Watercraft™
Read full descriptionHide full description
A precision instrument for carp anglers. watercraft holds what you work out for yourself: sessions, catch reports, spots, and the slow-earned knowledge of your waters. It gives it back when you ask. Everything is private by default. WATERS Add the lakes and rivers you fish. Each water carries its own illustrated lake map with numbered swims, drawn from watercraft's own database. SESSIONS The spine of the app. Begin a session, log conditions and notes as you go, and close with a summary worth keeping. The calendar holds every trip, with moon phase alongside. CATCH REPORTS File each capture properly: weight, water, swim, conditions, photo. A clean record of your angling, not a feed for anyone else. SPOTS Mark the spots that matter, down to the exact yard, and keep them where they belong. With you. PATTERNS Over time, watercraft reads your own records back to you: conditions, windows, what has worked and where. Not tips, not predictions. Your data, organised. WHAT IT ISN'T Not a social feed. No public swims, no grid of grinning captures, no algorithm. Not a leaderboard. Not a coach. It will not tell you where to fish or when to strike. Not a place to broadcast a spot. What you file is yours. The default is private, the only default that makes sense. MEMBERSHIP watercraft is free to download. Full access is £39 per year as an auto-renewing subscription, or by single Session Pass at £4.99, with a three-pack at £12.00. Payment is charged to your Apple ID account at confirmation of purchase.
