A companion app to the Lightspeed Delta Zulu ANR headset, the Lightspeed app for iOS features an array of integrated features to keep pilots and passengers safer during flight. Track CO Sensors for Safer Flying The Lightspeed app allows pilots to check the CO levels in the aircraft during flight, using a CO sensor built right into the Lightspeed Delta Zulu headset. The sensor provides real-time smart alerts via the proprietary Kanari™ smart alert technology. Historical data can be stored, reviewed, and analyzed after use and during the flight(s). Personalize Audio with HearingEQity™ The Lightspeed app introduces a built-in audio equalization system called HearingEQity™ designed to compensate for individual hearing loss. Through an automated 12-frequency hearing test taken through the app, HearingEQity sets the hearing level in each ear in a variety of frequency bands of the Lightspeed Delta Zulu headset to create an individual hearing profile and compensate for any hearing variations between ears. Record Conversations, Archive Flight Recordings, and More... The Lightspeed App allows pilots to record radio conversations, playback transmissions, draw diagrams, and archive flight recordings for post-flight briefings and training.

ReceptionRating · Positive reviews · Number of ratings

TwoTenDegrees holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: Lightspeed App has 49 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 12% of Lightspeed App's written reviews are positive against 0% of TwoTenDegrees's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lightspeed App ships an update every 6 months, TwoTenDegrees every 9 days. The most recent releases landed on October 14, 2026 and September 27, 2026 respectively.
