The Aithre Connect application provides the first world-wide Aithre Pilot Community for instantly sharing PIREPS, turbulence data, and other weather data and is used to pair with Aithre devices to monitor health and oxygen in flight. The Aithre Connect app includes a WatchOS companion app.

AITHRE PILOT COMMUNITY WEATHER (APC). THE APC is new for version 8.0. View near-real-time weather conditions for precision 3D coordinates in space as reported and provided by other APC members. The weather is shared using one-touch PIREPs in the app and automatically via the included in-app turbulence monitor. Aircraft with the installed Aithre Metis weather system also contribute near-real-time temperature, humidity, and dew point levels from actual flight recordings. All data is anonymous and private and there is no login ever required. However, an optional anonymous AithreID can be obtained by verified pilots from Aithre to allow trust and reputation building within the community.

AITHRE ASSISTANT. The assistant is new for version 7.0. This assistant enables quick speech based lookup of frequencies for airports, airport information, and runway information. Quick airport frequency lookups can be asked for and provided via text and audible speech, via a paired aviation headset. A nearest function automatically provides you with quick access to nearest airports, runways, and frequencies during flight.

CHECKLISTS. Create custom checklists for quick access. Quickly check off items to support pilot decision making.

PULSE OXIMETRY. The Aithre Illyrian is a wireless enabled smart pulse oximeter with red/infrared dual channels that can be worn on the center forehead or under the earlobe. Using a flat, low profile sensor pad and simple USB power, the Illyrian oximeter broadcasts pulse rate and blood oxygen data to your iOS and companion WatchOS. The data is presented in real-time and in a trend graph including up to 12 hours of data - along with pressure altitude information. Notification is provided for drops in oxygen percentage. Ideal for pilots where continuous blood oxygen monitoring is important. In aviation, the pulse oximetry can also be displayed on glass panel avionics, including G3X and Dynon when used with the Aithre Shield EX3.

PORTABLE OXYGEN TANK MONITORING. The Aithre Altus is a wireless enabled portable O2 tank monitor that puts oxygen tank pressure readings on your iOS and WatchOS device. In addition to discrete pressure readings, there is also a 4 hour historical trend provided along with a use rate and time remaining indication. Pressure altitude is determined using an on-board pressure altimeter. Notifications are provided for pressure levels. Ideal for aviation where portable oxygen is used. In aviation, the portable tank PSI can also be displayed on glass panel avionics, including G3X and Dynon when used with the Aithre Shield EX3.

CARBON MONOXIDE DETECTOR. The Aithre Shield is a wireless enabled carbon monoxide detector that is highly sensitive and portable. CO levels and trend data is transmitted wirelessly in real-time to your iOS and your WatchOS device. Notifications for crossing CO thresholds are provided. Ideal for use in the field of aviation.

G-FORCEs. The Aithre Connect app further monitors acceleration in any direction and plots the max acceleration/g-force every 12 seconds. This historical acceleration data is useful in determining the comfort of your passengers during flight or for monitoring stresses on the aircraft during aerobatic flight.

TRIP HISTORY. The trip history is new for version 7.3. When used with the Illyrian and/or Shield devices, the trip history feature keeps health and CO data for each trip. These trips are accessible within the app and as external CSV files (spreadsheet files).

Update: Lightning in a Bottle

Through various updates and Aithre’s demonstrated commitment to safety and their product line, they have now achieved a wicked risk-mitigation solution to the carbon monoxide threat in the everyday general aviation pilot world. Aithre didn’t just talk about future improvements, they did something about it in quick fashion.

When it comes to CO awareness I trust my life and my family’s lives to Aithre.

Chris, thanks for your feedback. We released a new update today pending review by Apple.

Added ad­di­tion­al Siri and pop­up no­ti­fi­ca­tions to now in­clude: con­nec­tion sta­tus, dis­con­nec­tion sta­tus, car­bon monox­ide warn­ings above 2, 10, and 50 ppm, oxy­gen tank de­ple­tion be­low 500 psi, pres­sure al­ti­tude greater than 12500 ft and 15,000 feet. Also added a user set­ting for a cus­tom car­bon monox­ide thresh­old warn­ing, which is pro­vid­ed via Siri and pop­up notif­ication. Ad­di­tion­al­ly added a user set­ting for a cus­tom pres­sure al­ti­tude warn­ing thresh­old, which is pro­vid­ed via Siri and pop­up notif­ication. These ad­di­tion­al user set­tings and Siri no­ti­fi­ca­tions en­able en­hanced safe­ty in flight and can be pro­vid­ed via the avi­a­tion head­set when the head­set is paired to the iOS de­vice run­ning this ap­pli­ca­tion.

Also added ad­di­tion­al sup­port for pres­sure al­ti­tude de­ter­mi­na­tions, FAA oxy­gen re­quire­ments that are au­to­mat­i­cal­ly de­ter­mined based on pres­sure al­ti­tude, flow rate, tank time re­main­ing, and ad­di­tion­al func­tions with re­spect to Aithre Al­tus por­table oxy­gen tank man­age­ment.

Does work....

Disappointed to find that it does not rotate? Frequently pilots use their iPads in landscape mode or upside down. I contacted the developer. They listened. It now rotates. Changed my rating. Does not allow to change degrees from Celsius to Fahrenheit.

Developer Response ,

Version 7.8 now allows landscape or portrait mode for iPad and also split screen and multitasking.
