## What is MetaCAD Pocket?

Calculate Sea Time and ETA from distance and speed with a deterministic engine. Save the result as a Case linked to a local Vessel profile, reopen it after a relaunch, and export an integrity-checked case package for handoff.

Use the existing Stability workspace for quick advisory checks:
• corrected GM and KG/KM comparison
• free-surface correction
• cargo move and cargo addition effects
• heel and roll-period estimates
• water-density draft change

Designed for offline work on iPhone and iPad. Core calculations, Vessel profiles, and saved Cases use local device storage. The app is free and has no in-app purchases or subscriptions.

Important: MetaCAD Pocket supports advisory calculations and independent checks. It is not an approved loading computer and does not replace a class-approved stability booklet, vessel procedures, or professional judgement. Verify all inputs and results before operational use.
