Gallerease VS Slackwater.xyz

Slackwater.xyz's answer:

Slackwater combines worldwide tides with tidal currents across the US and Canada, including slack water times, speed and direction. Most predictions are calculated on your device, so they work without signal. Canadian stations require an initial download, and some Canadian passes use downloaded predictions. Every station and prediction date is free.

Slackwater.xyz's answer:

Choose Slackwater if you need tide and current predictions where mobile coverage is unreliable. Interactive charts make it easy to explore upcoming conditions, while the standalone Apple Watch app puts predictions on your wrist. The core app is free, with no account, ads or tracking. Optional Premium features add alerts, calendars and more widgets.

Slackwater.xyz's answer:

People who spend time on the water or along the coast: sailors, boaters, kayakers, anglers, swimmers, beach walkers and tide-pool explorers. Tide predictions serve users worldwide, while current predictions serve people exploring the coasts and tidal passes of the United States and Canada.

Slackwater.xyz's answer:

Slackwater grew out of the makers’ own sailing in the Pacific Northwest, where tidal currents shape the day and mobile coverage can disappear. They wanted to check when a pass would go slack and how hard the current would run, even without signal. That need became an open-source app with free tide and current predictions.

Slackwater.xyz's answer:

Slackwater is built with Swift and SwiftUI for iPhone, iPad and Apple Watch. Its Swift harmonic prediction engine calculates tides and currents on the device. MapLibre powers the maps, WidgetKit provides widgets, App Intents enables Siri shortcuts, and StoreKit handles optional Premium purchases.
