Improve your experience at sea with OnCourse, the new boating and sailing navigation aid from MarineTraffic, the global leader in vessel tracking. OnCourse helps you stay aware of the traffic around you, plan your voyages, while sharing your position with your friends and loved ones through the MarineTraffic Live Map. Increase your awareness while sailing - Plan and monitor your voyage* - Calculate the optimal route* - Add your own customisable waypoints to the map - Collision detection & avoidance while sailing, with AIS - Additional information during sailing (time to next waypoint, next ETA, final ETA, distance & bearing to waypoint) Share your position on MarineTraffic.com and engage with the boaters’ community - Report your own position even if your boat is not equipped with an AIS transponder, so that your friends and family can follow you in near real-time - Track a particular boat in a race or keep in touch with friends’ boats whilst cruising - Identify other vessels that are sailing in the area (provided that they transmit their positions) Have fun! - Recognise vessels by using the Augmented Reality tool* - Try out the VR feature (requires a VR headset)* Very low data and battery consumption All standard units of measurement supported (*) Available only with OnCourse Plus subscriptions Note: OnCourse is not AIS, OnCourse simulates the data transmitted by AIS transponders; however, it only transmits data through the Internet and not over AIS radio-frequencies. The information transmitted by OnCourse is not visible by the AIS receivers of other vessels. It will only be displayed on the MarineTraffic website and apps. As such, OnCourse is a self-reporting tool that does not substitute AIS transmissions and it is not, by any means, related to the safety and navigation equipment of a vessel. Intended use Provided that Internet connectivity is available, the vessel's positions will start being reported once the OnCourse application is launched on your mobile device. Positions will continue being reported even if the app is running in the background! Broadcasting must be turned off whenever the device leaves the vessel. How to use OnCourse - Registration Required Registration for a MarineTraffic account is required in order to start reporting your position through the application. The details of the vessel must be also configured when using the app. Get more with OnCourse Plus - Global Nautical Charts - Augmented Reality tool & VR glasses support - Route Planner tool with optimal route calculation - Global Wind Forecasts (48h) - Detailed info for vessels around you Subscription name: OnCourse Plus (1 year) Subscription cost: $57.99 (USD) Subscription duration: 1 year Auto-renewable subscription: Your subscription will be renewed every year i.e. you will be charged annually For the above subscription: • Payment will be charged to iTunes Account at confirmation of purchase • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period • Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal • Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase • Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable Disclaimer This application is to be used for informational reasons and as navigation assistance.

This has not worked for over a month. Seems that nobody cares ### 1/5 — No longer provides tracking to MarineTraffic *2024-10-12* As very long term users of MarineTraffic (MT) we were really pleased to find the OnCourse app to show our position and track when out-of-range of AIS shore stations. However, a few weeks ago it stopped showing that. The Destination entered on OnCourse is still transferred to MT but position/course is not (even though OnCourse shows hundreds of positions have been sent with “Success”). We are going over to a rival app: noforeignland. ### 1/5 — Works for 5 seconds *2024-04-26* This app works for 5 seconds then switches off not prepared to buy until much better ### 5/5 — Great app and service *2024-03-31* As a cruising sailor with family and friends around the world, this is is a fantastic app that allows me to automatically share our location, heading and boat speed straight to MarineTraffic from my iPhone. There is a bug currently that defaults our status to “underway using engine” which no doubt is an easy fix. Thanks Kpler for providing this app! @sailing.orea ### 2/5 — No tracking *2023-12-25* No tracking unless you pay. This service is free on other apps. ### 1/5 — Doesn’t work *2023-03-10* I have tried setting up an account many times. It just won’t let me log in. I finally logged in but the app never seems to update my position for AIS. **Developer response:** We are sorry that this was your experience. This is not the kind of service that we pride ourselves on and we definitely would like to further review the issue. Please share your issue at https://bit.ly/3dzeALs along with more information. Looking forward to hearing from you. ### 1/5 — Doesn’t work *2023-01-30, version 2.2.15* I have tried setting up an account many times. It just won’t let me log in. ### 2/5 — Registration fail *2022-10-21* Unable to use app as registration just gives failed message every time, deleted app. **Developer response:** Hello! Thank you for sharing your feedback regarding our app. In order for us to assist with this issue, it would be helpful to have a little bit more information. Can you send any screenshots related to the issue along with your device details at https://bit.ly/3dzeALs?

Tried turn my phone hitting the arrow location button, nothing **Developer response:** Thank you for your honest feedback. We would like to better understand your case in order to assist you further. Please share your issue at https://bit.ly/3dzeALs along with more information about the vessel (MMSI). This will help us assist you properly. ### 1/5 — Won’t allow registration *2021-08-15, version 2.2.15* Registered old (paid) app with google New app won’t allow me access Old app fantastic MAJOR backslide with this **Developer response:** We appreciate the note. As we are always striving to improve our services and help our users get value from them, it would be very helpful to learn what has led you to have this conclusion on our App. You can share more details here: https://bit.ly/2GsHvCe and we will be glad to review them.
