TowerOwl turns your Android phone into a cockpit voice recorder. It captures ATC, intercom and your own transmissions straight from your Lightspeed Zulu 4 over Bluetooth, and plays the last minutes back into your headset while the recording keeps running.
Free to record. Pro unlock CHF 19.90, once. No subscription, no account, recordings stay on your phone.
Headsets like the Lightspeed Zulu 4 can send everything you hear, intercom and radio, to your phone over the standard Bluetooth call channel. TowerOwl records that channel. Nothing proprietary, nothing to plug in.
On the Zulu 4, set DIP switch 6 (“Record Comm”) ON. Pair the headset with your phone for calls and media.
TowerOwl records to small AAC files (about 14 MB per hour), keeps going with the screen off, and marks headset drop-outs and phone calls automatically.
Missed a clearance? Replay the last 30 seconds into your headset without stopping. After the flight: bookmarks, notes, share, export.
Last 10 s to 5 min, with pause and scrub, while the recording continues.
Tap to mark a moment, label it, jump to it later. Also from the notification.
Audio is written to disk every few seconds. A dead battery loses almost nothing.
Draw clearances and diagrams with finger or stylus. Dark mode for night flying.
Play with seek, rename, add notes, share, export with a bookmark list.
Bose, David Clark and older Lightspeed models work through a recorder adapter (Pro).
