Current Charts

Current Charts brings the current atlas to life: NOAA's tidal-current forecast for the Pacific Northwest's Salish Sea, animated on one seamless, zoomable chart. Watch flood and ebb sweep through the San Juan Islands, the Strait of Juan de Fuca, and the Gulf Islands — and scrub up to 48 hours ahead. Coverage: San Juan Islands, Gulf Islands, Strait of Juan de Fuca — the Salish Sea waters with official NOAA/CHS current predictions. SEE THE WATER MOVE Flowing trails show speed and direction everywhere at once. Eddies, races, and back-channels read at a glance — calm water looks calm, moving water moves. TAP ANYWHERE FOR A READING Tap any spot of water for its predicted speed and direction. Tap a station pin for the full flood/ebb curve, slack markers, and the next maximum — the tide-table workflow, without the tables. ANCHORED TO OFFICIAL PREDICTIONS Model currents (NOAA's SSCOFS forecast) are blended toward official NOAA current stations, and fresh predictions download automatically about twice a day. Saved predictions keep working offline — on the water, in the islands, out of cell service. PLAN AHEAD Scrub the 48-hour timeline to time a crossing, a pass, or slack at the dock. Press play and watch the day's currents unfold. PAY FOR A WEEKEND, A SEASON, OR THE YEAR Current Charts Pro is $4.99/week, $12.99/month, or $99.99/year. New subscribers get a 7-day free trial on the yearly plan. Every plan auto-renews until cancelled in your App Store settings. Family Sharing is on. No ads, ever. No tracking — your location never leaves your device. FOR PLANNING ONLY Current Charts shows model predictions, not measurements. Wind and weather change everything — never use Current Charts as your only source for navigation decisions. Made for Salish Sea boaters, paddlers, anglers, and racers.

Verdict
The clearest difference is update cadence: Current Charts at every 4 days against C's every 6 weeks. C's advantage is chart position (#111 vs unranked) and iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
