What is Slackwater?

Slackwater is a tide and solunar app for anglers, surfers and boaters. Pick the spots you actually use and it shows the tide curve, the high and low times, slack water, and the solunar windows when fish are most likely to move.

Predictions are computed on the device from NOAA harmonic data, so the app keeps working at the ramp, out on the water, and anywhere else the signal drops.

Best-day rankings, alerts before a window opens, a nearby-stations map and home screen widgets round it out, with an Apple Watch app for a glance at the tide.

Three spots are free. Premium lifts the limit and adds every feature at $24.99 a year, about $2.08 a month, with a 7-day trial, or $39.99 once for lifetime access.
