A clean, professional desktop interface built for accredited metrology labs.

New in v2.0

The most advanced Cali yet

Version 2 brings true measurement accuracy, multi-site teamwork and audit-ready compliance — built for labs that sell results.

🌡️
True, condition-corrected results
Cali calculates thermal expansion, temperature and air-buoyancy effects so every certificate shows the real result — verdicts based on the corrected value across all disciplines.
📈
Predictive recalibration intervals
Drift analytics project when each instrument will drift out of tolerance and recommend a safe calibration interval — recalibrate on evidence, not guesswork.
☁️
Multi-user cloud sync
Work across computers and sites while staying offline-first. Changes sync securely through your own server; data is encrypted before it ever leaves the PC.
🛡️
Cloud backup (OneDrive & more)
Point Cali at a cloud-synced folder for automatic off-site backups. The live database stays local; only encrypted backup copies go to the cloud.
🌍
10 languages, RTL-ready
A full interface and certificates in 10 languages including Arabic — reach accredited labs across the globe.
✍️
21 CFR Part 11 e-signatures
Advanced electronic signatures with signing meaning, password policies, session timeout and a tamper-evident audit trail — ready for regulated (GxP) environments.
