iSpeed Speedometer vs A

iSpeed uses your iPhone's GPS to display speed, heading, and trip data. Select between mph, km/h, and kts units of measurement. iSpeed also shows current weather conditions based on your latitude and longitude. It has full trip functionality. iSpeed will work for either your car, boat, bike, or while you walk. Features Include: - The Speed View shows your speed, heading, course, altitude, odometer, trip and drive details. It also shows the current and next 24 hour weather conditions. Your current GPS accuracy is displayed at the bottom. - The Data View displays the raw GPS location, speed, heading, trip data, and current battery status. - The Settings View allows you to set the unit of measurement and compass winds. --- Notes: --- Works on the iPhone running iOS 14.0 or later. The weather requires a data connection to display information. Continued use of GPS running in the background can dramatically decrease battery life. Have a safe trip!

A-EFIS works perfectly with the internal sensors of your iPhone/iPad The only difference of this, free, version with the paid version is that this version is in black and white. A-EFIS makes use of digital filtering methods and state-of-the-art stochastic models in order to achieve exceptional accuracy and robustness. ATTENTION: A-EFIS ONLY WORKS ON AIRPLANES. NOT TO BE USED IN HELICOPTERS OR LAND VEHICLES BECAUSE INDICATIONS WILL NOT BE CORRECT. USE ONLY IN AN AIRPLANE! Features: - Artificial Horizon (AHRS) - Ground speed (via GPS) - Altimeter (via GPS) - Vertical speed (via GPS) - Turn coordinator - Slip ball - Compass - True course indicator (via GPS) - Deviation from true track indication A-EFIS has been extensively tested on ultralights, LSA, general aviation and even airliners. Hint: To use A-EFIS in an airliner, just sit close to a window (in order for the device to be able to receive the GPS signal), put the device in a stable position and press "AHRS calibration" when the aircraft is in leveled flight. You will practically have the same flight data as the pilots in the cockpit! IMPORTANT NOTICE: A-EFIS is not a certified aviation instrument. Do not rely on A-EFIS as your only navigation aid.
