Internal barometer is used on supported devices for better precision (from iPhone 6/6+ and newer iPads). If more accuracy is needed, a portable weather station can also be used. Application can run without GPS, WiFi and internet. If you're in internet range, you don't need to supply any data. If you're out of internet range, all you need to supply is the outside air temperature. Great tool for pilots, drag racers, engine tuners, or anyone who needs to conveniently find their Air Density, Density Altitude, Dyno Correction Factor and rest of calculated data. No ads or in-app purchases. The application is made up of three tabs that are described next: • Results: In this tab are shown: - Air Density - Density Altitude - Relative Air Density (RAD) - Dew Point - SAE - Dyno Correction Factor - SAE - Relative Horsepower - Station Pressure - Saturation Vapor Pressure - Virtual Temperature - Actual Vapor Pressure - Cumulus Cloud Base Height - Dry Air - Dry Air Pressure - Volumetric Content of Oxygen - Oxygen Pressure In addition, the parameters used for the calculations are showed and can be changed (time, temperature, humidity, pressure and altitude). For each of the parameters there is a detailed explanation (just tap on any parameter). • History: This tab contains the history of all calculating data. If you change the weather, the new data will be saved in history. • Weather: In this tab, you can set the values for current temperature, pressure, altitude and humidity. Also this tab allows to use the GPS to get the current position and altitude, and connect to an external service (you can choose one weather data source from several possible) to get the weather conditions of the nearest weather station (temperature, pressure and humidity). You can manually select which type of atmospheric pressure you are working with (for example if you use portable barometers, weather stations): - sea level pressure QNH - sea level pressure QFF - station pressure (barometric pressure) In addition, this application can work with a pressure sensor built into the iPhone. You can see if it is available on your device and turn it on or off. Also, on this tab, you can enable alerts about possible carburetor icing. The app let you use different measure units: ºC y ºF for temperatures, meter and feet for altitude, and mb, hPa, mmHg, inHg y atm for pressures. If you have any doubt about using this App, please, contact us. We answer every question, and we take care of all comments from our users to try to improve our software. We are also users of this application. ## Key features - Air Density Calculation - Density Altitude Calculation - Dyno Correction Factor - Weather Data Integration - GPS and Barometer Support - Offline Functionality - Bluetooth Weather Station Support ## Chart rankings - #112 in Top Paid · Sports (US App Store) ## Recent user reviews (10 of 19) All indexed reviews: https://appshunter.io/ios/app/airlab-air-density-and-altitude/id1456458659/reviews.md ### 1/5 — Stopped working! *2024-06-30* See above. Just sits and spins. Never gathers new data. ### 1/5 — Stopped working! *2024-06-28* See above. ### 5/5 — Air lab *2022-03-30* The best app out there. I have COPD and use this app every day multiple times. All I know is when I have problems I check it and the pressure is down a lifesaver. Thank you. I know it is not for this purpose but it helps. Thank you.! ### 5/5 — Must have *2020-01-02* Must have for engine tuners. Helping me for creating jetting chart. ### 5/5 — Good *2019-12-26* Must have for tuners to create jetting chart for carburetors engines. ### 5/5 — Must have *2019-12-24* Must have for engine tuners! ### 5/5 — Very useful *2019-12-19* Very useful for making my own jetting chart. ### 5/5 — Good *2019-04-08* Easy interface, fast GPS and weather acquistion. Bravo! ### 5/5 — Must have *2019-04-06* Easy to use and very valuable information. ### 5/5 — Маст хэв для настройщика двигателей *2019-04-05* Приложение полностью копирует функционал AirLab Jet-Tech Pro, которая стоит 300 баксов, тут же в сто раз дешевле, и интерфейс в сто раз круче )) Здорово :) Маст хев. ## Frequently asked questions about AirLab ### What is AirLab used for?

Now you can manually select which type of atmospheric pressure you are working with (for example if you use portable barometers, weather stations): - sea level pressure QNH - sea level pressure QFF - station pressure (barometric pressure) • We added the ability to leave text notes for each history in 'History' tab. To do this, open any History, enter edit mode and add a note • Now you can manually select the translation language. Application contains many special terms and sometimes translations that we offer are not always good. We are sorry. Now, if your phone (for example) in German, but you are unhappy with the translation you can switch to English (for example) only in this app (you don't have to change locale of device). You can find this feature on 'Weather' tab at the very bottom • New feature: Weather for custom location. You can manually select any place in the world and all data will be calculated for it (for altitude and current weather conditions in this place) • Improved functionality for the feature 'Weather for custom location'. We added a search bar where you can enter the location name. Search places easier and faster now • We reworked the altitude determination algorithm for the 'weather for custom location' feature.
