Tacktiq turns every sail into data you can actually use. Record your session, see exactly where you gained and lost speed, and come back faster next time — whether you're club racing, training, or chasing a personal best. Built for keelboats and dinghies, Tacktiq reads your GPS track and boat motion to show the numbers that win races: boat speed, VMG, percentage of polar, tack and gybe quality, heel and trim, and how the wind and current moved you around the course. • RECORD EVERY SAIL Unlimited session recording on every tier — free, forever. Start from your phone or Apple Watch and Tacktiq logs your full track, speed, heading and heel, even with the screen locked. • SPEED AND VMG See your boat speed and VMG against your polar targets, broken down by leg and point of sail. Instantly spot the angles where there's more speed to find. • POLARS FOR YOUR BOAT Build a polar for each boat, import one, or let Tacktiq learn your real numbers from the sessions you sail — so every comparison is tuned to your boat, not a generic curve. • TACK AND GYBE ANALYSIS Automatic maneuver detection grades every tack and gybe on how much speed you kept through the turn — the thing that actually costs you places — plus recovery time, so you know exactly which maneuvers to drill. • START LINE TIMER A proper racing countdown (5-4-1-0, 3-2-1-0, 2-1-0 or custom) with spoken and horn callouts at every signal. Tap once to sync to the committee's gun. Pro adds a Smart Start Line: ping each end to get the favored end and line bias, your distance to the line, and time-to-burn so you hit the line at full speed right on the gun. • APPLE WATCH Start and control sessions from your wrist, watch live speed, VMG and timing, and feel the whole start sequence through haptics — with the countdown and metrics mirrored live between phone and watch. • WIND, CURRENT AND TIDE Enter the wind yourself or let Tacktiq pull it automatically. Pro layers in marine data — waves and modeled ocean current — and draws a drift diagram showing how the tide set you off your ground track. • RACE ANALYSIS A wind-shift timeline with your tacks marked, so you can see whether you tacked on the headers or gave away the lift — plus laylines, start-line bias, and upwind/downwind point-of-sail breakdowns. • AI SAILING COACH (PRO) Ask the Session Analyst about any sail and get specific, on-the-water advice built from your own data and conditions — like a coach who reviewed every second of your track and told you exactly what to work on. • TRACK YOUR PROGRESS (PRO) Cloud sync and backup across devices, session compare, full-track replay, venue heatmaps, and progression-by-condition — so you can watch yourself get faster in each wind band across a whole season. • FREE VS PRO Recording is always unlimited and free — capture as many sessions as you like and review your speed, VMG, tacks and gybes on every one. Tacktiq Pro unlocks cloud sync and backup, the AI coach, marine wind/wave/current data, the Smart Start Line, and the full analytics suite (progression, heatmaps, session compare, best-in-condition comparison, and more). • WHO IT'S FOR Racers fighting for the podium, sailors learning to trim faster, and coaches and crews who want objective feedback instead of guesswork — on any boat, at any venue. Whether you're figuring out why you're slow upwind or shaving seconds off your starts, Tacktiq gives you the feedback loop the fast sailors have: sail, measure, adjust, repeat.
