The app lives in two editions:
The Sailor Logbook App can be identified by this icon:
It's a paid upfront app, i.e. it's bought at the App Store. Full functionality is at hand, without subsequent expense.
This edition will not be developed further.
The Sailor Logbook App S is identified by this icon:
S stands for Subscription. The S edition is free to download and install, but has limited functionality until an auto-renewable subscription is purchased.
This edition will be developed further.
Version 1.0 of the S edition had functionality equal to Version 2.5 of the paid upfront edition.
For details, consult the Sailor Logbook S App manual, Subscribe.
The same data model applies to the two editions. It's a subset of the data model at the Website. This means that uploads to the Website from one edition is downloadable to the other edition.
Should you want to change to the S edition and keep all your data, follow these steps:
