Boat Instrument
Read full descriptionHide full description
A Boat Instrument for displaying data in fully configurable Boxes. The data is received via a subscription to a SignalK server. The SignalK server should be fed from your boat's NMEA data. The SignalK server can run on any supported platform, but this is usually a Raspberry Pi running a marine specific OS build.

The clearest difference is in-app purchases: Boat Instrument at none against Boat Data's 1. Boat Instrument also leads on iOS requirement (13.0 vs 15.6). On price, ads and device support there is nothing between them.
