coolAltitude vs Upliftic

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/

Upliftic is a fast, pilot-friendly calculator for planning and presenting aircraft fuel uplift. Enter your Current Fuel on Board (smart tri-field: total/left/right), set Target Fuel (lbs) and Trip Fuel (lbs), and get the Uplift in litres instantly—plus a clear ReFuelEU policy check using your Taxi fuel and density constant. New in 2.0: Upliftic on Apple Watch, with watch-face complications and iPhone sync. Designed for the flight deck, Upliftic keeps inputs simple, typography large, and actions obvious. Show the uplift to the refueler in a single tap using the full-screen number view. Need rounded options? Use the three +50 L quick tabs to display uplifts rounded up (e.g., 2300 L, 2350 L, 2400 L). If you're not compliant, Upliftic also provides a dedicated "Refuel EU compliant uplift" suggestion you can tap to present full-screen. Capture last-minute instructions in the always-visible WhiteBoard and open it full-screen; the text auto-fits to fill the display and stays fully readable—without scrolling—even at larger accessibility text sizes. Upliftic also includes a Wind Components calculator (crosswind/headwind/tailwind) with a simple runway + wind diagram for quick checks on the go. Everything works offline, with values persisted between sessions. Features • Apple Watch app: Digital Crown entry with ±100/±1000 buttons, uplift and ReFuelEU check, rounded-to-50 L refueller options, full-screen presenter. • Watch complications: current uplift on the watch face, or a shortcut to a new calculation. • Departure ICAO (optional): shows whether ReFuelEU applies at your departure airport, from the European Commission's list built into the app. • Trip fuel ceiling: the highest trip fuel that still complies with ReFuelEU. • Smart inputs: "Current Fuel on Board" total field syncs with left/right tanks; edit any field and the others update. • Faster entry (optional): auto-commit and hide the keyboard after your chosen digit count for Current/Target/Trip Fuel. • Target & Trip Fuel (lbs): straightforward fields with validation; Trip Fuel is optional. • Uplift result (L): instant calculation plus quick projections for Target +100/+200 lbs. • ReFuelEU policy check: banner turns green/red when Trip Fuel is set; blue when Trip Fuel = 0; grey when the departure airport is out of scope. • Refuel EU compliant uplift (when needed): additional rounded-to-50 L suggestion shown when not compliant; tap to present full-screen. • Taxi fuel (custom): set any value (lbs) and optionally override it on the main screen (clearly marked as default vs override). • Density constant (custom): default 0.567; editable and persisted. • +50 L quick tabs: three narrow buttons below the result—rounded up to the nearest 50 L, then +50 L and +100 L. • Full-screen presenter: tap a tab to show a giant litre value; auto-fits and rotates with the device. • WhiteBoard: always-visible note area; open full-screen, auto-fit text (no scrolling), readable at any accessibility text size, landscape-optimized; quick "Clear" control in the section header. • Wind Components Calculator: enter wind direction/speed and runway number or magnetic direction; get crosswind and head/tailwind plus a simple diagram; quick reset for wind-only inputs. • Accessibility & persistence: Dynamic Type support throughout, VoiceOver labels, values remembered after app restarts. • Offline by design: no network required. Why pilots like it • Built for speed and legibility on the ramp. • Clear compliance signal when Trip Fuel is provided—plus a ready-to-show compliant uplift when it isn't. • One-tap big-number display for refuelers. • No clutter: Taxi fuel and density constant you control, with quick overrides when needed. • Quick wind component check without leaving the app. Notes Upliftic is a reference aid, not certified avionics. Always verify your figures and follow your company SOPs and aircraft documentation when planning fuel.
