trueband Drift Watcher
Desktop spectral-monitoring software for laboratory and QC teams on macOS, Windows, and Linux.
Review historical scans. Watch for new arrivals.
USD 2,000 per designated workstation per year, before applicable taxes, billed annually.
Passive folder watching
Choose a local folder for compatible exports. While Drift Watcher runs, it checks for new files and brings supported scans into the local workspace. New arrivals appear beside your saved reference, ready for a human review.
An arrival is a prompt to investigate, not an automatic diagnosis or quality decision.
How watched folders workThe film · 01:08
Start with historical spectra. Let a watched folder bring later scans into view. Follow the measured difference through human review, a recorded response, and a report.

From signal to saved decision
Start with historical scans, then let a watched folder passively bring supported new files into the local workspace while Drift Watcher runs. Arrival notices show when there is new work to review.

Examine recorded contextPCA and recorded fields can suggest the next check without being presented as a cause.
Scientific integrity
Drift Watcher presents spectral differences and recorded context without claiming a diagnosis, calibration result, or proven cause.

Questions before evaluation
No. Drift Watcher supports comparison and investigation of spectra. It does not validate the prediction accuracy of a calibration model.
Yes. While Drift Watcher is running, it checks a selected local folder for supported new exports, adds readable scans to the local workspace, and shows new arrivals for review. Optional desktop notifications depend on operating-system permission; this is not a cloud monitoring service.
It helps you examine recorded sample and instrument information beside the spectral pattern. Associations can guide an investigation but do not prove cause.
Imported spectra and review records remain in the local application workspace. Sign-in, entitlement checks, and product updates use defined network services.
After qualification, suitable teams can receive a 30-day installed evaluation with a setup session and a review session.
No. Evaluation installers are provided directly after a compatibility and workflow review.
