SKipper App
Read full descriptionHide full description
SKipper, as the name suggests, is an application for helping you operate your boat. The first two letters, "SK", are capitalized because SKipper uses the Signal K protocol, and can display any data available on a Signal K server. If your Signal K installation uses relays or any SignalK PUT-capable device, SKipper can also control them.

Verdict
The clearest difference is price: WinDat Opener at $5.99 against SKipper App's $12.99. SKipper App's advantage is update cadence (every 2 months vs every 5 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
