Compliance lives in a spreadsheet.
Audits know it.

It starts innocently, one workbook, one careful owner. Two years later, Master_Gauge_List_FINAL_v7.xlsx lives in a shared drive nobody dares to clean. Certificates sit in email attachments. Renewal dates depend on whoever happens to remember. And then the auditor picks one instrument at random and asks for its history.

  • Reminders live in one person's head, vacations and turnover silently break them.
  • Certificates scattered across drives, thirty-minute searches during live audits.
  • Out-of-tolerance traces take days, reconstructing what a bad gauge touched, by hand.
  • Every surveillance audit starts with a scramble, the pre-audit weekend is a tradition now.

We kept watching capable quality managers lose weekends to spreadsheet archaeology before every audit. Calibration tracking isn't a hard software problem, it's a custody problem. So we built the register we'd want to hand an auditor: boring, deterministic, impossible to argue with.

Frequently asked questions

Do you replace our calibration lab?

No. GaugeKeeper organizes deadlines, certificates and evidence around whichever lab you already use. Your lab stays; the chaos goes.

What happens to my existing spreadsheet?

The import wizard maps your columns and shows a dry-run report before committing anything. Your data stays exportable forever, one click, full ZIP.

Is this another AI product?

No, deliberately. Deterministic software means auditors can inspect exactly how every record was created, timestamped and stored. No black boxes in your quality system.

Who can see our data?

Only accounts in your organization. Audit events are append-only and database-enforced. EU-friendly hosting available for European customers.

When do we pay?

Not during the waitlist. Founding members lock $29/mo for life at launch, cancel anytime. We email exactly once, when doors open.

What if our instruments aren't fancy?

Especially then. Hand tools, thermometers and shop scales cause most audit findings, precisely because nobody built proper records for them.
