Ratings & Reviews
Slackwater now runs on iPad — the same live tides, weather, and solunar data, on a bigger screen built for it.
Also new in 1.2:
• Tide, solunar, and morning-brief notifications you can set per station
• Adjustable radar & wind playback speed
• Save any map view as your default, so the app opens right where you fish
Thanks for fishing with Slackwater. Tight lines!
