Instant and location accurate Density Altitude calculator/instrument app for iPhone and iPad that also finds relative air density (RAD), altimeter setting, relative humidity, specific humidity (grains/lb) and more. Super useful for pilots, especially in the backcountry. Many other uses for engine tuning, racing, sports, etc. * Seamlessly integrates weather data, GPS and your phone's onboard barometer to quickly and accurately calculate your density altitude, altimeter setting, relative air density, and more. * Takes humidity into account in all calculations, making it more accurate than the typical dry bulb approximation formula used by AWOS/ASOS, etc. * Works anywhere. Great without cellular connection as well, which makes it all the more useful in the backcountry and far away from ASOS/AWOS stations. * Location Search: Find atmospheric data (Density Altitude, etc.) at any point on Earth, from anywhere! Data Sensed and Calculated (all calculated with humidity): * Density Altitude * GPS Altitude * Temperature * Altimeter Setting * Absolute Pressure * Dew Point * Relative Humidity * Specific Humidity (grains/pound) * Air Density * Relative Air Density (RAD) * Dyno Correction The quickest way to get your Density Altitude! On the iPhone 6/6+ and newer iPads, it will use the built-in barometer and GPS. If you're in cell range, you don't need to supply any data. If you're out of cell range, all you need to supply is the outside air temperature. Designed not to need an internet connection, so it will work anytime and anywhere you need it. Great tool for pilots, drag racers, engine tuners, golfers, or anyone who needs to conveniently find their Density Altitude, Altimeter Setting, Relative Aid Density (RAD), Specific Humidity or Absolute Pressure.

Would like the option to save locations or drop pins for favorites. This is beneficial for monitoring trends for future outings. Thanks! ### 5/5 β€” Great App but needs Apple Watch Widget *2025-09-07, version 2.8* This app is great for its simplicity and ease of use. I also like how the App Store indicates that no data is collected from the app. I just wish it could integrate into the display for the Apple Watch as this is something I often reference when towing in the mountains. ### 4/5 β€” Drag Racer *2025-08-29, version 2.8* We are in the test stage for this app. It appears reasonabley accurate and consistent. I’m not sure how close it is to the track though. Still assessing ### 5/5 β€” Excellent but wish there was a watch app *2024-10-16, version 2.8* By far the best density altitude app. I just wish I could get it as an Apple Watch app with complications for my watch face. ### 5/5 β€” Great for car racing *2022-12-22, version 2.6.3* Great for car racing. ### 5/5 β€” Better GPS Accuracy *2022-10-23, version 2.6.3* This has always been a great App, but depending on location, GPS altitude for me could sometimes be off. With this new App update, 2.6.3, it provides increased satellite accuracy. Every reading for me is now completely accurate, every single time. An excellent App now made better! ### 3/5 β€” GPS elevation *2022-10-21, version 2.6.2* GPS elevation doesn’t always update on the fly reliably. Example you check at bottom of a hike. Then gain 2,000’ elevation after hike. Check app again. GPS altitude/elevation doesn’t change. Don’t see how it can be accurate given this occurrence ### 5/5 β€” Great app I like it! *2022-06-22, version 2.6.2* I use it to backup my weather station data on my dyno as well as when I’m playing around with my car. πŸ‘ ### 5/5 β€” Long Rang Precision *2021-04-13, version 2.4* Works good. Doesn’t need to be perfect, just give an idea of whats going on. Good enough to right info on a dope card. ### 4/5 β€” Make the Location changeable. *2020-12-05, version 2.3* It would deserve a five star rating if I could manually change the location. ## Frequently asked questions about Density Altitude + ### What does the Density Altitude+ app do? This app calculates density altitude and other atmospheric data like relative air density, altimeter setting, and humidity. It uses your location, GPS, and your device's onboard barometer for accurate readings, even without a cellular connection. ### What are the key features of Density Altitude+? Key features include instant and location-accurate density altitude calculation, integration of weather data and GPS, humidity-compensated calculations for higher accuracy, and the ability to search atmospheric data for any point on Earth. ### Is Density Altitude+ free to use? Yes, the app is completely free to use and does not contain any ads or in-app purchases. This ensures an uninterrupted experience for all users. ### What devices is Density Altitude+ compatible with? The app is designed for iPhone and iPad.

The issue was a recently added iOS privacy setting. If you're a current user and are still not prompted to allow the app to access the barometer, you can go into Settings->Privacy & Security->Motion & Fitness and enable access for Density Altitude+ there. Thanks for your support! Reach me at densityaltitude@rateofclimb.com ### 2.7 β€” 2023-07-01 This version uses a new Elevation API provider since our previous Elevation API provider is shutting down. This only affects the location search feature, and accuracy should be even better! Follow us on Instagram @RateOfClimbIndustries. Thanks for the support! ### 2.6.3 β€” 2022-10-23 - Increased GPS accuracy in certain situations. This should make GPS elevation data more accurate in areas with obstructions, etc. ### 2.6.2 β€” 2022-06-22 - UI improvements Reach us any time at densityaltitude@rateofclimb.com. IG: @rateofclimbindustries Thanks for the support! ### 2.6.1 β€” 2021-10-26 Improvements to the way Location Service permissions are handled. App would in certain edge cases crash if Location Services were turned off and user tapped GPS Location button. This is now fixed. email us anytime at densityaltitude@rateofclimb.com Follow us on Instagram @rateofclimbindustries ## Apps similar to Density Altitude + | App | Rating | Price | Category | | --- | --- | --- | --- | | [FlyQ+ EFB](https://appshunter.io/ios/app/flyq-plus-efb/id915571252) | 4.1 (892) | Free | Navigation | | [xcNav](https://appshunter.io/ios/app/xcnav/id1616930706) | 4.0 (4) | Free | Navigation | | [RaceTools](https://appshunter.io/ios/app/racetools/id1578074779) | 4.9 (86) | Free | Navigation | | [Sporty's E6B Flight Computer](https://appshunter.io/ios/app/sportys-e6b-flight-computer/id371817955) | 4.9 (5,299) | $9.99 | Navigation | | [NRST](https://appshunter.io/ios/app/nrst/id828514590) | 4.5 (8) | Free | Navigation | | [Altimeter+](https://appshunter.io/ios/app/altimeter-plus/id417204570) | 4.5 (700) | $1.99 | Navigation | ## More apps by Rate Of Climb Industries - [NWS Weather: Deep Weather](https://appshunter.io/ios/app/nws-weather-deep-weather/id528748182) - [Zulu Time Widget - GMT/UTC](https://appshunter.io/ios/app/zulu-time-widget-gmtutc/id937389624) All apps by Rate Of Climb Industries: https://appshunter.io/developer/528748185 ## Related topics [density altitude](https://appshunter.io/ios/topics/density-altitude) Β· [density altitude meter](https://appshunter.io/ios/topics/density-altitude-meter) Β· [density altitude calculators](https://appshunter.io/ios/topics/density-altitude-calculators) Β· [air density calculator](https://appshunter.io/ios/topics/air-density-calculator) Β· [air density](https://appshunter.io/ios/topics/air-density) Β· [air density online](https://appshunter.io/ios/topics/air-density-online) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
