Quick DA uses your devices onboards sensors (GPS and Barometric Pressure Sensor) and user data inputs making it simple to calculate Density Altitude. Store your DA calculations into the Data Log for later reference, or load past Data Logs back into the Environment Tab to further edit your DA calculation. Calculate Density Altitude using: -Ambient Air Temperature + Elevation -Ambient Air Temperature + Barometric Station Pressure -Ambient Air Temperature + Barometric Station Pressure + Relative Humidity Features and Functions: DA calculation, Location and Time the calculation was created prominently displayed Use the Environment input options that work for you Get Ambient Air Temperature from the nearest weather station Receive your current Field Elevation using the device’s GPS Use the Map Screen Feature to select a point on the map and receive its elevation Select between Street, Terrain, and Satellite map options Use your device’s Barometric Pressure Sensor for real-time pressure readings Use the Advanced Pressure Input option for converting Sea Level Adjusted Pressure Get your current Relative Humidity from the nearest weather station Press the + action button to create a Data Log of your DA Calculation Data Log entries display: location, date, time, DA, and input variables used to calculate DA Use the arrow action button to load data back into Environment Tab Use the Clear Button to clear all Environment Tab inputs User selectable Dark, Color, and Light app themes Use Feet or Meters and Fahrenheit or Celsius Quick DA uses Apple MapKit for map interaction, search, road, and satellite imagery. Terrain tile overlays are powered by MapTiler OSM Contributors. Elevation data for selected locations is provided by the USGS Elevation Point Query Service.

Quick DA utilizes your device's onboard sensors like GPS and barometric pressure, along with user-provided data such as ambient air temperature, elevation, and relative humidity, to compute density altitude. ### Can I save my density altitude calculations with Quick DA? Yes, Quick DA allows you to store your DA calculations in a Data Log. This log displays the location, date, time, density altitude, and the specific input variables used for each calculation. ### What are the different ways to input environmental data in Quick DA? You can calculate density altitude using ambient air temperature with elevation, ambient air temperature with barometric station pressure, or ambient air temperature with barometric station pressure and relative humidity. It can also fetch temperature and humidity from the nearest weather station. ### Does Quick DA offer different map views? Yes, Quick DA features a Map Screen with selectable Street, Terrain, and Satellite map options. You can select a point on the map to receive its elevation data. ### What units does Quick DA support? Quick DA offers user-selectable units, allowing you to choose between Feet or Meters for altitude and Fahrenheit or Celsius for temperature. ### Is Quick DA suitable for offline use? While Quick DA uses online services for weather data and map imagery, core density altitude calculations can be performed using onboard sensor data and user inputs, offering some offline functionality for calculations. ### How often is Quick DA updated? The latest version of Quick DA is 1.1.3.9, last updated on July 7, 2026. Updates typically address bug fixes and feature enhancements. ### What is the age rating for Quick DA? Quick DA has an age rating of 4+, making it suitable for a wide range of users. ## Version history (last 2 releases) ### 1.1.3.9 — 2026-07-07 - New Temperature Forecast Feature.
