The app is now Binnacle. Same tools, same account, a name that says where they live — the binnacle is the stand the compass sits in on the bridge. NEW • Manoeuvring board — CPA and TCPA for two to five contacts, and one alteration that clears them all • Heel, trim and roll period from the phone's sensors, with GM from the roll period • Coastal warnings — what the local NAVTEX carries, for the waters you are closing • Unit converter, rebuilt: 13 quantities and every unit a bridge uses CHANGED • The home screen is a live panel now: position, weather, UTC, and how many warnings are in force near you. Pull it down to refresh. • Warnings can be counted by distance from your position, and you can choose which services to follow. • A dark instrument palette throughout, meant to be read at night without wrecking your eyes. • Every tool the app has can now be pinned during setup. Four of them could not be, which was a bug nobody could see.
