302 Waterways is the community-powered navigation app built for Delaware & Maryland coastal waters — the Indian River, Rehoboth and Assawoman bays, the Delaware Bay, the coastal inlets, and the connected tidal rivers. See what local boaters know, in real time: shifting sandbars, shoaling, hazards, no-wake areas, and the routes people actually run — all on a live chart with NOAA nautical charts and high-resolution satellite imagery. WHAT YOU GET • Live map — NOAA charts + satellite, channel markers, depth, marinas, fuel docks, and public boat ramps • Community reports — sandbars, shoaling, debris, hazards, no-wake areas, and wildlife sightings, confirmed by other boaters • Cruise mode — a heading-up, follow-along navigation view with your speed and course, that auto-zooms with your speed and calls out hazards and no-wake zones ahead • Routes — record your track by GPS and share the line so others can follow it • Conditions — tides, wind, and weather at a glance • Friends — connect with other boaters and see the routes they share with you • Mark an area — draw a caution area to warn the community Built by boaters, for our waters. Free to use. IMPORTANT: 302 Waterways is community intelligence — not a certified nautical chart and not a replacement for official charts, a dedicated GPS chartplotter, or safe seamanship. Conditions change; always navigate responsibly and carry required safety equipment.

Verdict

The call

KnowWake's advantage is ratings volume (250 vs 3) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
