Where it works
Tide predictions cover the United States (including Hawaii, Alaska, Puerto Rico and Guam), Japan and South Korea. Japanese stations show tide names (潮名), moon age and the lunar calendar; Korean stations show 물때 (7물때식 and 8물때식), 음력, tidal range and current strength.

TideCatch Pro is a one-time purchase: unlimited catches, up to 6 photos per catch, stats, CSV and GPX export, iCloud sync and unlimited alerts. No subscription, no trial that turns into a charge. Family Sharing supported.
