Record now. Save after.
Airtime records into a rolling 100-second buffer while the app is open, so the moment you didn't expect to matter — already happened. Hit save, scrub back, keep exactly what counts.
Always rolling
Records continuously while the app is open. No trigger needed.
Save after the fact
Scrub back up to 90 seconds, any time. Catch what you missed.
Preview before you keep it
Trim and confirm before anything touches your camera roll.
