Ringtone Maker is a free Android app that lets you create custom ringtones from your own audio files. Trim, cut, and edit any audio track directly on your device and set it as your ringtone, alarm, or notification sound.
The app works entirely with audio files you already have on your device. No content is downloaded or distributed by the app itself, and no audio file ever leaves your device.
Features: trim and cut audio tracks with a simple waveform editor, set ringtones, alarms, and notifications directly from the app, support for common audio formats (MP3, WAV, M4A, OGG), fade in/out effects, and save your custom ringtones to your device.
