Monitor — Rainbow's End Marine

Rainbow's End Marine

Monitor

Watch your boat. Find your way back.

A free companion to Anchoring. The boat shares the watch under an eight-character code — anyone who types it sees the same fence, hears the same alarm, and can find the boat from the dinghy dock with a bearing needle and distance.

Why it stands out

Different by design. Honest by doctrine.

Access by code, not by account.

The boat shares the watch under an eight-character code. Anyone who types that code into Monitor sees the same fence, the same plot, and hears the same alarm — no shared Apple ID required.

A link that goes quiet is an alarm.

If the connection to the boat drops, Monitor sounds an alarm. A link that has gone quiet must never look like a boat riding safely.

One arrow points at your boat.

Her bearing and distance beneath it, and her name, hull color, and photo so you can tell her from the boat next door. It still points when there is no signal.

Crew are observers, not operators.

No disarming, no silencing her alarm, no touching the fence. The crew never control the boat.

What it does

Built for the questions you actually ask at sea.

The watch, on the crew's phones.

The fence around her anchor, where she lies inside it, and an alarm if she breaks out — or falls silent.

Find her from the dinghy dock.

One arrow points at your boat, with bearing and distance. It still points when there is no signal.

Identify her at a glance.

Her name, hull color, and photo so you can tell her from the boat next door in a crowded anchorage.

Access by code.

The crew member types the eight-character code from Anchoring and they're in. No shared Apple ID required.

What it won't do

What the app won't do is a feature.

  • Monitor will not let crew disarm the watch, silence the alarm, or adjust the fence. It is read-only.

  • It will not work without Anchoring running on the boat's device with the watch armed.

  • It will not substitute for keeping a proper watch. It is an aid, not a replacement.

Monitor is an aid to judgment, not a substitute for keeping watch. A crew member ashore is not a watchkeeper. Use it to stay informed — not to stay ashore longer than conditions allow.

In review

Submitted to Apple and under review. No account, no tracking when it arrives.
