Tidey shows which way the tide is flowing, how fast anywhere around the UK coast, for any date and time. THE WHOLE UK, FREE Tidal-stream arrows for all UK and Irish coastal waters, every 2 hours. The whole country downloads once, so it works offline at sea. HIGH-RESOLUTION LOCAL AREAS Where a detailed local model exists, Tidey draws it instead of the national one. PLANS • Free: national tidal streams every 2 hours. • Tidey Cruise: national tidal streams every 15 minutes. • Tidey Race: everything in Cruise, plus every high-resolution local area, including new ones as they're added. FOR RACING Course builder, wind and true wind angle, and racing marks, free for everyone. TIDE TIMES High and low water times at standard ports, marked on the map. Tap a port, or the tide button for the one nearest where you're looking. Tidey is a planning aid, not a navigation instrument. Always check official sources and conditions before going afloat. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
