The world’s most recognized database for production sailboat specifications. This is the must-have app for those looking to purchase a sailboat as well as for DIYers, sailmakers, yacht brokers, marinas, riggers, and all other marine professionals. Unlike our website, the app allows access to our database without the need for an internet connection. After downloading, you can experience the full app functionality for the first 2 hours. After that, continue on with the free basic version or subscribe to keep full access. This costs as little as a good coffee (for a yearly subscription, our cheapest option) and supports us adding more useful features and extend the database. The current features include: • Scrollable list containing over 9,200 sailboat models. • Side-by-side sailboat model compare. • Scrollable lists with all designers, builders, and associations. • The scrollable lists have an alphabetic index for quick access. • Each list has a name search bar which updates the list as you type. • Ability to select sailboats, designers, builders, and associations as your favorite. • Toggle button to quickly switch between showing all or only your favorites. • Ability to add your personal remarks for each sailboat model. • Favorites and remarks are shared between all your devices using Apple iCloud. • Refined search by LOA, LWL, Hull type, Keel type, Displacement, Beam, Draft, Rig type, Years Built and all our Ratios. • Ability to sort the refined search results on any of the search parameters. • Settings to personalize displayed units and other features. As you scroll through the sailboat list and look at sailboat and designer details, the corresponding images are downloaded via internet. Once an image has been downloaded it is stored on your device; the maximum storage used is about 500MB.

STEADYWATCH™ is a practice panel for musicians, with a button for everything, on iPhone and Apple Watch. TRACK: Play along with your music • Import audio files from the Files app. Each is analysed on your iPhone for its key, chords, tempo and bars. • See the chord now and the next one, in time with the music. • Loop any passage from A to B, snapped to the bar, with no gap. • Slow it down without changing the pitch, or transpose it up or down. • BEAT starts the track exactly on the shared beat. REC: Record yourself • A one-bar count-in on the beat, then your take, already in step with TEMPO. • Every take becomes a track: loop it, slow it down, see its chords. NOTE: A precise tuner that shows the harmonics of every note you play. CHORDS: Practice chord pairings • Pairings drawn on the circle of fifths, each in its own colours. • Turn the pairing to see how the chords connect, and play them in time. TEMPO: A metronome on atomic time • Beats sit on the same clock as every other device, so two phones (or a phone and a watch) stay in step. • It listens to you play and tells you whether you're ahead of or behind the beat. SPECTRUM: See the sound of what you play. PLAY IN TIME TOGETHER • SYNC shows a session QR code. Scan it on another device to share the tempo, bar and chord pairing. APPLE WATCH • A tuner and a haptic metronome on your wrist, in step with your iPhone. • A remote for the iPhone on its stand: play and pause, skip, loop, change the speed or key, and record, while your hands stay on the instrument. PRIVATE BY DESIGN • No account, no ads, no analytics. What the microphone hears, your takes and your tracks stay on your device.

Verdict
SailboatData and STEADYWATCH™ HANDHELD both sit at 4.8 stars, but that hides the real split: 89% of SailboatData's written reviews are positive against 0% of STEADYWATCH™ HANDHELD's. SailboatData also leads on ratings volume (301 vs 1) and iOS requirement (15.5 vs 26.2). STEADYWATCH™ HANDHELD's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 3 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SailboatData sells 4 in-app purchases, starting at $0.99 per month and STEADYWATCH™ HANDHELD sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
STEADYWATCH™ HANDHELD holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: SailboatData has 301 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of SailboatData's written reviews are positive against 0% of STEADYWATCH™ HANDHELD's, so the app with the better star average is not the one people write more warmly about.
SailboatData ships an update every 3 weeks, STEADYWATCH™ HANDHELD every 5 days. The most recent releases landed on November 11, 2026 and October 30, 2026 respectively.
