Skippers Log vs Percival

Skippers Log is your digital logbook for your yacht. Everything you can do in a good old fashioned paper logbook you can do here: - Create multiple trips for multiple ships - Record daily navigational data and weather observations - Include navigational live data from a wireless NMEA server - Automatic log entries based on the specifications you make (course change, wind change, ...) - Plot your trip on Apple map or Navionics map (active Navionics subscription required) - Print your trip with maps as a PDF - Create crew lists and print them - AIS targets shown on map (data from AIS receiver required) - Synchronize between you devices through iCloud - Display various data fields from NMEA data as overlay on your map - Fuel, water, cooking gas and outboard fuel consumption can be recorded - Take and add pictures to any day in the logbook (Premium version only) - Automatic geotag your position like e.g. "1.6 nm NW of Cape Finisterre" - Automatic download GMDSS and DWD weather forecasts (Euriope only, premium only) - Handling daily checklist (premium only) The free version of this app is limited to 1 ship, 1 trip and 40 manual log entries. Enough for a one or two week charter trip. No NMEA data are processed in the free app. In app purchase for the premium version and a 14-day free trial of the premium version. Please note, that the app will principally run on WiFi only iPads, but it is quite limited on these devices. Even if you use NMEA as your location source, automatic logging and track recording will likely reliably only happen while the app is in the foreground. You can still do manual entries, of course. To unleash the full potential you need a device with a gps receiver. Icons by Icons8

Marine Logbook - Voyage & Fix Logging: Records position fixes, averaged speed, course, and timestamps over the course of a passage. - Observations & Voice Notes: Allows sailors to record voice memos and text notes tied to specific GPS fixes. - Noon-to-Noon Calculations: Calculates traditional passage-making metrics, such as 24-hour day runs (noon-to-noon) and daily distance made good. Live Navigation Instruments - Displays passage data including averaged Speed Over Ground (SOG), Course Over Ground (COG), Velocity Made Good / Velocity Made on Course (VMG/VMC), and range/bearing to destination. - AIS & NMEA Integration: Ingests marine NMEA 0183 data streams and AIS vessel feeds (both local NMEA feeds and internet AIS) to monitor surrounding vessel traffic. ETA windows - Computes ETA estimates based on three velocity calculations. Mapping - Map Views & Waypoints: Plots the voyage track, note markers, and live positions over map layers (including NOAA charts and satellite tiles). Sharing & Passage Data - Standard & Native Exports: Exports trips in standard formats (.gpx, .csv) as well as native Percival voyage backup files (preserving tracks, notes, and voice clips) to share with other crew and sailors.
