Photograph the whole fish side-on, then answer a short set of observable field-mark questions about its shape, pattern, fins and size. FishKey narrows the bundled species catalogue privately on your device, with no photo upload, model download or paid scan.

Set a home spot (Spots → choose a mark → set as home). Conditions, tides and bite windows are fetched for your active spot's coordinates.

On iPhone, open Profile → CAST Pro → Manage App Store subscription. For a subscription bought on castfishingapp.com, sign in on the website and use Profile → Manage subscription. Cancelling stops renewal at the end of the current period.

In the app: Settings → Delete account. This permanently removes your profile, catches, photos and posts.

Email us with your device model and what you were doing — screenshots help enormously.
