1. Can download but don't pay for it.A good app, let down only by the clunkiness of the controls for moving viewing location when trying to view leading lights.Clear and provides information during day and night.
2. Great app to help with learning marine navigation aids by night, courtesy of the light renderer that lets you visualise it in 3D space.
3. Answers to some of the test questions are incorrect and some tests on light characteristics dont show a light at all!! In my view I wasted my money in buying the this app.
4. Similarly, the port navigation simulation is also excellent for the same reason, effectively letting you visualise harbour entries and exits.Could be a useful app unfortunately the software regularly locks up.
5. I would not recommend this appI paid for the lights and shapes app only to find plenty of errors.
6. Anyway, I am not the only one who spotted the errors.
7. excellentsimple and very usefulThe app is not opening.
8. Though I did not pay for this app, I doubt it will be any better.
