Read full descriptionHide full description
SailScan is currently in beta. SailScan turns your iPhone into a sail shape analyzer. SailScan's computer vision reads the trim stripes to measure what your eyes can't quantify. Measurements include: • CAMBER DEPTH — how much shape you're carrying, stripe by stripe • DRAFT POSITION — where the depth sits, front to back • TWIST — how the top opens relative to the boom SailScan works on mainsails and jibs, from small one-design boats to grand prix racers and superyachts. Make real-time adjustments, save your scans, build your library, and start connecting your rig settings to increase speed and progress on the water. WHY IT MATTERS Good trimmers develop an eye over decades. SailScan gives you the numbers behind that eye—so you can repeat fast settings, compare tack to tack, and debrief with data instead of memory. HOW IT WORKS 1. Photograph your sail (main or jib) from below 2. SailScan detects the stripes and calculates shape metrics 3. Review, adjust, and save your scans 4. Compare scans across the day—track every setting change BUILT BY SAILORS SailScan was built by people who race and trim for a living. Join us!

Verdict
The clearest difference is price: Sail Scan at Free against BoatNotes Pro's $4.99. Sail Scan also leads on update cadence (daily vs every 3 days) and iOS requirement (15.1 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
