## Version history (last 5 releases)

### 1.4 — 2026-09-04

New in version 1.4:

• Radio – device guides: For common VHF radios (Standard Horizon, Icom, Garmin, Raymarine, Simrad/B&G, Lowrance, Cobra, Uniden) there is now a quick guide to DSC operation — distress call, routine call and basic operation. You can save "my radio" and open it straight from the distress screen. Available offline.
• Landscape: Rotating to landscape now keeps the voyage you are viewing (previously the app jumped to the active voyage).
• Logbook: A position set by hand on the map is now tagged "Map".
• Further small improvements and bug fixes.

### 1.3 — 2026-09-01

New in version 1.3:

• What's new: The app now has its own section showing what changed in each version — via "More → What's new" and once after an update.
• Voyage chart: A voyage's track now loads reliably when you open it. A voyage recorded on another device shows its route right away, with a "Loading track …" hint while it downloads.
• More stable: Fixed a crash when opening very long voyages with many logbook pins, plus further small improvements.

### 1.2 — 2026-08-31

New in version 1.2:

• Anchor alarm with a free-drawn alarm zone: trace the alarm boundary to fit the bay, with an inner yellow warning contour that alerts you early. The anchor point can be placed independently.
• Expanded radio assistant: SÉCURITÉ now states your call sign and MMSI. Relay, acknowledgement and cancellation are ready to use. For distress calls (MAYDAY/PAN-PAN), the position's time is added in UTC when there is no fresh GPS fix.
• Logbook: set an entry's position from your current location or by picking it on the map.
• Charts: fit and zoom respect the visible area — controls no longer hide track points.
• Subscription purchases are linked to your account more reliably, plus further fixes and refinements.

### 1.1 — 2026-08-27

New: the CoCaptain app for Apple Watch.

• Speed, course and wind at a glance on your wrist.
• Log a tack, gybe, engine or sail change with a single tap.
• Arm the anchor watch from your wrist; “man overboard” as an emergency entry.
• Plus smaller improvements to the sail-trim and supply displays.

### 1.0.2 — 2026-08-25

In this update:

• Logbook entries are now grouped on the map instead of stacking on top of each other.
• For fuel and water you can see whether the values come from an NMEA/Signal K sensor or are estimated – including the source device when the sensor is on another device.
• Voyage and total distance are calculated correctly; no more phantom miles while lying still.
• Downloading large tracks runs reliably, without crashes and without missing or duplicate points.
• Smaller refinements in the boat detail and supply overview.
