User Reviews

Mariner Sailing GPS & Logbook app is praised for its useful maritime navigation features, user interface, and developer responsiveness. However, multiple users report high battery usage, privacy concerns due to excessive permissions, unstable performance, and issues with subscription purchasing. The free version is limited, pushing users toward paid plans. While some users endorse it for sailing trips, others experience failures in GPS accuracy and app stability, impacting overall usability.

Pros

Useful app for maritime navigation and logging, with functionalities like route overview, distance, speed, note-taking and saving logs.
Reasonable pricing for day passes and subscriptions, making it accessible to users.
Nice user interface with a good layout, easy to read and responsive location finding.
Responsive developers who take user feedback and update the app with new features like export as plain text.
Ability to amend settings to boater's preferences including logging period and data types.

Cons

App demands excessive permissions and tracks users, raising privacy concerns.
High battery consumption even when journey tracking is disabled.
Difficulties with subscription process: users report inability to subscribe or subscribe button not functioning.
Unstable performance, with app closing unexpectedly and slow updates on some devices like Galaxy 4 watch.
Limited free functionality: only 10 minutes of tracking without subscription, making the free version nearly unusable.
