Honest answers.

Android 9 and above. We update regularly as new OS versions ship.

Android only for now. There is no scheduled iOS release at this time.

Recording metadata is managed in the app's internal database, and the actual files are saved under the device's Music folder in the app's subdirectory. You can find them in the Listen tab, and the exact path is shown under Settings > Recording path.

Microphone access is required. Pause-on-call needs the phone state permission; importing files from existing folders needs storage/media permissions. Scheduled and background behavior can be affected by your device's notification and battery-optimization settings.

Adding tags when you save a recording lets you filter the Listen tab by tag. Setting frequently-used tags as defaults applies them automatically to new recordings.

Deleted files go to the Trash and can be restored within the retention window. The default window is 60 days and is configurable in Settings.

Tap the center button on the Recording tab to start. While recording, you can pause, resume, or cancel. Tapping save opens a confirmation dialog for the name and tags before adding it to the Listen tab.

Five formats — MP3, WAV, M4A, AAC, AMR. Markers are stored in MP3, WAV, and M4A files; AAC and AMR have limited marker support.

Pick from the Hi-Fi, High, Medium, and Low presets, or set sample rate (8 kHz–96 kHz), bitrate (32–320 kbps), and mono/stereo manually. Some options are limited depending on the format.

There is no app-side limit by default — your storage is the practical ceiling. You can set a maximum length in Settings; once reached, the recording auto-saves.

Set start/end time, repeat days, and format on the Schedule screen. Scheduled recordings run on their own duration, separate from the general maximum-length setting.

It auto-starts when sound exceeds your dB threshold. Tunable parameters include silence duration, a pre-roll buffer (keeps a few seconds before the trigger), and auto-restart — useful for intermittent sources like neighbor noise or snoring.

If pause-on-call is enabled in Settings, recording pauses automatically and (optionally) resumes after the call. This works only when the phone state permission is granted.

Tap to drop a marker at key moments while recording or playing. You can jump to that point later from the playback screen. Markers are saved in MP3, WAV, and M4A; AAC and AMR have limited support.

Both are available when recording in MP3 or WAV. Mic boost helps soft voices, but pushing it too high may cause clipping or distortion.

Use trim on the playback screen to extract a segment or remove a section. The result is saved as a new file; the original stays untouched. Supported formats: WAV, M4A, MP3, AAC, AMR.

Yes — apply post-processing noise reduction to a saved file and store the result as a new version. WAV, MP3, M4A, and AAC are supported; AMR is not currently supported.

Open the Cloud Backup screen, sign in with your Google account, then run backup or sync. You choose the sync direction and scope on that screen.

Wi-Fi-only is the default — backup pauses on mobile data while the toggle is on. Turn it off to allow backup over mobile data as well.

Sign in with the same Google account on the new device, connect Cloud Backup, and run download or sync to bring your Drive-backed recordings over.

The selective-upload screen lets you pick exactly which files to back up — useful when you want to push specific recordings without uploading everything.

Mismatched files are flagged as conflicts. You decide which side to keep when resolving each conflict on the backup screen.

Yes — set up a PIN, password, or biometric authentication to lock individual recordings. You can also auto-lock new recordings or lock the entire Listen tab.

Listen-tab lock asks for authentication whenever you enter the tab. Turning on "authenticate every time" requires re-authentication even on quick re-entries, for stronger protection.

PINs and passwords cannot be recovered for security reasons. You'll need to follow the in-app reset flow to set up a new one.

Recordings are not sent off-device unless you explicitly run Google Drive backup, share, or attach them to a support inquiry. For details on data handling and analytics, please refer to the privacy policy.
