Tidewell
Can I get alerts before high and low tide?
Quick answer
Yes. Tidewell can send you a gentle alarm ahead of every high and low tide at your favourite stations — pick how much advance notice you want, and it works even offline since the prediction is already on your device.
Set it once, get reminded automatically
Choose a favourite station and set an alarm to fire a set amount of time before each high or low tide. Tidewell schedules these locally, so they still go off even if you’re offline when the tide turns.
Useful for more than the beach
Tide alarms help with far more than a swim — timing a low-tide rock-pool walk, launching or beaching a boat, digging for bait, or checking a harbour before it dries out. Set separate alarms for each station you care about.
