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.

Verdict
The clearest difference is review sentiment: ACE at 80% against Lightspeed App's 12%. ACE also leads on rating (5.0 vs 3.3). Lightspeed App's advantage is ratings volume (49 vs 5) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ACE 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 5, so its average is the more settled of the two. Written reviews point the same way: 12% of Lightspeed App's written reviews are positive against 80% of ACE's.
