One glance. Rising or falling, and when it turns. Tidal Arc puts a flowing tide curve on your home screen and lock screen — for any coast on Earth, fully offline.
The tide doesn't wait. Now you don't have to guess.
Tidal Arc turns tide predictions into one flowing curve — on your home screen, your lock screen, and in the app. See where the water is right now, whether it's rising or falling, and exactly when the next high and low arrive.
WIDGETS FIRST
• Medium widget: today's full curve with a live "now" marker
• Small widget: live countdown to the next high or low
• Lock screen: next tide at a glance, plus a tide-level gauge
ANY COAST ON EARTH
• 3,400+ official NOAA tide stations across the US
• Everywhere else: search any beach or harbor worldwide — tides are computed on your phone from a global satellite tide model
• Works offline at the beach — worldwide locations are computed entirely on your phone, and US stations keep a 7-day forecast cached
• Feet or meters
• No account, no subscription, no ads. Pay once.
TIDE ALERTS
• Optional notifications before the next high or low, so the turn never sneaks up on you
For surfers, beach walkers, clammers, kayakers, and anyone whose day bends around the tide.
US predictions are provided by NOAA CO-OPS. Worldwide locations are modeled estimates (EOT20 global tide model) — clearly labeled in the app, and not a substitute for official navigation products.
