Big Arrow vs Visa Sailing

Big Arrow is a simple navigation app designed to direct you towards your destination when you are unwilling or unable to use cellular data, when there is no road to follow, or when you simply want a big arrow to point you towards your destination. The eponymous big arrow will indicate the direction pointing towards your selected destination, depending on your current direction (for example, if you are moving directly towards your destination, the arrow will point upwards). Only on iPhone, enabling the magnetometer allows the arrow to point in the correct direction when standing still. New destinations are added on your iPhone, and you will be able to navigate back to them using your iPhone or Apple Watch GPS, using no cellular data. On Apple Watch Series 5 and above, the integrated magnetometer (compass) can also be used to improve the responsiveness of the arrow. GPS accuracy while navigating is indicated by a number of dots (top right). It is shown only when accuracy is suboptimal. • red (1 dot): low accuracy (error margin above 66 m or 72 yd). •• yellow (2 dots): medium accuracy (error margin below 66 m or 72 yd). ••• green (3 dots) / hidden: good accuracy (error margin below 16 m or 17 yd). The indicator should disappear shortly after the 3 dots are shown. On Apple Watch, it also supports a compass mode that will point you towards north.. Additional features: • Notifications to alert when you are nearby a destination, or about to reach it • Battery saving mode • Handoff from Watch to iPhone • Apple Maps extension to add destinations from Apple's Maps app

Visa Sailing helps you hold a steady course using sound, not sight. It is built to aid visually impaired sailors, turning your phone into a talking compass that keeps you on heading through every passage. Lock your target heading, then let Visa guide you. As your bow drifts, Visa speaks the deviation and plays clear audio cues so you can correct by ear and keep both hands on the helm. HEAR YOUR WAY Choose how Visa talks to you. Pick spoken announcements, simple tones, or both together. Drift to port sounds on one side and drift to starboard on the other, so the direction to correct is instantly clear. STAY ON COURSE Set a target heading with a single tap, or enter one by hand. Visa tells you when you are on course and warns you the moment you begin to wander, with faster cues as the deviation grows. BUILT FOR SCREEN READERS Every screen, button and value is designed to work with VoiceOver and TalkBack. Headings, live readings and status changes are announced clearly, with large high contrast text for visually impaired sailors. This is real accessibility, built in from the start, not added on at the end. ACCURATE HEADINGS Visa blends compass, motion and location sensors to give a stable heading even in a rolling sea. Boat calibration corrects for magnetic interference on your vessel, and your location is used to adjust for magnetic declination so your heading stays true. REVIEW YOUR JOURNEYS Visa saves a summary of each trip, including your target heading, your average deviation and how long you sailed, so you can look back on how each passage went.
