## What is SUB?

SUB-ZERO is the all-in-one ice operations platform designed to help arenas deliver elite ice conditions, improve efficiency, and make smarter, data-driven decisions every single day.

## Version history (last 5 releases)

### 1.4 — 2026-08-11

Flood / Cut Log Results
View your submitted flood and cut logs directly in the app. Switch between a card view:  one log at a time with a page-turn animation : and a grid view for scanning across records. Choose which columns you see, filter by asset or operator, and search across your full history. After submitting a new log you're taken straight to the results.

Redesigned Dashboard
A new Inspection Overview showing your last 30 days at a glance, an activity streak across everything you log, your latest ice depth check with facility and ice pad, and a Last Flood card with water, snow and previous program. Water, flood and snow consumption is now a single clear chart.

Français
Switch the entire app between English and French from the side menu. Menus, screens, buttons, field labels and dates all follow your choice.

Dark Mode
Toggle light and dark from any screen. Your preference carries across the whole app.

Built for iPad
Screens now use the full display instead of a narrow column.

Faster and Smoother
Large log histories load in pages instead of all at once, so results open quickly even with thousands of records. The new log form loads faster and matches the SUB-ZERO look. The side menu has been rebuilt with clearer icons throughout.
