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 is a professional aviation tool and calculator for IFR pilots operating in cold-weather conditions. It assists with temperature corrections during instrument approaches and integrates weather, runway and de-/anti-icing data into a single, clear workflow. Designed to reduce workload and improve situational awareness during flight preparation, coolAltitude focuses on accuracy, clarity and operational usability. Some advanced features require a paid subscription. -------------------------------- What coolAltitude does • Calculates temperature-corrected altitudes for ILS (CAT I), RNAV/GNSS, VOR and NDB approaches • Requires minimal data entry, using consistent color coding for immediate interpretation • Displays corrected altitudes along the entire approach profile at relevant DME distances • Supports flight path angle (FPA) calculations for FPA-enabled aircraft • Provides vertical speed reference tables (corrected and uncorrected) for various ground speeds • Includes QNH to QFE conversion tables with temperature corrections -------------------------------- Integrated weather and runway information • Live METAR interaction with automatic propagation of relevant values, including temperature (requires subscription) • SNOWTAM decoding with braking action information • RCAM (Runway Condition Assessment Matrix) based on ICAO GRF • Support for DME shift, including threshold, touchdown zone and displaced DME references -------------------------------- De-/Anti-icing support (requires subscription) • FAA Holdover Time (HOT) Guidelines for multiple fluid types and manufacturers • Integrated HOT countdown timer to track minimum and maximum recommended holdover times • Reference tables supporting assessment of snowfall intensity • Structured storage and sharing of airport-specific de-/anti-icing procedures -------------------------------- Saved and shared data (requires subscription) • Save and reload approach presets for individual airports and procedures • Share verified, structured operational data with other users • Local override of shared data when required -------------------------------- Built for professional use coolAltitude is built by pilots, for pilots. It is designed to support decision-making during high-workload phases without replacing approved procedures. -------------------------------- Important notice coolAltitude is an advisory tool only. It is not certified for operational use and does not replace approved documentation. Use in flight operations requires approval and operation as part of the operator’s Electronic Flight Bag (EFB) in accordance with applicable regulations. -------------------------------- coolAltitude does not replace your procedures. It helps you apply them correctly, even on the coldest days. -------------------------------- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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 29, 2026 and October 26, 2026 respectively.
