Unlike WhatsApp or Messenger, which record voice through a chat service, SoundTree Recorder is built only for capturing and organizing audio on your own phone. It comes from developer CodeMarbles, costs nothing and shows no ads. The version covered here is 0.10.28, updated on August 11, 2026.
Long recordings are hard to search later
A recorder that dumps everything into one flat list gets unusable fast. Finding the one moment you need inside an hour of audio is the real problem, and SoundTree is designed around it.
The app was first released on June 9, 2026, so it is a young project. The developer puts the emphasis on bookmarks.
Marks, topic tree and page-like waveforms
You can drop marks during recording or playback to flag moments worth revisiting. Recordings are sorted into a hierarchical topic tree. The recorder includes page-like waveforms, and the live waveform scrolls while you record.
Audio is saved as M4A. You can pause and resume without starting a new file, and you can save from the notification while the screen is locked. Audio passthrough to earphones is also supported for monitoring inputs, and automatic backup can target an external drive or USB device.
What to check before installing
SoundTree Recorder runs on Android 9 or newer and weighs 6.9 MB. The developer says it asks for no network permission and keeps everything on the device, with no accounts or cloud. Since nothing is copied online, the automatic backup to an external drive or USB device is the way to protect your recordings.
The source is public on GitHub under GPL-3.0-only. The version number, 0.10.28, suggests the app is still young.
