What's new in Tideline 1.1 • Scrub the tide chart with your finger to read the exact height and time at any point in the day with subtle haptic feedback as you pass each hour, high, and low. • Choose which tide station each widget shows. Long-press any widget, tap Edit, and pick from stations across the US coast. Plus reliability improvements under the hood.
