iPhone
Send a ping. Follow the clues. Recover three illustrated wrecks and discover the treasures and unusual sea life hidden beneath them.
A little discovery, every day.
Tidefind is a sonar puzzle set in a quiet ocean. Send a ping and read its distance to the nearest hidden wreck. Follow the clues, recover all three ships, and try to finish in as few pings as possible. Choose the daily puzzle or explore the long voyage whenever you like.
THE LONG VOYAGE
Chart 96 expeditions across six regions, from the Glass Harbour to the Last Observatory. Read opening clues, follow a wreck's manifest and try optional recovery-order and efficiency goals. Find 24 illustrated treasures and unusual sea creatures along the way. Your route advances at any score, with no calendar waits.
WHAT LIES BENEATH
Build a logbook of lost treasures and unusual sea life. Each discovery belongs to a wreck and a themed collection, with one rare find in every series. Watch finds emerge from their recovered ships and see the missing pieces in your collection.
PLAN YOUR NEXT DISCOVERY
Choose a missing item as your mission before you dive. Earned Tide Lenses can improve its discovery chance. Your chance is shown before the first ping. Collection rewards never change your sonar clues or score.
Voyage searches make lasting progress: common finds are guaranteed by the third targeted completion and rare finds by the sixth. A missed find adds a trace; changing targets keeps those traces. Every fourth completed expedition earns a voyage lens, with occasional surprise lenses in between. Daily and voyage lenses are separate.
LEARN AT YOUR OWN PACE
Try a short guided practice dive, inspect a clue's ring of possibilities, or replay a completed sweep step by step. Compare your score with the reference sweep's par.
KEEP YOUR VOYAGES
Track completed puzzles and personal statistics, share a result, and export or import a progress backup through Files. Your collection and progress stay on your device.
YOUR OCEAN, OFFLINE
The puzzles and illustrations are included in the iPhone app. Play without an internet connection, account, advertising or in-app purchases. Reduce motion and high-contrast options are included.
One daily puzzle opens per local calendar date. This edition includes 2,200 daily seabeds, from 10 September 2026 through 17 September 2032. The 96-site voyage can be played at your own pace at any time. Finish an unfinished daily sweep before moving to today's puzzle; you can leave either mode and resume it later. Deleting the app removes local progress; keep an exported backup if you want to preserve it.
