## What is Varnish Calculator?

Varnish Calculator is a professional calculator for varnish and coating consumption, built for anyone who needs precise, repeatable numbers on the shop floor.

FEATURES
• Internal and external coating calculators
• Recalculation tool for adjusting existing jobs
• Production planning for batch work
• Varnish management — save your own varnishes and external products with their technical data
• Calculations based on SCV (solids content by volume), wet/dry densities, and layer thickness
• Apple Watch companion app with live sync — check and calculate on your wrist

DESIGNED FOR PRECISION
Enter values manually or use your saved varnish data to auto-calculate SCV, applied weight, and required layer thickness — internal or external, per container or per square meter.

PRIVACY FIRST
Varnish Calculator works entirely on your device and your paired Apple Watch. No accounts, no tracking, no data collection.

Available in English, Czech, Slovak, Spanish, French, Portuguese, Norwegian, Ukrainian, Arabic, and Hindi.
