This app allows you to use SailTimer products in other partner apps. First, if you have the wireless SailTimer Wind Instrument (www.SailTimerWind.com), this app can receive the transmissions and deliver them to other apps for viewing. Use this app with the the SailTimer™ chartplotter app, or with lots of other navigation, wind gauge or performance apps (https://wi-rb.com/apps/). But what if you want to see what the wind is doing up ahead, or around the next point? Then you need our crowdsourced wind maps and marine weather animations. You can get the low-cost subscription here, to view our marine weather animations in partner apps. We'll add a growing list of partner apps at https://SailTimer.boats App web page: https://wi-rb.com/api. If you have a question or feedback please email info@SailTimer.co - we’re here to help. If you are getting the app and like this wireless technology, please help out other sailors by letting them know with a quick rating on this version while you’re here.

Read full descriptionHide full description
GPX M Viewer and Route Editor processes data from single or multiple input files and filters the content based on GPX types: waypoints, tracks, and/or routes, or by an individual route or track. The application presents route and track summaries, including distances, start times, durations, and average speeds. Filtered data is displayed on Apple Maps. The selected or newly created route can be edited either on Apple Maps or OpenStreetMap, optionally with OpenSeaMap overlay. As a multi-platform application, it operates on iPhones, iPads, and Macs.
