No-ICE
Real-time de-icing hold-over time manager with official FAA and Transport Canada tables.
- Official FAA and Transport Canada hold-over time tables — fluid types I, II, III, and IV
- Precision timer with Live Activity, Dynamic Island, and haptic feedback for eyes-free monitoring
- Available on iPhone, iPad, and Mac (M1+) for €2.99 — no data collected
No-ICE is a professional de-icing decision tool for pilots and flight crew. It provides immediate access to official FAA and Transport Canada hold-over time tables and runs a precision countdown timer that stays visible on the lock screen and Dynamic Island — so you can monitor remaining protection time without breaking the pre-departure flow.
Hold-over time tables
No-ICE contains official hold-over time (HOT) data for fluid types I, II, III, and IV as published by the FAA and Transport Canada. Tables cover the full range of precipitation types and intensities defined in regulatory guidance, including:
- Light, moderate, and heavy precipitation — snow, freezing drizzle, freezing rain
- Outside air temperature ranges — from near 0°C down to the operational limits of each fluid type
- Flaps/slats factor applied automatically based on aircraft configuration
Precision timer
The core of No-ICE is a high-precision countdown timer that starts from the selected hold-over time and runs throughout the pre-departure sequence:
- Pause and resume — for interrupted sequences or ground delays
- Visual feedback — colour progression as HOT approaches expiry
- Haptic feedback — tactile alerts for eyes-free operation during busy phases
- Live Activity — hold-over countdown visible on the iPhone lock screen without unlocking
- Dynamic Island — persistent timer display on supported iPhone models

Frequently asked questions
What is a de-icing hold-over time and why does it matter?
Hold-over time (HOT) is the estimated time that de-icing or anti-icing fluid remains effective after application, protecting critical surfaces from ice contamination. Exceeding HOT before takeoff is a serious safety risk — No-ICE keeps the timer visible and accessible so pilots can monitor it without distraction.
Which fluid types does No-ICE support?
No-ICE covers all four standard de-icing fluid types — Type I, II, III, and IV — across the full range of weather conditions defined in FAA and Transport Canada guidance.
Which regulatory tables does No-ICE use?
No-ICE uses official hold-over time data published by the FAA (Federal Aviation Administration) and Transport Canada. These are the same tables referenced in airline operations and accepted by major civil aviation authorities.
What is the flaps/slats factor and how does No-ICE handle it?
Flaps and slats extend the surface area exposed to precipitation, which can reduce effective hold-over time. No-ICE automatically applies the correct flaps/slats factor to the displayed HOT so the result reflects the actual aircraft configuration.
Does No-ICE work on Mac?
Yes — No-ICE runs on Mac with Apple Silicon (M1 or later) via macOS 14.0+, in addition to iPhone (iOS 17+) and iPad (iPadOS 17+).
What is Dynamic Island integration used for?
When the timer is running, No-ICE uses Dynamic Island (on supported iPhone models) and Live Activity on the lock screen to keep the remaining hold-over time visible without unlocking the device — useful during pre-departure procedures when the phone may be holstered.
Does No-ICE collect any user data?
No. No-ICE does not collect, transmit, or store any user data. The app works entirely on-device.
