This app allows you to easily import your audio files, which will only be visible and playable within the app — not in a standard media player. You can conveniently play them directly inside the app. A key feature is the automatic recognition of time formats in the file name — for example, names like "AUDIO_12-10-15.mp3" or "AUDIO_121015.mp3" are automatically converted into the time "12:10:15". If no such format is found in the file name, the app will display the file’s creation time instead. Important notice: Once you import audio files into the app, they are stored internally and cannot be retrieved, copied, or shared. The app securely hides them and makes them accessible only for playback within the app. You can import audio files into the app in three ways: - Via in-app button: Tap the button in the top left corner to select a file directly from your device. The app will automatically copy the selected file. - Directly on your phone: Use the Files app to navigate to the app’s folder (under On My iPhone / iPad) and simply drag or copy your audio files there. - Via computer (Mac / PC): Connect your device and use Finder (on Mac) or iTunes (on Windows) to access File Sharing. From there, you can add audio files directly into the app’s folder. Supported audio formats: mp3, m4a, wav, aac, flac
