A field guide to small, sharp tools.
Notes on NoisyNo and DashLog — how to actually use them, and the honest edges: what runs offline, what needs no account, and where your data ends up. Not marketing copy. The how, and its limits.
Starting with the most recent guide.
How to automatically log every drive on your phone
Set it up once and DashLog records every drive on its own with CarPlay or your car's Bluetooth — route, distance, and speed. A four-step walkthrough, why automatic on-device logging matters, replay and GPX/CSV export. Available in English, 日本語, and Deutsch.
How to remove vocals from a song on your phone
Turn any song you already have into a clean instrumental backing track — on your phone, with no upload and no account. A four-step walkthrough, why on-device processing matters, and what a clean instrumental is good for. Available in English, 日本語, and Deutsch.
How to remove background noise from a voice memo (iPhone & Android)
Voice memos get recorded in cafes, cars, and lecture halls — the worst rooms you own. How to strip the steady noise out of an M4A or WAV memo on the phone itself, why memos come out noisier than you expect, and what a cleaner memo buys you at transcription time.
How to remove background noise from a meeting recording
Clean up a Zoom, Teams, or in-person meeting on your phone instead of uploading confidential audio to a website — a five-step walkthrough, the noise it can and can't remove, and how cleaner audio makes for better transcripts.
How to remove noise from a recording without uploading it
Clean up meeting, lecture, interview, and video audio inside your phone instead of a cloud editor — a five-step walkthrough with real screens, plus exactly where NoisyNo's processing and privacy begin and end.
