Frequently asked questions
How do I add my videos or music?
Go to the Local tab and tap the + button to import from Files or Photos. You can also use Wi-Fi transfer to send files from a computer on the same network.
Can it play in the background or with the screen off?
Yes. Use the audio-only mode and Picture-in-Picture; playback continues when the app is backgrounded or the screen is locked.
How does the equalizer work?
Open a track and tap the equalizer to adjust the multi-band sliders, or pick a preset (Bass, Vocal, Rock, Pop, and more).
What is the private vault?
The private vault hides selected videos and music behind Face ID / Touch ID. Move items into it from the Local tab; you'll need to authenticate to view them.
How do I add subtitles?
In the player, choose Subtitles to import an .srt
file or generate subtitles automatically on-device. For audio, import an
.lrc file for synced lyrics.
How do I edit or convert a video?
Open a local video and choose Edit / Convert to trim, compress, extract audio to your music library, change speed, or create a ringtone or GIF.
Why do I see ads, and how is my privacy handled?
Ads keep the app free. We use Google AdMob and ask your permission before any tracking. See our Privacy Policy.
