SailorsLog is a logbook app for iOS to store passages with photos, GPX track overlays on maps, passage events, weather, crew, and more. The base of its function is invisible but important: CoreData syncs bidirectionally to CloudKit, giving SailorsLog offline-capability.

One of the upcoming features described at sailorslog.io is direct webpublishing from iPad/iOS. This will come up in version 2 which is currently undergoing intense internal testing – and doing very well.

SailorsLog v1.3.3 (not yet including webpublishing) is live on the App Store.
