Recorder

On-device audio recorder using your phone microphone. Record locally, mark timestamps, and export session data.

Local-first: Microphone is used only after you press Enable Mic. Audio stays on-device, and recordings remain local until you download them. Nothing uploads automatically.
Status: idle Timer: 00:00
Level: 0.000
Notes: Most browsers require HTTPS and a user gesture for microphone access. If you hit an error, check site permissions.
