Sailor's Deck stays free — every card, every feature, no ads. What's new: • A tip jar. If the app has helped your prep, you can now leave a one-time tip to support development. It's completely optional and unlocks nothing — the full deck is free and always will be. • A quicker way to reach us. If something isn't clicking, you can now tell us what's tripping you up in a couple of taps. We read every message, and it shapes what we fix next. Fair winds.
MoreThank you for your feedback! I hope you enjoying the app and good luck with your skipper's exam!
