Speed Speak vs Hull Speed

Want to know how fast you're going, without having to look at your iPhone screen? Speed Speak is a talking speedometer, which announces your speed aloud using text-to-speech technology! Use it while skateboarding, cycling, sailing, kayaking, gokarting, blokarting, skiing, snowboarding... or anywhere where you don't (or perhaps do) have a dashboard! Options screen allows you to choose between: * miles per hour * kilometers per hour * knots * US, UK and AU voices Configure how often, or at what speed intervals, you'd like your speed announced. ---- Note: SpeedSpeak isn't a substitute for your vehicle's speedometer. It is dangerous (and might be illegal) to use your iPhone while driving. Always drive below the speed limit and pay attention to the road.

Hull Speed is a simple speedometer for sailors. It shows your speed over the water in knots — big, clear, and accurate — on your iPhone and Apple Watch, with nothing else to clutter the display. Built for trimming sails: make a small adjustment, then watch the live trend graph to see if the speed changed. FEATURES • Accurate GPS speed in knots, updated every second, using the same Doppler method as dedicated marine instruments — no paddlewheel to foul or calibrate. • A live speed graph on a steady, fixed scale, so a small gain from a trim change is easy to spot. • Enter your boat's waterline length and Hull Speed draws your theoretical hull speed right on the graph — see at a glance how close you are to it. • Apple Watch app with a Keep Awake mode that holds the screen on while you sail. • Completely private — your location is used only to compute speed on your device, and is never stored, sent, or shared. No accounts, no ads, no tracking.
