What makes it different

A sailing app that actually works at sea.

Works fully offline

Voice transcription runs on your phone — no signal, no problem. Cloud sync is opportunistic, never required. Cross the Atlantic without the app degrading.

Hands-free logbook

Hold the button, speak naturally, release. Wind, position, course, sails — extracted automatically into structured data. Audio kept for verification. Searchable forever.

Your data is yours

End-to-end encrypted sync (we can't read it). One-tap export to a documented open format. Optional self-managed backups. Account-less mode supported.

No ads. No tracking.

One-time purchase plus optional cheap sync subscription. No third-party trackers. We don't analyse your boat data for any purpose other than making this app work for you.

A Tuesday at 03:42

"Wind's shifted. I should log this before I forget."

You're on watch alone in the cockpit. It's raining lightly. The wind has just clocked from NW to N — you can feel it in the sail. You want to log it before it slips your mind, but it's dark, your hands are wet, and you're holding on with one of them.

You pull out your phone. Hold the voice button. "Wind shift north fifteen knots." Release. The entry is logged with timestamp, GPS position, and structured wind data — extracted from what you said, on your phone, no signal needed.

— Six seconds. Two taps. Done.

Built for sailors who don't trust easily.

Most sailing apps treat your data as theirs. We don't. The principles page is in the app itself, viewable offline, written plainly. Here's the short version:

  • Your data is yours.End-to-end encrypted. Exportable anytime.
  • No ads. No data sales.No third-party trackers. Ever.
  • The app works without us.Offline-first. 12 months notice if we ever shut down.
  • You decide.Account-less mode. Self-managed backups. One-tap cancel.
  • Built because we sail.And we wanted what we needed.

Sail with us during the beta.

We're looking for cruising sailors to use Helm in real conditions before public launch. If you sail more than a week a year and you're on Android, we'd love your feedback.

We'll only email you about Helm. No newsletter, no marketing, no list-sharing.

Thanks — we'll be in touch when the beta opens.
