BoltRecorder

Why it exists

Most recorder apps hold your entire recording in memory and only commit it when you press stop. That works right up until it doesn't — the app gets killed in the background, the battery dies, the phone reboots — and a two-hour lecture becomes a zero-byte file.

BoltRecorder writes continuously. At any moment, the audio already captured is on disk. If something goes wrong at minute 94, you keep the first 94 minutes.

What it does

• Writes to disk every three seconds The recording is flushed continuously rather than held until you stop, so an interruption costs you seconds instead of the whole session.
• Keeps recording in the background A foreground service and wake lock keep capture running with the screen off or another app in front, with a persistent notification showing status so it is never recording without you knowing.
• WAV, OGG and AAC Uncompressed WAV when you need the fidelity for editing or transcription, OGG or AAC when you need the file to stay small.
• Straightforward playback Play, pause and seek within a recording from the app. No editor, no timeline, no effects rack — just the controls you need to check what you captured.
• A recording list you can manage Every recording shows its name, duration, file size and date. Rename the ones worth keeping, delete the ones that aren't.
• Files you can get at Recordings land in the shared Recordings/BoltRecorder folder through Android's MediaStore, so any file manager, media player or USB transfer can reach them. Nothing is locked inside the app.

What it doesn't do

BoltRecorder does not request Android's internet permission at all. It cannot upload a recording, phone home, or load an ad even if it wanted to — the capability simply isn't in the app. There is no account, no cloud sync, and no analytics.
