No. You can start logging straight away and your catches stay on your phone. You’ll need an account to follow people, send messages, join challenges, use the Shop or buy Pro.

Yes. In You, then Settings, turn off Public tank and only your followers see your catches. You can also share your public tank with a link. If you’re under 18 your tank is always private.

In the app, go to You, then Settings, then Delete account, and confirm. It permanently removes your profile, catches, photos, comments, messages and follows from our servers. If you subscribe to Pro, cancel that first: deleting the account doesn’t cancel an Apple subscription. More help on the support page.

The community catch heatmap, advanced stats, tide times, the AI daily briefing, offline map areas and other Pro features. The Pro screen in the app always lists exactly what you get. See Features.

Apple takes the payment. To cancel, open Settings on your iPhone, tap your name, then Subscriptions. Billing questions are on the support page.

It’s free. We’re looking for a handful of pilot venues this winter and we check every venue page with you first. See how to join as a venue.

Yes. Anyone can start a private league and share a join code, and we’ll help a few pilot clubs set theirs up. See Leagues.
