## What is coolAltitude?

coolAltitude brings cold-temperature altitude corrections, approach profiles and de-icing tools into one focused workspace for pilots.

ALTITUDE CORRECTIONS
Enter the temperature and approach data, compare entered and corrected altitudes, and see the result in a clear approach profile. Select the correction method and rounding option for your workflow. DME shift helps put distance references in context.

APPROACH SETUP
Use the FMS-style interface to work with airport, runway and approach data. A structured display and dedicated keys keep the setup readable alongside the profile.

DE-ICING AND HOLDOVER TIME
Select the applicable conditions, fluid type and concentration. Review the available holdover guidance and keep the countdown visible during your workflow.

WEATHER AND RUNWAY CONTEXT
Consult METAR, TAF and runway-condition information alongside your calculations. Online information depends on the availability of the connected services.

READABLE IN LIGHT AND DARK
Clear colour roles distinguish inputs, corrected values and shifted values. Light and Dark appearances support different lighting conditions, with restrained surfaces and readable controls.

Some features require an in-app subscription. Check the in-app purchase screen for the features included, subscription terms and current pricing.

Use current operational information and the procedures applicable to your aircraft and operation when assessing results.

### 1/5 — Waste of money

*2026-10-08*

Don’t be fooled. It’s a very basic 5 or so inputs to make generic changes. You can’t enter an individual runway or aerodrome approach. You can’t create an approach to any operational standard. Obviously, it pushes you to subscribe for any real features. 

Don’t be fooled by the marketing sales pitch.

All you get is on the screenshot. No real application where you can actually create waypoints, distances and levels.

A waste of perfectly good money.

Don’t throw good money away on this unusable pretend App!

### 5/5 — Theme

*2025-01-22*

Previous dark thame was better.

### 5/5 — Excellent!

*2024-03-25*

This is an excellent review; it fully meets the current operational requirements.
Congratulations, you did a great job.

**Developer response:** Thank you!

### 1/5 — Not working

*2018-09-06*

App keeps crashing, calculations are wrong and the design is too complicated ! That’s a theft! don’t download it !!!!

### 4/5 — Does what it says

*2015-10-04*

Would have 5***** if it worked for positive high temps to help with warmer than ISA RNAV approach baro cross checks.

## Version history (last 5 releases)

### 5.0 — 2026-11-03

Version 5.0 brings a refreshed interface with clearer colour roles, subtle glass surfaces and updated menus.

The FMS-style interface has a lighter appearance in Light mode and turquoise entries in Dark mode.

Layouts adapt to both displays of iPhone Duo.

### 4.9 — 2026-10-21

New: TAF for the selected airport

• Tap the TAF label next to the approach name to see the latest TAF, with each change group (BECMG, TEMPO, FM, PROB) on its own line.
• Included with Save & Retrieve Approach Data, together with the METAR.
• The TAF is a forecast and is shown for reference only – unlike the METAR, it is never applied to the calculation.
• The last TAF stays available offline; an expired TAF is marked.

Snowfall intensity table
• The notes below the table now follow the FAA Holdover Time Guidelines, Winter 2026–2027, word for word.
• The last row now reads ≥3 ½ SM / ≥5600 m, as in the FAA table.

### 4.8 — 2026-10-12

Corrected snowfall intensity estimate

The snowfall intensity shown next to DAY/NIGHT in the de-/anti-icing panel (estimated from the METAR visibility) now follows the visibility ranges of the FAA table exactly.

• Earlier versions applied each table row only up to its nominal visibility – for example the 800 m row up to 800 m instead of up to 1000 m. In some ranges the app therefore showed a lighter intensity than the FAA table, e.g. Moderate instead of Heavy at 500 m by day at -1 °C and below.
• Visibilities reported in statute miles are now matched to the statute-mile column of the table. Reports such as 1/4 SM, 1/2 SM, 3/4 SM and 1 1/2 SM were affected.
• Visibility reported as M1/4SM (less than 1/4 SM) is now recognized. Earlier versions showed no estimate for it.
• The FAA table in the app (snowflake button) was correct and is unchanged, as are all holdover times.

We recommend updating before winter operations.

### 4.7 — 2026-09-25

Updated for the FAA Holdover Time Guidelines, Winter 2026–2027.

• Holdover tables now show the FAA source document and issue date.
• Snowfall intensity table updated to the 2026–2027 FAA edition.
• New: search for a fluid by name in the fluid list.
• Improved reliability of data synchronization when coming back online.
• Fixed a rare crash on first launch.

### 4.6 — 2026-09-01

• Various interface improvements and usability refinements
