Jet Fueling vs coolAltitude
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Jet Fueling
This app assists aircraft refueling operations and payload calculations. It helps determine desired bloc fuel, computes uplift quantities considering various factors, and performs basic fuel and specific gravity conversions. A built-in calculator is accessible via a swipe gesture.
- Payload vs. Bloc Fuel determination
- Uplift quantity calculation
- Fuel on Board (FOB) consideration
- APU fuel consumption calculation
- Fuel density input
- Basic fuel conversions
- Specific gravity conversions

"Jet Fueling" can be used by anyone involved in the process of refueling an Aircraft, and/or determining Payload in regards to Bloc Fuel and vice-versa. The first tab: "LIMITATIONS" allows to fine-tune available paylod versus desired Bloc Fuel and vice-versa... Desired bloc fuel is computed on this tab. The second tab: "REFUEL", helps compute the quantity needed to be uplifted (in Liters, US Gallons or ImpG) taking into account: - The desired quantity upon departure (Bloc), - The remaining fuel on board at the time of the computation (FOB –Fuel On Board -), - The fuel consumption of an APU or other power unit until departure, - And of course Fuel density (specific gravity for the purists). It also allows for some basic conversions (ex: USg to Lbs, L to kg etc…) as well as specific gravity conversions. On both these tabs, a basic calculator can be summoned by a swipe gesture. It is dismissed in the same way.
coolAltitude
This app provides pilots with essential tools for cold-temperature altitude corrections, approach profiles, and de-icing calculations. It integrates weather data and offers a clear interface for critical flight planning information.
- Cold-temperature altitude corrections
- Approach profile visualization
- De-icing and holdover time calculations
- FMS-style approach setup
- METAR, TAF, and runway condition integration
- Light and dark mode support

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.

Verdict
The clearest difference is rating: coolAltitude at 5.0 against Jet Fueling's 4.6. Jet Fueling's advantage is review sentiment (89% vs 60%) and price ($1.99 vs $7.99). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Jet Fueling costs $1.99 and coolAltitude $7.99 up front. Jet Fueling sells 1 one-off in-app purchase and coolAltitude sells 2 in-app purchases, starting at $7.99 per year. Whichever you choose, the download price is not the number that matters.
coolAltitude holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 7 and 7 respectively. Written reviews complicate that: 89% of Jet Fueling's written reviews are positive against 60% of coolAltitude's, so the app with the better star average is not the one people write more warmly about.
Jet Fueling ships an update monthly, coolAltitude every 3 months. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
