What's New in Tideline

2.0.1

August 3, 2026

Your widget now follows the location you've set in the app. Change it once and your home and lock screen widgets follow. You can still pin a widget to a specific station by long-pressing it and choosing Edit Widget. Fixed tide times on widgets set to a station in another time zone. Apple Watch: fixed the tide chart holding its position while you read it, and the day's best fishing times now roll into tomorrow once the last window has passed.

Best tide app for divers

I’m a PADI OWD certified scuba diver based out of Key West. I’ve found this app incredibly useful for tracking the tide for dives and other maritime activities. It’s sleek, easy to use and provides all the information I need without being cluttered. I would recommend this app to any diver or sea lover!
