reconstructing the schedule, doing overtime math by hand, and re-keying it all into payroll. Chronox turns that into a ten-minute review and a payroll-ready export.
Basements, steel shells, off-grid jobsites. Time apps that need coverage hand you blank days and guessed hours. Chronox will take the punch offline, face check included, and sync it when the truck gets back in range. In testing now, shipping with the iOS and Android apps.
Punch to payroll in four steps.
Crew punches with a face scan.
The foreman's phone or a site tablet is the clock. Your guys don't need an app, an account, a badge, or their gloves off — look at the camera, done. Chronox matches the face, stamps GPS, tags the jobsite, and refuses what doesn't match: no buddy punches, no photos held up to the camera. Crews spread across sites? Self-scan mode lets each man punch from his own phone, pinned to his own Face ID.
The foreman runs the day from one screen.
Who's on site, time entries, breaks, site delays, tools used, extra work: submitted from the field while it's happening, not scribbled down for later.
The office approves and exports.
Accounting reviews the week with rates already applied: overtime at 1.5×, double-time at 2×, per-man and subcontractor rates. Before anything's approved, Chronox sweeps the week for clock-vs-paperwork mismatches, missing entries, and pay outliers. Payroll exports in minutes, not a Friday.
Job costs move in real time.
Every approved hour hits its job and cost code: actual vs. estimate, percent complete, labor dollars burned. You find out a job is bleeding in week two — not at the final invoice.
Time apps tell you who showed up.
Chronox tells you if the job is making money.
Every face-verified punch already carries a job and a cost code, priced at that worker's real rate: overtime, double-time, and subcontractors included. So while other apps hand you a timesheet, Chronox is quietly building your job costs hour by hour, as the week happens. The timesheet and the job cost are the same record — nothing re-keyed, nothing reconciled.
Estimates vs. actuals, by cost code
Concrete, framing, electrical, or trade-specific panel terminations, slab rough-in, and trim-out — see which line is eating the budget while there's still time to do something about it.
Live burn and % complete
Hours and labor dollars against the estimate, updated with every approved punch. No last-minute surprises.
Extra work, captured and billable
Work outside the job's scope logged from the field with labor and materials, so change-order money stops walking off the job.
Crew and sub rates, costed right
You enter the real cost of specific pay scales and per-hour subcontractor rates, and Chronox computes the true cost and payroll in real time for you to see.
Most contractors learn they lost on a project when it's already too late to save their margin. Chronox moves that lesson to week two, while you can still fix the crew mix, bill the extra work, or stop the bleed. And when a job closes, Chronox scores the estimate against what it really took, cost code by cost code, so the next bid starts from your own actuals instead of gut feel.
Live dollars-vs-estimate like this normally means a $180–$370/mo tier or a full accounting integration. Here, $99.
Hours aren't the only thing walking off your jobs.
The same foreman screen that clocks the crew files the rest of the field's records: extra work tickets with materials and signatures, site delay logs built to limit liability, and which tools need to be billed to T&M customers — all submitted from the site while it's happening. No second app, no Friday reconstruction.
Out-of-scope work becomes a ticket, not a favor: technician hours, shop materials, and purchased materials on one record — signed by the customer and your manager before the invoice conversation. That's the kind of unbilled change-order money Chronox is built to catch.
Technician hours · Shop materials · Purchased materials · Two signatures
When the crew's behind and the GC wants to know why, you give them dated, signed, and GPS-stamped delay records with auto-logged weather conditions tied to the crew that stood idle — documentation you can take into a schedule claim, not a foreman's recollection from a truck cab.
Dated · Signed · GPS-stamped · Weather-logged
Each entry ties tools to a job, a day, and a location, so equipment stops vanishing between sites, and T&M customers receive the bill they deserve. When and where each tool was last used, on record.
By job · By day · By location
What's leaking, ranked in dollars.
Every day, Chronox reads every punch, rate, estimate, and job on your books and flags what moved the wrong way. Each badge in the notifications center shows you the big problems that actually move the needle.

INSIGHTSIf you're allergic to AI slop, good — we are too. The Chronox assistant isn't just another ChatGPT wrapper claiming to be "Specialized AI." It's powered by an entire ecosystem of computing that starts with a deterministic engine computing every value in your organization. Then top AI models — trained and programmed specifically for Chronox and the construction industry — summarize that data, show you where to improve the business, and execute any task for you in the app, one time or on a repeated schedule.
You select your favorite model, then put it to work in plain English: "Every Friday, sweep the week for unbilled extra work." It runs, it reports, and it never touches money or payroll on its own: Chronox prepares, you approve.

The certified stack behind Chronox Face ID — matching evaluated in NIST's FRVT program, liveness conformant to ISO/IEC 30107-3, biometrics encrypted on SOC 2 / ISO 27001-audited AWS infrastructure
Every claim above is checkable: pricing and docs cited at the bottom of this page
And the fundamentals, done right.
Consent built in
Workers e-sign a biometric consent before their first scan. Templates are encrypted math, never photos. When someone leaves, the template is destroyed and a deletion receipt goes on file. Never sold.
Tracks the clock, not the person
GPS is stamped at the punch. No breadcrumb trail between punches, no after-hours tracking, no batteries dead by lunch.
Breaks that hold up
Meal and rest breaks to the exact minute, flagged short, missed, or late against your state's rules — records that end wage disputes before they start.
Works in dead zonesIn Testing
Punches will record offline, run the face check on the device, and sync when signal returns. In testing now, shipping with the mobile apps.
A certified face-ID stack
The matching behind every punch is evaluated in NIST's FRVT program, the liveness check is iBeta-tested to ISO/IEC 30107-3, and templates live encrypted on SOC 2 / ISO 27001-audited AWS infrastructure.
Payroll-ready exports
Approved hours to a payroll file in one click, OT and DT weighted, shaped for the system you already run: Gusto, QuickBooks, ADP, Paychex, Square, OnPay, and 5 more.
A view for every role
Foreman, accounting, management, admin — each gets its own view and a built-in walkthrough.
Full audit trail
Every change, who made it, and when.
Your data, exportable
Every punch, job, rate, and payroll line — plain CSV, any day you want it.
Per-seat pricing punishes you for hiring.
To get time tracking plus job costing for a 20-man crew, here's what the field actually charges (as of July 2026):
No base fee. No admin license. No annual prepay. No implementation fee. No per-seat anything — hire man #21 through #30 and the price doesn't move.
Against any competitor on that list, the lifetime license pays for itself in under a year. Every month after is free.
Three ways in. One flat price.
Every plan covers your whole crew. None of them charges per seat.

From the founder
I'm Karson — an apprentice electrician with IBEW Local 725 and the founder of Chronox. I built it to be different from the sea of other software aimed at contractors. But first, what it actually does — the part most of them make you dig for.
Chronox is a time clock that knows whether the job is making money. It verifies who clocked in with an on-device face scan that works even with no signal — so a punch on a dead-zone jobsite still proves the right person was there, not a buddy covering for them. Every hour flows into live job costing — labor against your estimate, in real dollars, while the job's still moving. And it captures your extra work and change orders in the field — your highest-margin hours — before they're remembered wrong and never billed.
That's the core: face-verified punches, foreman approvals, clean payroll export to the tools you already run, and an AI that answers questions about your own labor and never makes up a number. It's live today, with contractors already running real payroll through it.
We don't charge per hire or by your revenue. I've seen the frustration of being charged more as you grow, and the last thing you want is to be punished for it. So Chronox is flat — $99 a month for up to 30 workers, every feature included. The 30-man crew that runs about $320 a month on a per-seat tool costs the same $99 here.
I also believe in business that gives equal value to both sides. Buy annually and you get 2 months free — $990 for the year instead of $1,188. You trust you'll use it for a year; in return, we give you real savings.
We want recurring revenue, not customers who leave a week later — we can't succeed unless you stay. So we build what our customers actually want. Most apps are run by support teams that can't make real changes; with a small startup, you ask for changes and we implement them. As one of the first through the door, you help decide what gets built next.
That's where our founding licenses come in. Chronox is bootstrapped entirely by me, an IBEW apprentice. To make it in software, my only choice is to do something different than quietly charging $99 a month and hoping to save up the capital it takes to reach the contractors who need this — so we offer founding licenses. Not to line our pockets, but to give Chronox the boost it needs to earn a real customer base.
Here's what one is. For $1,995, one time, you own Chronox for life — every feature, up to 30 workers, and every improvement we ship, with each worker past 30 just $6 a month. No renewals, no per-seat creep, no price hikes, ever. At $99 a month it pays for itself in about twenty months — then it's free, for good.
If you're ready to deal with a company that actually values its customers and be a part of a real change, claim one of the 25 here: app.chronoxapp.net/signup. Not ready to commit for life? Lock a founding rate of $495 a year for as long as you stay.

The questions a contractor actually asks.
What happens to my crew's biometric data?+
Before anyone's first scan, they e-sign a biometric consent right in the app: built in, not paperwork we leave to you. What's stored is an encrypted mathematical template, not photos; it can't be turned back into a face, it's used for exactly one thing — verifying that the person punching is the person on payroll — and it's deleted automatically when you remove a worker, with a deletion receipt on file. Never sold, never shared. Chronox is designed to support state biometric laws like Illinois BIPA, with the consent and retention pieces already wired in. Full details in the privacy policy. The stack doing the work carries the credentials: NIST FRVT-evaluated matching, ISO/IEC 30107-3 liveness detection (iBeta-tested), and SOC 2 / ISO 27001-audited AWS infrastructure underneath.
What if the jobsite has no signal?In Testing+
That's what the iOS and Android apps ship with: punch anyway, the face check runs on the device, and the scan, time, and GPS sync once you're back in coverage. The apps are in testing now. Until they land, the clock runs in the browser and needs a connection — and a foreman can always key a missed punch in seconds, flagged for office review.
Do all my guys need to download the app?+
No. The foreman's phone or a site tablet works as the clock; the crew just looks at the camera. No apps to install, no passwords to forget, no badges to leave in the truck. And if you'd rather crews punch from their own phones, self-scan mode does that too — each scan pinned to that worker's own Face ID, so nobody clocks in a buddy from the parking lot.
What exactly does "lifetime" cover — and what if I grow?+
One company, all features, all future updates, and support, for as long as Chronox exists — up to 30 active field workers. Past 30 it's $6 per additional worker per month. You're never forced onto a different plan, and a growing crew never gets locked out of the clock.
Is the Chronox assistant just a normal chat bot?+
No — and that's by design. Every dollar figure comes from a deterministic engine doing analysis on your own punches, rates, and estimates, and each figure must trace to a defined metric before it reaches your screen. Furthermore, this assistant can be put to work to complete any task in the app, either one time or on a recurring schedule. Say "Add a field worker account for John Smith," and Chronox asks for any clarifying details and creates the account.
What if Chronox goes out of business?+
Fair question to ask about a young product, so here's the honest answer: We can't promise Chronox is available forever. But I can promise you're never trapped in it. Your full history — every punch, job, rate, and payroll record — exports to plain CSV any day you want it. And if Chronox ever winds down, you get advance notice and a final complete export before anything goes dark. That's a written commitment in the terms.
How is this different from QuickBooks Time, busybusy, ClockShark…?+
Most of them just record time. Chronox tells you if the job's making money. One — identity, not a photo: QuickBooks Time, busybusy and ClockShark snap a selfie a manager eyeballs later; nobody matches it to the man. Chronox matches the face with a liveness check at the punch — no match, no hours. Two — job costing that's already on: no higher tier, no QuickBooks sync, every punch on its cost code and estimate live. Three — extra work and change orders, plus equipment and tools, that go unbilled: Chronox logs them with detailed records ready for invoice. None of those three do — that's your margin walking off. Four — a real assistant: ask it which job's over or if payroll's clear, and it answers off your own numbers, never a made-up one. It runs your weekly report, drafts daily logs, and executes real tasks only when you say so. Five — one flat $99 for the whole crew, while theirs climbs every time you hire.
How fast can we actually start?+
Same day. Add your jobs and your crew, and the first punch works. Each role gets a built-in walkthrough on first login. Your next payroll period can close out of Chronox.
25 licenses at this price. Then it goes up for good.
$1,995 once, $495 for your founding year, or $99 a month flat. Verified time clock, job costing, an agentic AI assistant, and much more — on every plan.
