Fountain tide journal
Chart every fountain throw, tide phase, and basin on your personal atlas.
Quick tabs for tide, atlas, insights, and ledger keep logging one thumb away.
See rising spots near you, streak banners, forecast cards, and optional legend whispers that pair lore with your latest coin counts.
Browse basins on a map-style atlas, open history bars for each place, and filter the ledger by tide phase to spot weekly patterns.
Capture readings with notes and photos kept in your on-device vault, compare two basins side by side, and tune alerts from preferences.
Screens from the Tide Board, basin detail, and atlas.

Cointide is designed around journals you keep for yourself. The app stores basins, tide readings, notes, and photos you add on your device. We do not operate a Cointide account system and do not receive the content of your logs through this app.
Location features, when you enable them, are used on device to suggest nearby basins and map context. You can control location access in iOS Settings at any time.
We do not sell personal information. If you contact us by email, we use your message only to respond. Analytics or crash reporting, if present in a given build, follow Apple platform policies and are limited to improving stability.
Questions about this policy: use the Support section on this page.
