## What is Chart?

Good charts, free. No ads, no subscription, nothing to unlock, and no account needed.

Chart is a simple chart app for the water that records every outing and never locks your data in.

GOOD CHARTS, FREE
• The whole US coast from official NOAA charts — Atlantic, Gulf and Pacific, Alaska, Hawaii, Puerto Rico and the Virgin Islands, the Great Lakes, the Intracoastal Waterway and the canals
• US inland rivers from the Army Corps of Engineers' river charts — the Mississippi, Ohio, Missouri, Tennessee, Cumberland, Illinois Waterway, Tenn-Tom, Arkansas and more
• Lake depth surveys from state agencies in Connecticut, Massachusetts, New Hampshire, Michigan, Indiana and Montana, and river outlines across the US for paddlers
• New Zealand from LINZ, with the Cook Islands, Niue and Tonga, and an ocean-floor overview offshore
• Works offline: download a region and the charts, tides and app keep working with no signal
• Tides, wind and currents for the next 24 hours, and US marine warnings from the National Weather Service
• Set your boat's draft and water too shallow for you stands out

GREAT TRACKING
• Tap Record and Chart keeps your track, even with the screen off
• Your track is coloured by speed, with your position, speed and course and a line ahead of the boat
• Voice notes while you're under way, written out as text
• Day, dusk, night (red, to keep your night vision) and e-ink display modes

YOUR LOG, YOURS TO KEEP
• Every outing is saved on your phone, and always exports as GPX — no account, no lock-in
• Sign in (optional) and your outings build a boating log you can open on any device, with photos and notes
• Share a trip in one tap, so friends can replay where you went
• Crew boarding with a QR code, and family can follow along while you're out

NOT FOR NAVIGATION. Chart is not a certified navigation system and must not be your primary means of navigation. Charted data may be incomplete or out of date, and predictions are predictions. Carry official charts and keep a proper lookout.
