The sea stopped a year ago, and five islands have been living the same seven days ever since. Stevie takes on her great-aunt Morwen's croft on Corran, grows creatures from Tide Seeds and sails the Glass Sea to find out where Morwen went.
Till, plant, water, harvest and ship. Tidewater from the glowing rock pools is special: anything watered with it remembers, and keeps growing through the rewind.
Plant a Tide Seed and a creature grows from it. Well water, tidewater or rain decides its form. Sproutlings follow you, open paths with their element and fight the Grey in turn-based battles.
Every islander keeps the same schedule each week and forgets you every Monday. Your Journal never does. Say the right thing at the right time and they remember you from then on.
Sail Morwen's boat, the Seventh, to Merrow Quay on its stilts, Cinderholm's glassworks and hot springs, the drowned orchard of Lowen and Hoarfrost, where it has been night for a year.
Each bell rung brings Stevie closer to Morwen, and to finding out why the sea stopped and what it will take to let it move again.
Corran is free to play in full. The Voyage, a one-off purchase, opens Finch's ferry, Morwen's boat and the other four islands. No ads, no account, and your save stays on your phone.
Runs on: iPhone with iOS 15 or later, and Android phones with Android 7.0 or later.
Seventh Tide is made by Dusk Engineering Services Ltd. This policy covers the Seventh Tide app for iPhone and Android. Last updated 12 November 2026.
Seventh Tide does not collect, store or share any personal data. There is no account to create, and the app contains no analytics, advertising or tracking code. Seventh Tide makes no network requests of its own.
Your saved game, your settings and whether you own the Voyage are kept only on your phone. Deleting the app deletes them.
The Voyage is bought through the App Store on iPhone or Google Play on Android. Apple or Google handles the payment and tells the app only whether the Voyage is owned; we never see your payment details or your Apple or Google Account. Their own privacy policies cover that purchase.
Seventh Tide collects nothing from anyone, including children.
If this policy changes, the new version will be posted on this page with a new date. Questions: info@duskengineering.services.
Email info@duskengineering.services and we will get back to you.
Restoring the Voyage: open the Game tab and tap Restore purchase, signed in with the Apple Account or Google Account you bought it with.
Refunds for purchases are handled by Apple at reportaproblem.apple.com, or by Google Play from your order history in the Play Store.
Saving: the game saves on its own as you play and when you leave the app. Saves are kept on your phone only and are not synced between devices.
Stuck? Open the Journal. The story so far and the questions still open are at the top, and the quest line under the clock suggests what to try next.
Android: the back button closes an open panel first, then leaves the game, which saves on the way out.
Seventh Tide is up and running, with access kept private while we polish it. Leave your email and we will let you know when you can use it.
