Lay your route on the chart with a few taps and ICW Planner hands back the whole day as a timeline: when each bridge opens, how fast to run each leg, and what the tide and current are doing when you get there — from Norfolk (MM 0) to Miami and the upper Keys gateway.

Built on official data — NOAA charts, tides and currents, U.S. Coast Guard Notices to Mariners, and the bridge opening schedules published in 33 CFR 117 — and designed to keep working when the signal doesn't.
NOAA's electronic navigational charts, with all 168 ICW bridges and 231 mile markers drawn on them. Search the chart, drop marks, and keep them.
Tap points down the waterway and the whole run comes back timed, bridge by bridge. No account, no sign-up, nothing to configure first.
An arrival time at every bridge, matched against that bridge's real opening schedule — 76 opening bridges, seasonal and rush-hour restrictions included.
Sunrise, sunset and nautical twilight worked out on the phone, with an honest warning when you will not reach your stop before dark.
Your next bridge and its opening time on the lock screen and in the Dynamic Island while you are underway.
Bridges, schedules, tide stations and the sun all live on the phone, so the plan still comes out with no signal. When a clearance or a schedule changes, the correction reaches you without an App Store update.
The speed for each leg that puts you at the opening just in time instead of idling in front of it — plus a speed-against-wait comparison, so you can see what another knot actually buys you.
What a fixed bridge really gives you at your arrival time, rather than the number printed on the chart — and when the tide will let your mast through if it will not now.
NOAA current predictions folded into every leg, so arrival times account for fair and foul water instead of pretending it is slack.
Live Coast Guard bridge alerts and shoaling reports for the miles you are running that day, dropped in at the mile they apply to.
74 speed, no-wake and manatee zones with your speed through each one; 84 overhead cables and pipelines checked against your air draft at your arrival time; your beam against the lock chambers. Spoken heads-up as you enter a zone.
The history of the places you pass, read aloud as you come level with them, plus the full history of every bridge instead of the short version.
The chart, your route and the bridge timing are free and stay free. Pro adds the tide, the current, the notices and the rest of the navigator's toolkit.
