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.

Upliftic

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.
