How does the free first merge work?
Your first complete verified merge is free. You can play and share that first result even if you do not buy the Lifetime Unlock. Creating future merges requires the one-time unlock.
How do I restore Lifetime Unlock?
Open the Lifetime Unlock screen and choose Restore Purchases. Use the same Apple Account that originally purchased the unlock.
Where do I add recordings?
Choose Add Recordings and select audio files through the iOS Files picker. Files stored in iCloud Drive or another provider may need to download before iOS passes them to Audio Joiner.
What format does Audio Joiner export?
The current version exports one M4A (AAC) file. MP3 and WAV export are not part of the current release.
Does Audio Joiner change my original recordings?
No. Ordering and trimming are stored as project edits inside Audio Joiner. The original source files you selected are not modified.
Where is my exported file?
After export, use Share Result to save the M4A file to Files or send it to another destination available in the iOS Share Sheet.
I dismissed the upgrade screen. Did I lose my first result?
No. Dismissing the upgrade screen does not remove the first free result. It remains available to play and share.
