ANDROID · CLOSED TEST

Your waters. Your feedback.

Help us improve Kurshalter on real Android phones. Try the charts, offline use and controls – and tell us what needs work.

You will test the free version with one region of your choice. No purchase required. Kurshalter is a planning and information tool, not a substitute for current official nautical charts.
