Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Don't get embarrassed at the fuel dock.
Sail It is a berthing and pilotage trainer for bareboat charterers, set in the real British Virgin Islands. Every harbor is built from real, openly licensed chart data and the skipper's own charts: real shorelines, real reefs, real mooring fields. Every boat handles like the boat it is, from prop walk to windage to the pause while a diesel comes through neutral.
Sail the week before you sail the week.
REAL PLACES
Twenty-two exercises across the territory: the mooring scramble at The Bight, the reef gate into Trellis Bay, the unmarked coral at Marina Cay, Anegada's channel, the slip at the charter base, the fuel docks, White Bay, Cane Garden Bay, Jost Van Dyke, North Sound and more. Each comes with a real briefing, honest depths, and neighbours already lying to their moorings.
REAL BOATS
Eight boats with genuinely different characters: sailing catamarans from 42 to 55 feet, a big monohull, twin-screw powercats with bow thrusters, and the dinghy that takes you to the beach bar. Twin screws steer on the throttles. A single screw walks its stern. A cat crabs across a crosswind. If you can dock it here, you can dock it there.
REAL SEAMANSHIP
Anchor with real scope and drag. Pick up a pennant with the boathook. Rig springs, surge a loaded line, and learn why the after bow spring is your best friend. Sail trim with a windex that tells the truth, a no-go zone you can feel, and a reef to take when she is carrying too much. A shallow-water alarm that sounds like the real instrument. Navigation lights after dark, and a night entry where the flashing gate is all you have.
MORE THAN 400 WAYS TO GET IT WRONG
Twenty harbors, eight boats and fifty-eight berths, moorings and anchorages: over 400 different exercises before you pick the wind or pull an engine. Every one of them has been sailed end to end in testing, in every boat that fits. Nobody finishes this app in a weekend.
LEARN IT IN 2½ MINUTES
A guided controls tour walks you through throttles, wheel, thruster, sails, anchor and mooring pickup. Then the coaching steps back and lets you sail.
WATCH IT BACK
Every run records itself. Nail the docking, or don't, then watch it again from the drone, frame for frame identical.
BUILT FOR THE COCKPIT
Fully offline: everything works with no signal, because that is what a boat has. Chartplotter with route, tide, cross-track error and a satellite photo layer. Engine-out drills. A ferry that will not alter for you. Painkillers on arrival. You'll see.
Not a navigation aid. Chart data © OpenStreetMap contributors (ODbL); terrain NASA/USGS SRTM via Mapzen; imagery Copernicus Sentinel-2. Depths are training estimates. Use official charts on the water.
Practice your charter. Then go live it.
What’s new
Release notes for the latest version, as written by the developer.
Cooler on the Mac and on ProMotion iPhones and iPads: a Graphics setting on the planning chart — Full, Smooth or Cool — and sixty frames a second instead of a hundred and twenty.
Mooring balls and channel marks are solid. A hull cannot pass through one; a nudge is not a collision.
The tender goes anywhere: in a yacht slip she lies against the finger, and one line makes her fast.
The Monohull 49 fuels at Road Town. The Sail cat 55 is kept off the Nanny Cay slip she does not fit.
The tender's picture in the boat picker, without the block under her.
